Complex-valued neural networks for machine learning on non-stationary physical data

نویسندگان

چکیده

Deep learning has become an area of interest in most scientific areas, including physical sciences. Modern networks apply real-valued transformations on the data. Particularly, convolutions convolutional neural discard phase information entirely. Many deterministic signals, such as seismic data or electrical contain significant signal. We explore complex-valued deep to leverage non-linear feature maps. Seismic commonly a lowcut filter applied, attenuate noise from ocean waves and similar long wavelength contributions. In non-stationary data, content can stabilize training improve generalizability networks. While it been shown that be restored networks, we show how maps improves both inference Furthermore, smaller complex outperform larger

On Complex Valued Convolutional Neural Networks

Convolutional neural networks (CNNs) are the cutting edge model for supervised machine learning in computer vision. In recent years CNNs have outperformed traditional approaches in many computer vision tasks such as object detection, image classification and face recognition. CNNs are vulnerable to overfitting, and a lot of research focuses on finding regularization methods to overcome it. One ...

Novel Complex Valued Neural Networks

In view of many applications, in recent years, there has been increasing interest in complex valued neural networks. In this paper, it is reasoned that transforming real valued signals into complex valued signals (using Discrete Fourier Transform) and processing them in that domain is equivalent to processing real valued signals. This approach could have many advantages. Also neural networks ba...
