Abstract

The invention relates to a video classification method and device, equipment, a medium and a product, and relates to the technical field of computers, and the method comprises the steps: generating a first-class classification result of a first-class video based on a classification network, and generating a second-class classification result of a second-class video based on the classification network; wherein the first type of video belongs to a first video set, the second type of video belongs to a second video set, and the video number of the first video set is greater than that of the second video set; determining a first loss function between the first-class video tag and the first-class classification result, and determining a second loss function between the second-class video tag and the second-class classification result; and training a classification network based on the first loss function and the second loss function, and classifying the target second-class videos to be classified based on the trained classification network. In this way, the classification precision of the classification network for the second-class videos with the small sample size can be improved.

Description

technical field [0001] The present disclosure relates to the field of computer technologies, and in particular, to a video classification method, a video classification apparatus, an electronic device, a computer-readable storage medium, and a computer program product. Background technique [0002] In the video / short video platform, videos uploaded by users, businesses, media and other parties are usually received, and it is very important to classify the received massive videos. The classification results obtained by classifying the videos can be helpful for personalized recommendation of videos, displaying corresponding videos in corresponding partitions, and conducting research on user preferences according to the classification results of videos. At present, the classification method of video usually relies on the classification network, which can learn the relationship between its own parameters and their labels in one or more dimensions, such as the image frame of the ...
