Problems solved by technology

In related technologies, it is possible to determine whether the audios belong to the same audio through the feature vector of the audio, and then complete the cover retrieval task. However, due to the variety of audio changes, it is very difficult to judge whether the audios belong to the same audio. Therefore, how to improve The discriminability of audio feature vectors is an urgent technical problem to be solved

Abstract

The invention relates to a feature coding model generation method, an audio determination method and a related device. The feature coding model generation method comprises the following steps: acquiring a plurality of sample audios marked with category labels; extracting audio features of the plurality of sample audios; encoding the audio features of the plurality of sample audios through a feature encoding model to obtain a plurality of encoding vectors of the plurality of sample audios, and classifying the plurality of sample audios according to the plurality of encoding vectors to obtain category predicted values of the plurality of sample audios; and determining a target loss value of the target loss function according to the plurality of coding vectors, the category prediction values of the plurality of sample audios and the category labels of the plurality of sample audios, and updating parameters of the feature coding model based on the target loss value to obtain a trained feature coding model. The trained feature coding model obtained by the feature coding model generation method can improve the identifiability of the feature vector of the audio output and the robustness of the feature coding model.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular, to a method for generating a feature coding model, a method for determining audio, and related devices. Background technique [0002] Music works usually contain very rich elements, such as rhythm, melody, harmony, etc., presenting a multi-level internal structure. Therefore, very rich changes can be introduced into the cover of a musical work, making the musical work change in multiple aspects such as pitch, timbre, speed, structure, melody and lyrics. In related technologies, it is possible to determine whether the audios belong to the same audio through the feature vector of the audio, and then complete the cover retrieval task. However, due to the variety of audio changes, it is very difficult to judge whether the audios belong to the same audio. Therefore, how to improve The discriminability of audio feature vectors is an urgent technical problem ...
