Researchers have developed a compact, low-cost convolutional spectrometer that delivers lab-grade precision for applications ...

This article is about the wavelet transform, which is used as a tool for frequency analysis of signals. Among them, I will explain the Gabor/Morlet wavelet in the context of the Continuous Wavelet ...

A differentiable fractional Fourier transform (FRFT) implementation with layers that can be trained end-to-end with the rest of the network. This package provides implementations of both fast ...

PFFFT does 1D Fast Fourier Transforms, of single precision real and complex vectors. It tries do it fast, it tries to be correct, and it tries to be small. Computations do take advantage of ...

At the Hong Kong University of Science and Technology in Guangzhou, students can listen to lectures given by AI avatars that ...

There are points in time at which a well-known technology, which has been used and gradually improved for decades, reaches its physical limitations, forcing a shift towards dramatically different ...
