融合LSTM和注意力机制的音乐分类推荐方法

Music Classification and Recommendation Method Combining LSTM and AM

摘要: 针对音乐资源过于庞大，现有的音乐推荐方法分类准确度不高，对用户情感的识别较模糊导致人们在生活中难以寻找到偏好音乐的问题，本文提出一种将长短期记忆神经网络(Long Short-Term Memory, LSTM)与注意力机制(Attention Model, AM)相融合的音乐分类及推荐方法，该方法由音乐分类模型和音乐推荐模型两部分组成。首先对音频数据的声学特征进行捕获，构成含有多维特征的序列后，通过LSTM神经网络和注意力机制对音乐进行情感分类，接下来采集用户的历史收听记录，选取最近的十首歌曲并生成频谱图，结合CNN (Convolutional Neural Networks, CNN)对用户当前情感进行识别，提升推荐的高效性。实验部分将新提出的模型与其他传统音乐分类模型进行多组对比测试，结果显示与近年来现存的模型相比，新提出的模型明显提升了情感判断及用户情感识别的准确度，音乐推荐的准确度有所增强。

Abstract: In view of the huge amount of music resources, the existing music recommendation methods have low classification accuracy, fuzzy recognition of user emotions, and low concentration of target data analysis, which makes it difficult to satisfy people’s preference for music in daily life. Due to demand and other issues, a music classification and recommendation method combining Long Short-Term Memory and Attention Model is proposed. The method consists of a music classification model and a music classification model. The recommended model consists of two parts. First to capture audio data of various acoustic characteristics, constitute a sequence containing multidimensional characteristics, through the LSTM Neural network classification of music emotion and attention mechanism; the next, gathering user history to record, select its most recent ten songs and generate the spectrum diagram, combined with CNN (Convolutional Neural Networks, CNN) to accurately identify the user’s current emotion, recommend the efficiency of ascension. The experimental part com-pares the new model with other traditional music classification models, and the results show that compared with the existing models in recent years, the new model significantly improves the accuracy of emotion judgment and user emotion recognition, and the accuracy of music recommendation is enhanced to some extent.
