Abstract

The embodiment of the present invention discloses a machine learning training method, device, server and medium, wherein the method includes: determining the type and initial state of the recognized object, and sending a movement instruction to the mobile device carrying the recognized object; During the moving process of the identified object, the image data of the identified object is collected by the fixed acquisition device according to the set frequency; according to the initial state, moving speed and moving direction of the identified object, and / or the distance between the acquisition device and the identified object Determine the real-time state of the recognized object corresponding to each frame of image data; use the image data of the recognized object as the input value, and use the type and real-time state of the recognized object as the expected output value to perform machine learning training. The embodiment of the present invention solves the problem of low training efficiency caused by manual labeling of training data in the process of machine learning training, improves the efficiency of machine learning training, and reduces labor costs.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a machine learning training method, device, server and medium. Background technique [0002] With the development of artificial intelligence technology, machine learning has been widely used in the field of intelligent driving. For example, in unmanned driving technology, machine learning can be used to identify obstacles during driving, predict the movement status of obstacles, or provide driving navigation. [0003] However, the training data currently used for machine learning needs to be manually labeled. For example, after collecting the sample data, manually label the status of various obstacles in the sample data based on data processing tools, and then perform machine learning training. Especially when the recognition accuracy of obstacles is high, the marking information of obstacles in each state is required to be more detailed and compr...
