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

متن کاملComplex-Valued Neural Networks
The usual real-valued artificial neural networks have been applied to various fields such as telecommunications, robotics, bioinformatics, image processing and speech recognition, in which complex numbers (two dimensions) are often used with the Fourier transformation. This indicates the usefulness of complex-valued neural networks whose input and output signals and parameters such as weights a...
متن کاملOn 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 ...
متن کاملNovel 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...
