Abstract: For the conjugate gradient method to solve the unconstrained optimization problem, given a new interval method to obtain the direction parameters, and a new conjugate gradient algorithm is ...
It is our pleasure to introduce the Research Topic on advances in noise reduction and feature extraction of acoustic signals in Frontiers in physics. Acoustic signal processing and its analysis is one ...
Least-squares reverse-time migration (LSRTM) can overcome the problems of low resolution and unbalanced amplitude energy of deep formation imaging in reverse-time migration (RTM); hence, it can obtain ...
Abstract: The phase-only null beamforming synthesis is widely used in communication, radar, and sonar. Due to the phase-only constraint (constant modulus constraint), the problem is nonconvex and ...
This article is about the gradient descent algorithm and the different alternatives that can be used instead of the gradient descent algorithm. Gradient descent is a popular optimisation technique in ...
