This technology generally relates to methods and systems for data analytics, and more particularly to methods and systems for providing real-time and/or near real-time analytics of time series data to identify anomalous data patterns and alert stakeholders.
Many business entities such as, for example, payment processing merchants manage large flows of time series data. The time series data may relate to important customer transaction information that impact business outcomes. Historically, implementation of conventional analytic techniques for the time series data has resulted in varying degrees of success with respect to effective and efficient identification of anomalous data patterns in the time series data.
One drawback of using the conventional analytic techniques is that in many instances, anomalous data patterns are not efficiently and effectively identified in the time series data. The anomalous data patterns may indicate malicious activities, third-party activities, and business transformations that adversely impact business outcomes. As a result, the anomalous data patterns are not mitigated in a timely manner and adversely impacts the business entity.

Also, the application(s) may be running in one or more virtual machines (VMs) executing on the TSDAA device 202. Additionally, in one or more embodiments of this technology, virtual machine(s) running on the TSDAA device 202 may be managed or supervised by a hypervisor.
In the network environment 200 of
The communication network(s) 210 may be the same or similar to the network 122 as described with respect to
By way of example only, the communication network(s) 210 may include local area network(s) (LAN(s)) or wide area network(s) (WAN(s)), and can use TCP/IP over Ethernet and industry-standard protocols, although other types and/or numbers of protocols and/or communication networks may be used. The communication network(s) 210 in this example may employ any suitable interface mechanisms and network communication technologies including, for example, teletraffic in any suitable form (e.g., voice, modem, and the like), Public Switched Telephone Network (PSTNs), Ethernet-based Packet Data Networks (PDNs), combinations thereof, and the like.
The TSDAA device 202 may be a standalone device or integrated with one or more other devices or apparatuses, such as one or more of the server devices 204(1)-204(n), for example. In one particular example, the TSDAA device 202 may include or be hosted by one of the server devices 204(1)-204(n), and other arrangements are also possible. Moreover, one or more of the devices of the TSDAA device 202 may be in a same or a different communication network including one or more public, private, or cloud networks, for example.
The plurality of server devices 204(1)-204(n) may be the same or similar to the computer system 102 or the computer device 120 as described with respect to
The server devices 204(1)-204(n) may be hardware or software or may represent a system with multiple servers in a pool, which may include internal or external networks. The server devices 204(1)-204(n) hosts the databases 206(1)-206(n) that are configured to store data that relates to sets of time series data, key metrics, machine learning models, anomalies, predetermined thresholds, transaction rates, transaction volumes, internal resources, external resources, and recommended mitigation procedures.
Although the server devices 204(1)-204(n) are illustrated as single devices, one or more actions of each of the server devices 204(1)-204(n) may be distributed across one or more distinct network computing devices that together comprise one or more of the server devices 204(1)-204(n). Moreover, the server devices 204(1)-204(n) are not limited to a particular configuration. Thus, the server devices 204(1)-204(n) may contain a plurality of network computing devices that operate using a controller/agent approach, whereby one of the network computing devices of the server devices 204(1)-204(n) operates to manage and/or otherwise coordinate operations of the other network computing devices.
The server devices 204(1)-204(n) may operate as a plurality of network computing devices within a cluster architecture, a peer-to peer architecture, virtual machines, or within a cloud architecture, for example.

Although the exemplary network environment 200 with the TSDAA device 202, the server devices 204(1)-204(n), the client devices 208(1)-208(n), and the communication network(s) 210 are described and illustrated herein, other types and/or numbers of systems, devices, components, and/or elements in other topologies may be used. It is to be understood that the systems of the examples described herein are for exemplary purposes, as many variations of the specific hardware and software used to implement the examples are possible, as will be appreciated by those skilled in the relevant art(s).
One or more of the devices depicted in the network environment 200, such as the TSDAA device 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n), for example, may be configured to operate as virtual instances on the same physical machine. In other words, one or more of the TSDAA device 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n) may operate on the same physical device rather than as separate devices communicating through communication network(s) 210. Additionally, there may be more or fewer TSDAA devices 202, server devices 204(1)-204(n), or client devices 208(1)-208(n) than illustrated in
In addition, two or more computing systems or devices may be substituted for any one of the systems or devices in any example.

Of course, these embodiments are merely exemplary and are not limiting or exhaustive.
Upon being started, the time series data analytics and alerting module 302 executes a process for providing real-time analytics of time series data to identify anomalous data patterns and alert stakeholders. An exemplary process for providing real-time analytics of time series data to identify anomalous data patterns and alert stakeholders is generally indicated at flowchart 400 in
In the process 400 of
In another exemplary embodiment, the first set of time series data may be captured in real-time from a data flow. The data flow may correspond to a stream of transaction data from the payment processing merchant. In another exemplary embodiment, the first set of time series data may be captured from the data flow based on a predetermined schedule. For example, the predetermined schedule may dictate that the first set of time series data is captured once a day.
In another exemplary embodiment, the first set of time series data may relate to historical data that is captured to establish a baseline. For example, the first set of time series data may be captured and compared to subsequently captured data to determine whether a change in the data flow has occurred. In another exemplary embodiment, the first set of time series data may be combined with other sets of time series data to determine an average set of time series data that represents a state of the data flow. The average set of time series data may relate to an arithmetic mean of a plurality of sets of time series data.
In another exemplary embodiment, the first predetermined time period may relate to a window of time. For example, the first predetermined time period may correspond to a period of one minute, one hour, one day, and/or any combination thereof. In another exemplary embodiment, the first predetermined time period may be determined based on a user preference. The user preference may be adjusted based on input received from the user via a graphical user interface. In another exemplary embodiment, the first predetermined time period may be determined automatically based on business guidelines by using automated machine learning techniques consistent with disclosures in the present application.
At step S404, the first set of time series data may be parsed to identify a first key metric. In an exemplary embodiment, the first key metric may include information that relates to a parameter of the data flow. For transactional data flows, the parameter of the data flow may correspond to at least one from among an authorization rate, a transaction rate, and a transaction volume that corresponds to attempted transactions. As will be appreciated by a person of ordinary skill in the art, parsing of the first set of time series data may require translation of the time series data as well as mapping of the time series data to convert the time series data from one data format to another data format.
In another exemplary embodiment, the first key metric may be manually determined by a user. The user may utilize a graphical user interface to indicate specific parameters that are associated with the first key metric. For example, the user may indicate that the authorization rate is associated with the first key metric. In another exemplary embodiment, the first key metric may be automatically determined based on a business guideline by using machine learning techniques consistent with disclosures in the present application. For example, based on automatically determined patterns, a parameter such as an authorization rate may be automatically identified as one of the first key metrics.
At step S406, a second set of time series data may be captured from the data flow based on a second predetermined time period. In an exemplary embodiment, the second set of time series data may relate to data that is received in a sequence at successive points in time. The data may be received at equally spaced, successive points in time as well as at successive irregular intervals. In another exemplary embodiment, the second set of time series data may include transaction information from a payment processing merchant. The transaction information may include at least one from among an authorization rate, a transaction rate, and a transaction volume that corresponds to attempted transactions.
In another exemplary embodiment, the second set of time series data may be captured in real-time from a data flow. The data flow may correspond to a stream of transaction data from the payment processing merchant. In another exemplary embodiment, the second set of time series data may be captured from the data flow based on a predetermined schedule. For example, the predetermined schedule may dictate that the second set of time series data is captured once an hour during peak transaction processing times.
In another exemplary embodiment, the second set of time series data may relate to current data that is presently captured. The second set of time series data may relate to presently captured data that represents a current state of the data flow. For example, the second set of time series data may be presently captured and compared to previously captured data to determine whether a change in the data flow has occurred.
In another exemplary embodiment, the second predetermined time period may relate to a window of time. For example, the second predetermined time period may correspond to a period of one minute, one hour, one day, and/or any combination thereof. In another exemplary embodiment, the second predetermined time period may be determined based on a user preference. The user preference may be adjusted based on input received from the user via a graphical user interface. In another exemplary embodiment, the second predetermined time period may be determined automatically based on business guidelines by using automated machine learning techniques consistent with disclosures in the present application. Consistent with disclosures in the present application, the first predetermined time period may correspond to a window of time that precedes the second predetermined time period
At step S408, the second set of time series data may be parsed to identify a second key metric. The second key metric may correspond to the first key metric. In an exemplary embodiment, the second key metric may include information that relates to a parameter of the data flow. For transactional data flows, the parameter of the data flow may correspond to at least one from among an authorization rate, a transaction rate, and a transaction volume that corresponds to attempted transactions. As will be appreciated by a person of ordinary skill in the art, parsing of the second set of time series data may require translation of the time series data as well as mapping of the time series data to convert the time series data from one data format to another data format.
In another exemplary embodiment, the second key metric may be manually determined by a user. The user may utilize a graphical user interface to indicate specific parameters that are associated with the second key metric. For example, the user may indicate that the authorization rate is associated with the second key metric. In another exemplary embodiment, the second key metric may be automatically determined based on a business guideline by using machine learning techniques consistent with disclosures in the present application. For example, based on automatically determined patterns, a parameter such as an authorization rate may be automatically identified as one of the second key metrics.
At step S410, the second key metric may be compared with the first key metric in real-time and/or near real-time. In an exemplary embodiment, the second key metric may be compared with the first key metric in actual time and/or near actual time during which the second key metric was captured from the data flow. The comparison may be processed within a substantially short amount of time such as, for example, within a millisecond, so that a result of the comparison may be available virtually immediately after the second key metric has been captured from the data flow. In another exemplary embodiment, the second key metric and the first key matric may be compared to determine a deviation between the data sets. The deviation may relate to a measured difference between the second key metric and the first key metric.
At step S412, an anomaly may be identified based on a result of the comparing and a predetermined threshold by using a model. In an exemplary embodiment, the anomaly may relate to resulting anomalous data from the comparison between the second set of time series data and the first set of time series data. The anomalous data may correspond to data that deviates from baseline behaviors of the data flow. In another exemplary embodiment, the baseline behaviors may account for seasonal deviations in the data flow. The seasonal deviations in the data flow may be used to assess whether an event, which may be unexpected in the short term, occurs on an expected periodic basis in the long term. For example, an identified anomaly may not be alerted when the anomaly is based on a known deviation in the data flow that occurs at periodic intervals such as every week, every month, etc.
In another exemplary embodiment, the anomaly may relate to at least one from among a result of malicious activity, a third-party activity, and a business transformation. The result of malicious activity may include fraudulent transaction attempts. The third-party activity may correspond to a change in issuer policy that impacts authorization rates. The business transformation may relate to a change in consumer behavior and/or a change in offered goods/services that impact the payment transactions. In another exemplary embodiment, the anomaly may have adverse impacts on a business outcome as well as adverse impacts on perceptions of the business outcome. For example, the anomaly may adversely cause a reduction in revenue and/or an increase in cost. As will be appreciated by a person of ordinary skill in the art, early detection of the anomaly may allow for appropriate responses to mitigate the adverse effects of the anomaly.
In another exemplary embodiment, the predetermined threshold may correspond to a magnitude of deviation in the time series data that indicates an anomaly. The deviation in the time series data may correspond to a measured difference between the first set of time series data and the second set of time series data. In another exemplary embodiment, the predetermined threshold may be manually defined by a user by interacting with a graphical user interface. The user may interact with the graphical user interface to indicate a magnitude of deviation that is required before an anomaly is detected. In another exemplary embodiment, the predetermined threshold may correspond to an automatically determined threshold that is dynamically adjusted based on business guidelines. For example, the predetermined threshold may be dynamically adjusted to increase or decrease anomaly detection sensitivity during times of increased data flow. The predetermined threshold may be automatically determined and dynamically adjusted by using machine learning techniques consistent with disclosures in the present application.
In another exemplary embodiment, the model may include at least one from among a machine learning model, a statistical model, a mathematical model, a process model, and a data model. The model may also include stochastic models such as, for example, a Markov model that is used to model randomly changing systems. In stochastic models, the future states of a system may be assumed to depend only on the current state of the system.
In another exemplary embodiment, machine learning and pattern recognition may include supervised learning algorithms such as, for example, k-medoids analysis, regression analysis, decision tree analysis, random forest analysis, k-nearest neighbors analysis, logistic regression analysis, 5-fold cross-validation analysis, balanced class weight analysis, etc. In another exemplary embodiment, machine learning analytical techniques may include unsupervised learning algorithms such as, for example, Apriori analysis, K-means clustering analysis, etc. In another exemplary embodiment, machine learning analytical techniques may include reinforcement learning algorithms such as, for example, Markov Decision Process analysis, etc.
In another exemplary embodiment, the model may be based on a machine learning algorithm. The machine learning algorithm may include at least one from among a process and a set of rules to be followed by a computer in calculations and other problem-solving operations such as, for example, a linear regression algorithm, a logistic regression algorithm, a decision tree algorithm, and/or a Naive Bayes algorithm.
In another exemplary embodiment, the model may include training models such as, for example, a machine learning model which is generated to be further trained on additional data. Once the training model has been sufficiently trained, the training model may be deployed onto various connected systems to be utilized. In another exemplary embodiment, the training model may be sufficiently trained when model assessment methods such as, for example, a holdout method, a K-fold-cross-validation method, and a bootstrap method determine that at least one of the training model's least squares error rate, true positive rate, true negative rate, false positive rate, and false negative rates are within predetermined ranges.
In another exemplary embodiment, the training model may be operable, i.e., actively utilized by an organization, while continuing to be trained using new data. In another exemplary embodiment, the models may be generated using at least one from among an artificial neural network technique, a decision tree technique, a support vector machines technique, a Bayesian network technique, and a genetic algorithms technique.
In another exemplary embodiment, an average baseline of the data flow may be determined by capturing a third set of time series data from the data flow based on a third predetermined time period. The third set of time series data may be captured together with subsequent sets of time series data based on a predetermined time period. The third predetermined time period may correspond to the first predetermined time period. Then, consistent with disclosures in the present application, the third set of time series data may be parsed to identify a third key matric. The third key metric may correspond to the first key metric. In another exemplary embodiment, an average key metric may be determined based on the third key metric and the first key metric. The average key metric may relate to an arithmetic mean of the third key metric and the first key metric.
In another exemplary embodiment, the second key metric may be compared with the average key metric in real time to determine a deviation from the average baseline of the data flow. Then, consistent with disclosures in the present application, a normalized anomaly may be identified based on a result of the comparing and the predetermined threshold by using the model.
In another exemplary embodiment, the deviation in the time series data may be confirmed by verifying each of the detected anomalies based on an internal resource. The internal resource may include at least one from among manual reviews of the anomaly as well as third-party data indicating the deviation. Then, an action may be automatically determined for each of the detected anomalies based on a result of the verifying. The action may include at least one from among a manual review action and an automated alerting action. The manual review action may indicate that further manual review of the anomaly may be required.
In another exemplary embodiment, the automated alerting action may include identifying a stakeholder that corresponds to the anomaly. The stakeholder may include at least one from among an internal stakeholder and an external stakeholder such as, for example, the payment processing merchant. Once the stakeholder has been identified, a predetermined preference that corresponds to the stakeholder may be retrieved. The predetermined preference may relate to an alerting subscription. Then, an alert for the stakeholder may be generated based on the predetermined preference. The alert may be generated for a variety of communication channels based on the predetermined preference. The communication channels may include at least one from among an email communication channel, a text message communication channel, a chat communication channel, a telephonic communication channel, as well as a direct communication channel that is integrated with a graphical user interface.
In another exemplary embodiment, generating the alert may further include automatically determining, a recommended procedure to mitigate the anomaly. The recommended mitigation procedure may relate to a recommended course of action to alleviate the effects of the anomaly. Information that relates to at least one from among the anomaly, the first key metric, and the second key metric may also be compiled. Then, the alert may be generated for the stakeholder. The alert may include the recommended mitigation procedure as well as the compiled information.
In another exemplary embodiment, a manual and/or automated feedback loop to modify and/or adjust the monitoring criteria may be implemented by receiving feedback data from the stakeholder. Resulting output data may also be compiled after the anomaly has been identified. The resulting output data may include information that relates to at least one from among the first key metric, the second key metric, the anomaly, and a result of the comparing process. The model may then be updated based on the feedback data and the compiled information.

In a second exemplary use case, a problem statement may indicate that anomalies in a merchant's authorizations evade human detection due to the large number of permutations in features that could be subject to irregularities. The features may include at least one from among client demographics, card attributes, and authorization patterns. By implementing the claimed invention, machine learning time series modeling may be used to quickly identify anomalies and root causes in a merchant's authorization rate and volume at a variety of granularities. The various granularities may include a transaction division, a bank identification number (BIN), a card product, and a transaction type. Early detection may reduce revenue loss resulting from an artificially low authorization rate and improve merchant experience by alerting the merchant of issues in minutes instead of weeks.
Accordingly, with this technology, an optimized process for providing real-time analytics of time series data to identify anomalous data patterns and alert stakeholders is disclosed.
