Problems solved by technology

However, due to the relatively sparse input data of the model, the optimized objective function degenerates into a non-convex optimization problem, and the result is a local optimal solution, which is also prone to overfitting, resulting in the latent factor There is a large deviation from the actual situation of the user

Abstract

The embodiment of the invention discloses a multimedia data processing method and device. The multimedia data processing method includes the following steps: acquiring data information of first multimedia data corresponding to a target use identification based on a multimedia interaction application; adopting an RBM model, and acquiring data information of second multimedia data corresponding to the target user identification according to the data information of the first multimedia data corresponding to the target user identification; and outputting the second multimedia data corresponding to the target user identification according to the data information of the second multimedia data corresponding to the target user identification, wherein the first multimedia data is operated multimedia data, and the second multimedia data is not operated. The multimedia data processing method and device can restore original input data to the greatest extent, and can improve the stability of a solution result.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multimedia data processing method and equipment thereof. Background technique [0002] Collaborative filtering is widely used in the field of music personalization to mine users' preferences for songs, but the nearest neighbor collaborative filtering method based on Item-Based and User-Based is only used to compare and observe the flow of listening to songs and operations in a shallow level. Data, and then display similar preferences of users, it is impossible to mine deep user relationship data, that is, it is impossible to obtain the latent factors inside the data. [0003] Using the collaborative filtering method of Singular Value Decomposition (SVD), the User-Item matrix can be decomposed into two small matrices by using the matrix decomposition technology, and each small matrix corresponds to the latent feature vector matrix of the user and the item. , so as to find the...
