This application is related to the following co-pending application assigned to the Assignee of the present invention.
a. application Ser. No. ______, filed Jun. 13, 2017, entitled “Method and Apparatus for Providing Auto Space Management Using Virtuous Cycle,” invented by the same inventors with an Attorney's docket No. 1152.P0001US.
The exemplary embodiment(s) of the present invention relates to the field of communication networks. More specifically, the exemplary embodiment(s) of the present invention relates to a virtuous cycle between cloud, machine learning, and containerized sensors to perform a task.
With increasing popularity of automation and intelligent electronic devices, such as computerized machines, IoT (the Internet of Things), smart vehicles, smart phones, drones, mobile devices, airplanes, artificial intelligence (“AI”), the demand of intelligent machine and faster real-time response are increasing. For machine learning to become mainstream, a significant number of pieces, such as data management, model training, and data collection need to be improved.
A conventional type of machine learning is, in itself, an exploratory process which may involve trying different kinds of models, such as convolutional, RNN, attentional, et cetera. Machine learning or training typically concerns a wide variety of hyper-parameters that change the shape of the model and training characteristics. Model training generally requires intensive computation. As such, real-time response via machine learning model can be challenging.
One embodiment of the presently claimed invention discloses a method or system capable of detecting operator behavior (“OB”) utilizing a virtuous cycle containing sensors, machine learning center (“MLC”), and cloud based network (“CBN”). In one aspect, the process monitors operator body language captured by interior sensors and captures surrounding information observed by exterior sensors onboard a vehicle as the vehicle is in motion. For example, an interior camera is activated to capture operator facial expression and activating a motion detector to detect operator body movement. Also, the outward-looking cameras situated on the vehicle are activated to capture images as the vehicle is in motion. After selectively recording the captured data in accordance with an OB model generated by MLC, an abnormal OB (“AOB”) is detected in accordance with vehicular status signals received by the OB model. Upon rewinding recorded operator body language and the surrounding information leading up to detection of AOB, labeled data associated with AOB is generated. The labeled data is subsequently uploaded to CBN for facilitating OB model training at MLC via a virtuous cycle.
In one aspect, after separating real-time data from the labeled data, the real-time data is uploaded to the cloud based network in real-time via a wireless communication network. Similarly, upon separating batched data from the labeled data, the batched data is uploaded to the cloud based network at a later time depending on traffic condition(s). After feeding real-time labeled data from the vehicle to the cloud based network for correlating and revising labeled data, the revised labeled data is subsequently forwarded to the machine learning center for training OB model. After training, the trained OB model is pushed to the vehicle for continuing data collection.
In one example, after correlating the labeled data with location information, time stamp, and vicinity traffic condition obtained from the CBN to update correlated labeled data relating to the AOB, the labeled data is correlated with local events, additional sampling data, and weather conditions obtained from the cloud based network to update the correlated labeled data relating to the AOB. The process is capable of correlating the labeled data with historical body language samples relating to the operator body language of OB samples obtained from the CBN for update the correlated labeled data. For example, the labeled data is revised or correlated in response to one of historical samples relating to facial expression, hand movement, body temperature, and audio recording retrieved from the cloud based network.
The containerized OB model is trained in accordance with the correlated labeled data forwarded from the cloud based network to the machine learning center. Upon detecting an event of distracted driver in response to the correlated labeled data updated by the cloud based network, a warning signal is provided to the operator indicating the AOB based on the event of the distracted driver. The event of distracted driver is recorded or stored for future report. Note that the containerized OB model is pushed to an onboard digital processing unit in the vehicle via a wireless communication network.
A network configuration or OB system able to detect OB using a virtuous cycle includes a vehicle, CBN, and LMC. In one embodiment, the vehicle is operated by a driver containing a sensing device configured to collect data relating to operator body language of driver and surrounding information. The vehicle is configured to selectively record surrounding information observed by its onboard sensors in accordance with instructions from an OB model when the vehicle is in motion. The CBN which is wirelessly coupled to the sensing device correlates and generates labeled data associated with OB based on historical OB cloud data and the collected data. MLC coupled to the CBN trains and improves the OB model based on the labeled data from the cloud based network.
In one embodiment, the vehicle includes forward-looking cameras configured to collect real-time images as the vehicle moves across a geographical area. The sensing device of the vehicle includes a memory, controller, and transmitter, wherein the memory stores at least a portion of real-time images collected by the forward-looking cameras installed on the vehicle. The vehicle includes inward-looking cameras configured to collect real-time images relating to driver body language during the vehicle moves across a geographical area. The vehicle is able to detect an AOB based on vehicular status signals generated by a head unit of the vehicle.
In an alternative embodiment, a process configured to detect a sign utilizing a virtuous cycle containing sensors, MLC, and CBN is capable of storing real-time data captured by an onboard outward-looking cameras installed on the vehicle based on instructions from a sign model when the vehicle is driving. After detecting a sign image when the vehicle captures a predefined sample image, the stored real-time data is retrieved from a local memory to compare the predefined sample image against the captured sign image. Upon generating labeled data associated with the sign in response to the stored real-time data and historical cloud data, the labeled data relating to sign reading is uploaded to CBN for facilitating model training relating to the sign model at a machine learning process via a virtuous cycle.

Moreover, it will be understood that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skills in the art having the benefit of embodiment(s) of this disclosure.

In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or method. The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts.
In accordance with the embodiment(s) of present invention, the components, process steps, and/or data structures described herein may be implemented using various types of operating systems, computing platforms, computer programs, and/or general purpose machines. In addition, those of ordinary skills in the art will recognize that devices of a less general purpose nature, such as hardware devices, field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), or the like, may also be used without departing from the scope and spirit of the inventive concepts disclosed herein. Where a method comprising a series of process steps is implemented by a computer or a machine and those process steps can be stored as a series of instructions readable by the machine, they may be stored on a tangible medium such as a computer memory device (e.g., ROM (Read Only Memory), PROM (Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), FLASH Memory, Jump Drive, and the like), magnetic storage medium (e.g., tape, magnetic disk drive, and the like), optical storage medium (e.g., CD-ROM, DVD-ROM, paper card and paper tape, and the like) and other known types of program memory.
The term “system” or “device” is used generically herein to describe any number of components, elements, sub-systems, devices, packet switch elements, packet switches, access switches, routers, networks, computer and/or communication devices or mechanisms, or combinations of components thereof. The term “computer” includes a processor, memory, and buses capable of executing instruction wherein the computer refers to one or a cluster of computers, personal computers, workstations, mainframes, or combinations of computers thereof.
One embodiment of the presently claimed invention discloses an operator behavior system (“OBS”) capable of detecting OB utilizing a virtuous cycle containing sensors, machine learning center (“MLC”), and cloud based network (“CBN”). In one aspect, the process monitors operator body language captured by interior sensors and captures surrounding information observed by exterior sensors onboard a vehicle as the vehicle is in motion. After selectively recording the captured data in accordance with an OB model generated by MLC, AOB is detected in accordance with vehicular status signals received by the OB model. Upon rewinding recorded operator body language and the surrounding information leading up to detection of AOB, labeled data associated with AOB is generated. The labeled data is subsequently uploaded to CBN for facilitating OB model training at MLC via a virtuous cycle.
Vehicle 102, in one example, can be a car, automobile, bus, train, drone, airplane, truck, and the like, and is capable of moving geographically from point A to point B. To simplify forgoing discussing, the term “vehicle” or “car” is used. Vehicle 102 includes wheels with ABS (anti-lock braking system), body, steering wheel 108, exterior or forward-looking cameras 136, interior or 360° (degree) interior camera 137, antenna 134, onboard controller 132, and operator (or driver) 116. It should be noted that interior and/or exterior cameras 136-137 can be installed at front, side-facing, stereo, and inside of vehicle 102. In one example, vehicle 102 also includes various sensors which senses information related to vehicle state, vehicle status, driver actions, For example, the sensors, not shown in
Onboard controller 132 includes CPU (central processing unit), GPU (graphic processing unit), memory, and disk responsible for gathering data from exterior cameras 136, interior cameras, audio sensor, ABS, traction control, steering wheel, CAN-bus sensors, and the like. In one aspect, controller 132 executes OB model received from MLC 106, and interfaces with antenna 134 to communicate with CBN 104 via a wireless communication network 110. Note that wireless communication network includes, but not limited to, WIFI, cellular network, Bluetooth network, satellite network, or the like. A function of controller 132 is to gather or capture real-time surrounding information when the vehicle is driving.
CBN 104 includes various digital computing systems, such as, but not limited to, server farm 120, routers/switches 122, cloud administrators 124, connected computing devices 126-128, and network elements 118. A function of CBN 104 is to provide cloud computing which can be viewed as on-demand Internet based computing service with enormous computing power and resources. A function of CBN 104 is to improve or refine OB labeled data via correlating captured real-time data with relevant cloud data. The refined OB labeled data is subsequently passed to MLC 106 for model training via a connection 112.
MLC 106, in one embodiment, provides, refines, trains, distributes models 130 such as OB model based on information or data such as OB labeled data provided from CBN 104. It should be noted that the machine learning makes predictions based on models generated and maintained by various computational algorithms using historical data as well as current data. A function of MLC 106 is that it is capable of pushing information such as revised OB model to vehicle 102 via a wireless communications network 114 in real-time.
To identify or detect a districted driver or operator 116 of a vehicle, an onboard OB model which could reside inside of controller 132 receives a triggering event or events from built-in sensors such as ABS, wheel slippery, engine status, and the like. The triggering event or events may include, but not limited to, activation of ABS, rapid steering, rapid breaking, excessive wheel slip, activation of emergency stop, and on. Upon receiving triggering events via vehicular status signals, the recording or recorded images captured by inward facing camera or 360 camera are rewound from an earlier time stamp leading to the receipt of triggering event(s) for identifying OB labeled data which contains images considered to be dangerous driving. After correlation of OB labeled data with historical sampling data at CBN, the OB model is retrained and refined at MLC. The retrained OB model is subsequently pushed back onto vehicle 102.
In operation, when the triggering events indicate a dangerous driving or dangerous event, such event indicates a dangerous driver or distracted driver. Upon detecting a dangerous event, CBN 104 issues waning signal to driver or operator 116 via, for instance, a haptic signal, or shock to operator 116 notifying driver 116 to be careful. In addition, the dangerous event or events are recorded for report. It should be noted that a report describing driver's behavior as well as number occurrence relating to dangerous events can be useful. For example, such report can be obtained by insurance company for insurance auditing, by law enforcement for accident prevention, by city engineers for traffic logistics, or by medical stuff for patient safety.
An advantage of using an OB system is to reduce traffic accidents and enhance public safety.
In one embodiment, the OB system is able to detect distracted driver, texting, facial recognition, and driver restriction. It should be noted that the car may contain multiple forward facing cameras (or 360-degree camera(s)) capable of capturing a 360 view which can be used to correlate with other views to identify whether driver 148 looks back to see a car behind the driver or to look at the side when the car turns. Based on observed OB, the labeled data showing looking at the correct spots based on traveling route of car can illustrate where the danger is. Alternatively, the collected images or labeled data can be used to retrain OB model which may predict the safety rating for driver 148. It should be noted that the labeled data should include various safety parameters such as whether the driver looks left and right before crossing an intersection and/or whether the driver gazes at correct locations while driving.
It should be noted that sensor or sensors mean camera, Lidar, radar, sonar, thermometers, audio detector, pressure sensor, airflow, optical sensor, infrared reader, speed sensor, altitude sensor, and the like. OB can also change based on occupant(s) behavior in the vehicle or car. For example, if occupants are noisy, loud radio, shouting, drinking, eating, dancing, the occupants behavior can affect overall OB contributes to bad driving behavior.
Based on the facial expression with vehicular status signals indicating triggering event, the OB model can measure operator emotion and attention to conclude whether the operator is angry (i.e., road rage) or signs of incapacity.
In operation, a car having a SR model passes a location known to have a traffic sign, electrical pole, light pole, etc. by consulting the municipal database. After the camera data is captured of the car approaching the sign, the camera images and type of sign from the municipal data are used as labeled data. For electrical poles with identification codes, the camera image can be labeled with the identification code. It should be noted that the value of electrical pole identification code recognition is that the electrical poles are very precisely located and so they can be used to correct GPS readings, particularly in areas where there are multi-path problems. Note also that to provide electrical pole recognition, side-view camera(s) is required on the car.
Alternatively, the SR system can also be used to identify stationary objects such as stores, retail locations, bridges, buildings, houses, light towers, landmarks, and so on. Upon correlating maps such as Google™ maps or open street maps for tags, the captured image can be relatively easy to train. For example, the SR system can be trained to identify nearby Starbucks™ or McDonald's™ in a certain geographic area. The SR system, in on example, can also be configured to recognize construction barriers and roadblocks to enhance operation safety.
The virtuous cycle illustrated in diagram 200, in one embodiment, is configured to implement AOB system wherein containerized sensor network 206 is similar to vehicle 102 as shown in
Real-world scale data 202, such as cloud or CBN, which is wirelessly coupled to the containerized sensing device, is able to correlate with cloud data and recently obtained OB data for producing labeled data. For example, real-world scale data 202 generates OB labeled data based on historical OB cloud data and the surrounding information sent from the containerized sensing device.
Continuous machine learning 204, such as MLC or cloud, is configured to train and improve OB model based on the labeled data from real-world scale data 202. With continuous gathering data and training OB model(s), the AOB system will be able to learn, obtain, and/or collect all available OBs for the population samples.
In one embodiment, a virtuous cycle includes partition-able Machine Learning networks, training partitioned networks, partitioning a network using sub-modules, and composing partitioned networks. For example, a virtuous cycle involves data gathering from a device, creating intelligent behaviors from the data, and deploying the intelligence. In one example, partition idea includes knowing the age of a driver which could place or partition “dangerous driving” into multiple models and selectively deployed by an “age detector.” An advantage of using such partitioned models is that models should be able to perform a better job of recognition with the same resources because the domain of discourse is now smaller. Note that, even if some behaviors overlap by age, the partitioned models can have common recognition components.
It should be noted that more context information collected, a better job of recognition can be generated. For example, “dangerous driving” can be further partitioned by weather condition, time of day, traffic conditions, et cetera. In the “dangerous driving” scenario, categories of dangerous driving can be partitioned into “inattention”, “aggressive driving”, “following too closely”, “swerving”, “driving too slowly”, “frequent breaking”, deceleration, ABS event, et cetera.
For example, by resisting a steering behavior that is erratic, the car gives the driver direct feedback on their behavior—if the resistance is modest enough then if the steering behavior is intentional (such as trying to avoid running over a small animal) then the driver is still able to perform their irregular action. However, if the driver is texting or inebriated then the correction may alert them to their behavior and get their attention. Similarly, someone engaged in “road rage” who is driving too close to another car may feel resistance on the gas pedal. A benefit of using OB system is to identify consequences of a driver's “dangerous behavior” as opposed to recognizing the causes (texting, etc.). The Machine Intelligence should recognize the causes as part of the analysis for offering corrective action.
In one aspect, a model such as OB model includes some individual blocks that are trained in isolation to the larger problem (e.g. weather detection, traffic detection, road type, etc.). Combining the blocks can produce a larger model. Note that the sample data may include behaviors that are clearly bad (ABS event, rapid deceleration, midline crossing, being too close to the car in front, etc.). In one embodiment, one or more sub-modules are built. The models include weather condition detection and traffic detection for additional modules intelligence, such as “correction vectors” for “dangerous driving.”
An advantage of using a virtuous cycle is that it can learn and detect object such as OB in the real world.
In one aspect, in-cloud components and in-device components coordinate to perform desirable user specific tasks. While in-cloud component leverages massive scale to process incoming device information, cloud applications leverage crowd sourced data to produce applications. External data sources can be used to contextualize the applications to facilitate intellectual crowdsourcing. For example, in-car (or in-phone or in-device) portion of the virtuous cycle pushes intelligent data gathering to the edge application. In one example, edge applications can perform intelligent data gathering as well as intelligent in-car processing. It should be noted that the amount of data gathering may rely on sensor data as well as intelligent models which can be loaded to the edge.
Crowdsourcing is a process of using various sourcing or specific models generated or contributed from other cloud or Internet users for achieving needed services. For example, crowdsourcing relies on the availability of a large population of vehicles, phones, or other devices to source data 302. For example, a subset of available devices such as sample 304 is chosen by some criterion such as location to perform data gathering tasks. To gather data more efficiently, intelligent models are deployed to a limited number of vehicles 306 for reducing the need of large uploading and processing a great deal of data in the cloud. It should be noted that the chosen devices such as cars 306 monitor the environment with the intelligent model and create succinct data about what has been observed. The data generated by the intelligent models is uploaded to the correlated data store as indicated by numeral 308. It should be noted that the uploading can be performed in real-time for certain information or at a later time for other types of information depending on the need as well as condition of network traffic.
Correlated component 308 includes correlated data storage capable of providing a mechanism for storing and querying uploaded data. Cloud applications 312, in one embodiment, leverage the correlated data to produce new intelligent models, create crowd sourced applications, and other types of analysis.
In one embodiment, correlated data store 402 manages real-time streams of data in such a way that correlations between the data are preserved. Sensor network 406 represents the collection of vehicles, phones, stationary sensors, and other devices, and is capable of uploading real-time events into correlated data store 402 via a wireless communication network 412 in real-time or in a batched format. In one aspect, stationary sensors includes, but not limited to, municipal cameras, webcams in offices and buildings, parking lot cameras, security cameras, and traffic cams capable of collecting real-time images.
The stationary cameras such as municipal cameras and webcams in offices are usually configured to point to streets, buildings, parking lots wherein the images captured by such stationary cameras can be used for accurate labeling. To fuse between motion images captured by vehicles and still images captured by stationary cameras can track object(s) such as car(s) more accurately. Combining or fusing stationary sensors and vehicle sensors can provide both labeling data and historical stationary sampling data also known as stationary “fabric”. It should be noted that during the crowdsourcing applications, fusing stationary data (e.g. stationary cameras can collect vehicle speed and position) with real-time moving images can improve ML process.
Machine Learning (“ML”) framework 404 manages sensor network 406 and provides mechanisms for analysis and training of ML models. ML framework 404 draws data from correlated data store 402 via a communication network 410 for the purpose of training modes and/or labeled data analysis. ML framework 404 can deploy data gathering modules to gather specific data as well as deploy ML models based on the previously gathered data. The data upload, training, and model deployment cycle can be continuous to enable continuous improvement of models.
In one aspect, a correlated system includes a real-time portion and a batch/historical portion. The real-time part aims to leverage new data in near or approximately real-time. Real-time component or management 508 is configured to manage a massive amount of influx data 506 coming from cars, phones, and other devices 504. In one aspect, after ingesting data in real-time, real-time data management 508 transmits processed data in bulk to the batch/historical store 510 as well as routes the data to crowd sourced applications 512-516 in real-time.
Crowd sourced applications 512-516, in one embodiment, leverage real-time events to track, analyze, and store information that can be offered to user, clients, and/or subscribers. Batch-Historical side of correlated data store 510 maintains a historical record of potentially all events consumed by the real-time framework. In one example, historical data can be gathered from the real-time stream and it can be stored in a history store 510 that provides high performance, low cost, and durable storage. In one aspect, real-time data management 508 and history store 510 coupled by a connection 502 are configured to perform OB data correlation as indicated by dotted line.
The real-time data management, in one embodiment, is able to handle a large numbers (i.e., 10's of millions) of report events to the cloud as indicated by numeral 604. API (application program interface) gateway 606 can handle multiple functions such as client authentication and load balancing of events pushed into the cloud. The real-time data management can leverage standard HTTP protocols. The events are routed to stateless servers for performing data scrubbing and normalization as indicated by numeral 608. The events from multiple sources 602 are aggregated together into a scalable/durable/consistent queue as indicated by numeral 610. An event dispatcher 616 provides a publish/subscribe model for crowd source applications 618 which enables each application to look at a small subset of the event types. The heterogeneous event stream, for example, is captured and converted to files for long-term storage as indicated by numeral 620. Long-term storage 624 provides a scalable and durable repository for historical data.
The crowd sourced application model, in one embodiment, facilitates events to be routed to a crowd source application from a real-time data manager. In one example, the events enter gateway 702 using a simple push call. Note that multiple events are handled by one or more servers. The events, in one aspect, are converted into inserts or modifications to a common state store. State store 708 is able to hold data from multiple applications and is scalable and durable. For example, State store 708, besides historical data, is configured to store present data, information about “future data”, and/or data that can be shared across applications such as predictive AI (artificial intelligence).
State cache 706, in one example, is used to provide fast access to commonly requested data stored in state store 708. Note that application can be used by clients. API gateway 712 provides authentication and load balancing. Client request handler 710 leverages state store 708 for providing client data.
In an exemplary embodiment, an onboard OB model is able to handle real-time OB detection based on triggering events. For example, after ML models or OB models for OB detection have been deployed to all or most of the vehicles, the deployed ML models will report to collected data indicating OBs to the AOB system(s) for facilitating issuance of real-time warning for dangerous event(s). The information or data relating to the real-time dangerous event(s) or AOB is stored in state store 708. Vehicles 714 looking for OB detection can, for example, access the AOB system using gateway 712.
Geo-spatial object storage 820, in one aspect, stores or holds objects which may include time period, spatial extent, ancillary information, and optional linked file. In one embodiment, geo-spatial object storage 820 includes UUID (universally unique identifier) 822, version 824, start and end time 826, bounding 828, properties 830, data 832, and file-path 834. For example, while UUID 822 identifies an object, all objects have version(s) 824 that allow schema to change in the future. Start and end time 826 indicates an optional time period with a start time and an end time. An optional bounding geometry 828 is used to specify spatial extent of an object. An optional set of properties 830 is used to specify name-value pairs. Data 832 can be binary data. An optional file path 834 may be used to associate with the object of a file containing relevant information such as MPEG (Moving Picture Experts Group) stream.
In one embodiment, API gateway 802 is used to provide access to the service. Before an object can be added to the store, the object is assigned an UUID which is provided by the initial object call. Once UUID is established for a new object, the put call 804 stores the object state. The state is stored durably in Non-SQL store 814 along with UUID. A portion of UUID is used as hash partition for scale-out. The indexible properties includes version, time duration, bounding, and properties which are inserted in a scalable SQL store 812 for indexing. The Non-SQL store 814 is used to contain the full object state. Non-SQL store 814 is scaled-out using UUID as, for example, a partition key.
SQL store 812 is used to create index tables that can be used to perform queries. SQL store 812 may include three tables 816 containing information, bounding, and properties. For example, information holds a primary key, objects void, creation timestamp, state of object and object properties “version” and “time duration.” Bounding holds the bounding geometry from the object and the id of the associated information table entry. Properties hold property name/value pairs from the object stored as one name/value pair per row along with ID of associated info table entry.
Find call 808, in one embodiment, accepts a query and returns a result set, and issues a SQL query to SQL store 812 and returns a result set containing UUID that matches the query.
In one aspect, diagram 900 illustrates analysis engine 904 containing ML training component capable of analyzing labeled data based on real-time captured OB data and historical data. The data transformation engine, in one example, interacts with Geo-spatial object store 906 to locate relevant data and with history store to process the data. Optimally, the transformed data may be stored.
It should be noted that virtuous cycle employing ML training component to provide continuous model training using real-time data as well as historical samples, and deliver OB detection model for one or more subscribers. A feature of virtuous cycle is able to continuous training a model and able to provide a real-time or near real-time result. It should be noted that the virtuous cycle is applicable to various other fields, such as, but not limited to, business intelligence, law enforcement, medical services, military applications, and the like.

At block 1204, after selectively recording the captured data in accordance with an OB model generated by MLC, an AOB is detected at block 1206 in accordance with vehicular status signals received by the OB model. At block 1208, upon rewinding recorded operator body language and the surrounding information leading up to detection of AOB, labeled data associated with AOB is generated. At block 1210, the labeled data is subsequently uploaded to CBN for facilitating OB model training at MLC via a virtuous cycle.
In one aspect, after separating real-time data from the labeled data, the real-time data is uploaded to the cloud based network in real-time via a wireless communication network. Similarly, upon separating batched data from the labeled data, the batched data is uploaded to the cloud based network at a later time depending on traffic condition(s). After feeding real-time labeled data from the vehicle to the cloud based network for correlating and revising labeled data, the revised labeled data is subsequently forwarded to the machine learning center for training OB model. After training, the trained OB model is pushed to the vehicle for continuing data collection. In one example, after correlating the labeled data with location information, time stamp, and vicinity traffic condition obtained from the CBN to update correlated labeled data relating to the AOB, the labeled data is correlated with local events, additional sampling data, and weather conditions obtained from the cloud based network to update the correlated labeled data relating to the AOB. The process is capable of correlating the labeled data with historical body language samples relating to the operator body language of OB samples obtained from the CBN for update the correlated labeled data. For example, the labeled data is revised or correlated in response to one of historical samples relating to facial expression, hand movement, body temperature, and audio recording retrieved from the cloud based network.
The containerized OB model is trained in accordance with the correlated labeled data forwarded from the cloud based network to the machine learning center. Upon detecting an event of distracted driver in response to the correlated labeled data updated by the cloud based network, a warning signal is provided to the operator indicating the AOB based on the event of the distracted driver. The event of distracted driver is recorded or stored for future report. Note that the containerized OB model is pushed to an onboard digital processing unit in the vehicle via a wireless communication network.
