DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. The described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

FIG. 1 is a flowchart of Embodiment 1 of a method for processing lifelong learning of a terminal according to the present disclosure. As shown in FIG. 1, the method in this embodiment may include the following steps:

Step 101: Send, to a server, a request for downloading a function module, where the download request includes description information of the function module.

Step 102: Receive the function module that is sent by the server and is corresponding to the description information.

Step 103: Use the function module to expand and/or update a local function.

When the terminal has a new function requirement, the terminal may send, according to the function requirement of the terminal, a request that includes description information of a corresponding function module to the server, so as to request to download the function module. Alternatively, the terminal may be set to periodically send a download request that includes description information of a corresponding function module to the server. The description information of the function module may be information that is used to describe the function module, such as a name of the function module and a type of the function module. The terminal receives the function module that is sent by the server and is corresponding to the description information, and uses the downloaded function module to expand a local function or update an existing local function module, so that the terminal has a capability of lifelong learning, such as user behavior analysis and image recognition. In addition to acquiring an updated function module from a server side, the terminal may further independently update the function module according to data collected by the terminal, so as to improve intelligence of the terminal.

Further, before the sending, to a server, a request for downloading a function module, the method further includes sending a retrieval query request to the server after a task is created, where the retrieval query request includes task requirement information; and receiving a retrieval result sent by the server, where the retrieval result includes the description information that is of the function module and is corresponding to the task requirement information; and after the using the function module to expand and/or update a local function, the method further includes using an expanded and/or updated local function to process the task.

After a task is created according to a function requirement, to query a function module related to the function requirement of the terminal, the terminal may send a retrieval query request to the server to determine whether the server has the corresponding function module; if yes, the terminal may further acquire description information of the function module from a retrieval result that is fed back by the server, where the description information is used by the terminal to send, to the server, a request for downloading the function module. After downloading the function module, the terminal uses the function module to complete expansion and/or updating of a local function, and uses an expanded and/or updated local function to process the task. For example, a smartphone does not have a personalized recommendation function that matches a user of the smartphone, or a personalized recommendation function module in the smartphone needs to be updated; the smartphone may send a keyword “recommendation” to a server to perform retrieving and querying, so as to retrieve and query a function module related to recommendation; the smartphone receives a retrieval result sent by the server, where the retrieval result includes a name and a corresponding type of such a function module. The terminal downloads the function module locally and uses the function module to implement a function of recommending a movie, a book, music, or the like to the user of the smartphone.

Further, after the using an expanded and/or updated local function to process the task, the method further includes feeding back operating data obtained after the task processing to the server, so that the server updates the function module according to the task and the operating data corresponding to the task.

The terminal uses the expanded and/or updated local function to process the task; in a process of processing the task, the terminal needs to provide the operating data of the function module accordingly; the terminal may upload the operating data to the server after processing the task, so that the server updates the function module according to the task and the operating data corresponding to the task. The function module that is updated using the operating data uploaded by the terminal to the server is more pertinent to the terminal.

In this embodiment, a terminal sends, to a server, a retrieval query request and a request for downloading a function module, and uses the downloaded function module to expand and/or update a local function; in addition, the function module on a server side may further be updated using operating data that is obtained after task processing and uploaded by the terminal to the server, which resolves a problem in the prior art that the terminal cannot perform function expansion and/or updating, and implements that the terminal has a capability of lifelong learning.

FIG. 2 is a flowchart of Embodiment 2 of a method for processing lifelong learning of a terminal according to the present disclosure. As shown in FIG. 2, the method in this embodiment may include the following steps:

Step 201: Receive a request that is sent by the terminal and for downloading a function module, where the download request includes description information of the function module.

Step 202: Send the function module corresponding to the description information to the terminal, so that the terminal uses the function module to expand and/or update a local function.

A server sends the function module corresponding to the description information to the terminal according to the description information, of the function module, included in the request that is sent by the terminal and for downloading the function module, so that the terminal expands and/or updates the local function.

Further, before the receiving a request that is sent by the terminal and for downloading a function module, the method further includes creating the function module according to a task and operating data corresponding to the task; and storing a correspondence between the function module and the description information of the function module.

The server needs to create the function module according to the task and the operating data corresponding to the task, where the function module is an initial function module. The initial function module may be created using a lifelong learning algorithm, such as classification, clustering, regression, and a rule. A type of the function module may be determined according to the task, which is correspondingly to establish an entire model, a group model, an individual model, or the like. The function module obtained by means of learning is stored in a function module library using an index. The index corresponds to the description information of the function module. To store and retrieve large number of function modules, data structures of different types of function modules need to be analyzed, so as to separately index the function modules effectively. For example, a dense vector, a sparse vector, and a tree-like classifier need different indexing mechanisms, so that retrieval is performed according to an id, a group, and a similarity. Storage of the function module used in this embodiment relates to storage and retrieval of a large scale of dense vectors, sparse vectors, trees, and pictures. The dense vectors relate to a method such as KDTree, ConeTree, and BBTree; the sparse vectors relate to a method such as an inverted table, PPJoin, and Spilltree. For a function module in a form of a tree, the tree may be converted into a rule, and then a character string is used to match the rule; or the tree may be regarded as a simple picture, and then matching is directly performed on the picture. The function module corresponds to a result model obtained after statistics collecting and lifelong learning by a server side, and is used by a client to complete a function such as intelligent prediction.

It should be noted that this embodiment sets no limitation on specific implementation of function module creation and storage.

Further, after the storing a correspondence between the function module and the description information of the function module, the method further includes receiving the task and the operating data corresponding to the task that are sent by the terminal; and updating the function module according to the task and the operating data.

The server may update the function module according to the task and the operating data corresponding to the task that are sent by the terminal; for the same task, the data may increase in batches as time passes, or may be fed back by the terminal to the server once and for all. An update algorithm of the function module is obtained by means of statistics collecting and lifelong learning. For example, updating of a function module corresponding to a same task may be completed by means of online learning; updating of function modules corresponding to different tasks may be completed by means of transfer learning. Mechanisms that include multi-task learning, lifelong learning, and the like may also be used to complete updating of a function module. Statistics collecting and lifelong learning may include related statistics collecting and a lifelong learning algorithm, for example, k-means, svm, Naive Bayes, and a decision tree. Methods related to transfer learning may include methods such as multi-task-based learning and TrAdaboost. Lifelong learning may include deep learning, an ELLA algorithm, and the like. The function module is increasingly accurate and intelligent after being updated using a lifelong learning mechanism. It should be noted that this embodiment sets no limitation on specific implementation of function module updating.

Further, before the receiving a request that is sent by the terminal and for downloading a function module, the method further includes receiving a retrieval query request sent by the terminal, where the retrieval query request includes task requirement information; and sending a retrieval result to the terminal, where the retrieval result includes the description information that is of the function module and is corresponding to the task requirement information.

The server receives the retrieval query request sent by the terminal, and sends, to the terminal, the description information that is of the function module and is corresponding to the task requirement information retrieved by the terminal. The description information of the function module may be information that is used to describe the function module, such as a name of the function module and a type of the function module.

In this embodiment, a server creates a function module according to a task and operating data corresponding to the task, stores the function module in a function module library, updates the function module according to the task and the operating data corresponding to the task, receives a retrieval query request and a download request that are sent by a terminal, and sends a corresponding function module to the terminal, so that the terminal uses the function module to expand and/or update a local function, which implements that the terminal has a capability of lifelong learning, and resolves a problem in the prior art that the terminal cannot perform function expansion and/or updating.
