A wavelet is a small localized wave based on a mathematical function. Wavelet analysis is able to represent signals in the time and frequency domains at the same time. Many modern applications have ...

An unsupervised anomaly detection system for identifying gravitational wave signals in LIGO detector noise using Continuous Wavelet Transform (CWT) and Long Short-Term Memory (LSTM) autoencoders.

Abstract: In this paper, we propose a new type of continuous wavelet transform. However we discretize the variables of integral a and b, any numerical integral has a high resolution and a does not ...

The experimental ultrasound data is always trained by measurement errors, internal and external noise. For this reason, it is always necessary to apply some signal processing operations, such as ...
