Short video automatic labeling method based on feature and multi-label enhanced representation

Abstract

The invention discloses a short video automatic labeling method based on feature and multi-label enhanced representation, which comprises the following steps: reconstructing an original feature matrixby using a dictionary mapping matrix, a product of public low-rank representation and a sparse error matrix to form a multi-view low-rank representation item; clustering an overall data set to obtainall data sets and potential label correlation information in different clusters to form global and local label correlation learning items; taking the common low-rank representation as a prediction label, subtracting the prediction label from a real label to obtain a labeling error, and minimizing the labeling error to form a minimized labeling error term; and weighting the multi-view low-rank representation item, the global and local label correlation learning item and the minimized labeling error item to obtain a total target function, optimizing the total target function by using an alternating direction multiplier method, introducing a Lagrange multiplier, and sequentially iteratively updating each matrix variable until the value of the target function converges to obtain a final labeling result. According to the method, the accuracy in the short video multi-label labeling problem is improved.

Description

technical field [0001] The present invention relates to the field of short videos, in particular to a short video automatic labeling method based on feature and multi-label enhanced representation. Background technique [0002] At present, with the changes in the working and living environment and the rapid popularization of mobile phone networks, people's way of receiving information has gradually changed from traditional long-term reception to fragmented reception. People are no longer limited to simply reading and creating for a long time, but obtain the information they want in a short period of time through mobile phone networks and other means at any time. In this context, short videos emerged as the times require. [0003] As an emerging media form, short videos are widely spread on major online social platforms, and have achieved rapid development in recent years. Major short video network platforms allow users to make, process, and upload short videos that are ofte...
