DOI: 10.1016/j.ifacol.2017.08.719
Abstract: Abstract The steady-state performance of a parametrically or structurally uncertain system can be optimized using iterative real-time optimization methods such as modifier adaptation (MA). Here, we extend a recently proposed MA scheme in two important… read more here.

DOI: 10.1109/lgrs.2022.3193503
Abstract: Tridimensional empirical mode decomposition (TEMD) has been successfully employed as a powerful tool for hyperspectral classification. It achieves good performance to analyze nonlinear/nonstationary data and capture abstract features of hyperspectral images (HSIs). However, the major… read more here.

DOI: 10.1364/ao.428465
Abstract: In order to improve the wavefront distortion correction performance of the classical stochastic parallel gradient descent (SPGD) algorithm, an optimized algorithm based on Nesterov-accelerated adaptive momentum estimation is proposed. It adopts a modified second-order momentum… read more here.
