Recognition and Error Correction Techniques for Piano Playing Music Based on Convolutional Cyclic Hashing Method

Abstract

Music as a sound symbol can express what people think; music is both a form of social behavior and can promote people’s emotional communication; music is also a form of entertainment and can enrich people’s spiritual life. In this paper, we propose a new convolutional recurrent hashing method CRNNH, which uses multilayer RNN to learn to discriminate piano playing music using convolutional feature map sequences. Firstly, a convolutional feature map sequence learning preserving similarity hash function is designed consisting of multilayer convolutional feature maps extracted from multiple convolutional layers of a pretrained CNN; secondly, a new deep learning framework is proposed to generate hash codes using a multilayer RNN, which directly uses the convolutional feature maps as input to preserve the spatial structure of the feature maps; finally, a new loss function is proposed to preserve the semantic similarity and balance of the hash codes, while considering the quantization error generated when the hash layer outputs binary hash codes. The experimental results illustrate that the proposed CRNNH can obtain better performance compared to other hashing methods.

Musical Note Feature Recognition Based on Long Short-Term Memory

“…In the eld of music creation, many composers use some note feature speech recognition software to automatically recognize the features of notes. Notes are used not only for learning music, but also for searching and classifying songs according to the recognition of notes, which promotes the diversi ed development of music [1]. If they can automatically recognize the music they play by computer and nish the music score creation automatically, it will greatly improve their creative e ciency, greatly stimulate creative inspiration, and change the inconvenience of writing music scores by hand at present.…”
