Audio style transfer using shallow convolutional networks and random filters

Abstract: Recently, with the advent of Convolutional Neural Network (CNN) era, Neural style transfer on images has become a very active research topic and the style of an image can be transferred to another image through a CNN so that the image retains both its own content and another style of image. In this work, we propose an algorithm for audio style transfer that uses the force of CNN to generate a new audio from a style audio. We use Continuous Wavelet Transfer(CWT) to convert the audio into a spectrogram and then use the spectrogram as the representation of the audio image through image style transfer method to obtain a new image, and finally, generate an audio using iterative phase reconstruction with Griffin-Lim. We succeed in transferring audio such as light music but had difficulty in transferring audio that has lyrics and high-level metrics such as emotion or tone. We propose several measures to improve the quality of audio and a lot of experimental results shows that our method is better than other methods in terms of sound quality.

Intrinsic ultra-wide completely spin-polarized state realized in a new CrO2 monolayer

Abstract: The high-spin-polarized electronic state has been a central concept in applications such as storage materials and magnetic injection sources. In this work, we predicted the existence of a novel 2D CrO2 lattice, wherein electrons around the Fermi level were indicated to be completely spin-polarized with an ultra-wide energy range. Monte Carlo simulations showed that such an ordered spin state could be maintained to a temperature of 280 K, and further enhanced through strain or hole doping. The predicted structure here inspired us to archive ideal 2D materials as magnetic storage devices or spin injection sources.
