Regarding how to quickly and accurately retrieve the music that users want from huge bulk of music repository, music feature extraction and classification are considered as an important part of music information retrieval and have become a research hotspot in recent years. Traditional music classification approaches use a large number of artificially designed acoustic features. The design of features requires knowledge and in-depth understanding in the domain of music. The features of different classification tasks are often not universal and comprehensive. The existing approach has two shortcomings as follows: ensuring the validity and accuracy of features by manually extracting features and the traditional machine learning classification approaches not performing well on multiclassification problems and not having the ability to be trained on large-scale data. Therefore, this paper converts the audio signal of music into a sound spectrum as a unified representation, avoiding the problem of manual feature selection. According to the characteristics of the sound spectrum, the research has combined 1D convolution, gating mechanism, residual connection, and attention mechanism and proposed a music feature extraction and classification model based on convolutional neural network, which can extract more relevant sound spectrum characteristics of the music category. Finally, this paper designs comparison and ablation experiments. The experimental results show that this approach is better than traditional manual models and machine learning-based approaches.<\/jats:p>","DOI":"10.1155\/2021\/1651560","type":"journal-article","created":{"date-parts":[[2021,5,26]],"date-time":"2021-05-26T21:35:07Z","timestamp":1622064907000},"page":"1-9","source":"Crossref","is-referenced-by-count":40,"title":["Music Feature Extraction and Classification Algorithm Based on Deep Learning"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8128-1016","authenticated-orcid":true,"given":"Jingwen","family":"Zhang","sequence":"first","affiliation":[{"name":"Music and Dance, Xi\u2019an Peihua University, Xi\u2019an Province 710199, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/mmul.2018.023121167"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.2991\/csis-18.2019.25"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/mmul.2017.20"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/ICIS.2017.7960070"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/s11042-020-08836-3"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipm.2020.102270"},{"issue":"2","key":"7","doi-asserted-by":"crossref","first-page":"151","DOI":"10.18290\/rpsych.2019.22.2-4","article-title":"Music emotions and associations in film music listening: the example of leitmotifs from the Lord of the Rings movies","volume":"22","author":"M.
