Description
TECHNICAL FIELD

This disclosure relates to the field of artificial intelligence (AI), and in particular, to an AI processing method and apparatus.


BACKGROUND

AI is a new technology science for researching and developing a theory, a method, a technology, and an application system for simulating, extending, and expanding human intelligence. AI processing may be performed by using an AI technology on an intelligent electronic device (such as a smartphone or a smart TV), to simulate and implement human intelligence in different scenarios. For example, the AI technology may be used to implement mobile phone object recognition software, reverse image search software, smart TV object recognition software, and the like, so as to provide an intelligent service based on a recognition result, to improve intelligent user experience.


An AI processing process includes training and inference. The training is to use massive data as an input to train a deep neural network model. The inference is to input to-be-determined data into a trained deep neural network model, to “infer” various conclusions as AI processing results. For example, AI processing may identify people, objects, or scenarios in data. Content of the AI processing results varies in different scenarios. For example, for object recognition software, the AI processing result may be annotation information (such as a physical name or an attribute) of a recognized object. For example, for advertisement push software, the AI processing result may be advertisement push content.


Currently, one AI processing process is request-response, for example, a process of image recognition in a smartphone. In the AI processing scenario shown in FIG. 1, a smartphone generates an image (the image may come from a camera of the phone or be downloaded from another channel). The smartphone sends the image to a server by using a network, and the server performs AI processing and sends a result obtained after the AI processing to the smartphone for display. The AI processing process is a typical request-response process. In a server AI processing phase, the smartphone is waiting for the result and cannot perform real-time AI processing on a data stream.


Another AI processing process is that the electronic device performs AI processing. The electronic device has an AI processing capability, and may perform AI processing in real time. This solution can process a data stream in real time, but has a high requirement on the electronic device.


Still another AI processing process is that, in a scenario in which an Intelligent EdgeSite is deployed between the server and the electronic device, the Intelligent EdgeSite performs AI processing. In the intelligent video surveillance scenario shown in FIG. 1a, an intelligent camera synchronizes an image data stream to an Intelligent EdgeSite in real time, and the Intelligent EdgeSite performs AI processing, and directly displays an AI processing result to a user or returns the result to the camera for display. In this solution, AI processing is performed on a data stream in real time. However, this solution is applicable only to real-time surveillance scenarios. Edge intelligent nodes need to be deployed, which is costly and difficult to deploy on a large scale.


Therefore, how to implement low-cost real-time data stream AI processing through easy deployment without requiring a device capability becomes an urgent problem to be resolved.

In the embodiments of this application, the word such as “example” or “for example” is used to represent giving an example, an illustration, or a description. Any embodiment or design scheme described as an “example” or “for example” in the embodiments of this application should not be explained as being more preferred or having more advantages than another embodiment or design scheme. Exactly, use of the word “example” or “for example” or the like is intended to present a related concept in a specific manner.


For ease of understanding, terms in this application are explained first.


A data stream may be a data set sent to a computing device, and the data stream may include but is not limited to one or more of the following content: a video stream, an image stream, a text stream, and the like.


A content distribution server may be a server that provides the data stream for the computing device. The data stream may be a service data stream or another data stream. This is not specifically limited in the embodiments of this application. The content distribution server may provide the data stream for the computing device according to a rule or according to a request of the computing device.


A cloud server may be a server deployed on cloud to implement a centralized service.


The computing device may be a data stream requirement device. After obtaining the data stream, the computing device may display the data stream or perform corresponding processing.
