Abstract

The invention provides a video label definition model construction method and system, electronic equipment and a storage medium, and the method comprises the following steps: a video feature obtaining step: obtaining video features of a video for model training, and aggregating the video features; an audio feature acquisition step: acquiring audio features of the video, and aggregating the audio features; a video representation obtaining step, wherein a representation vector of the video is obtained according to the aggregated video features and the aggregated audio features; and a definition model construction step: constructing a video label definition model through back propagation according to the representation vector. The video label definition method solves the problems that an existing video label definition method is not flexible enough in feature integration mode, poor in interactivity of different features and poor in coping with the situation of class imbalance.

Description

technical field [0001] The invention belongs to the field of machine learning, and in particular relates to a video label definition model construction method, system, electronic equipment and storage medium. Background technique [0002] In the era of widespread application of multimedia technology, image and video-type multimedia materials are emerging in daily life. On some short video websites, users will upload a large number of self-made videos. These videos have no tags, so they can be automatically given The technology of video tagging is particularly important. [0003] Existing techniques for video label definition include simple feature aggregation, feature aggregation via recurrent neural networks, and feature aggregation via high-dimensional convolutional networks. However, the defect of the existing technology is that simply using the pooling method to aggregate features is relatively simple, without considering the context of each frame of video, and cannot c...
