Performance Analysis of the Gradient Comparator LMS Algorithm

no code implementations10 May 2016 Bijit Kumar Das, Mrityunjoy Chakraborty

The sparsity-aware zero attractor least mean square (ZA-LMS) algorithm manifests much lower misadjustment in strongly sparse environment than its sparsity-agnostic counterpart, the least mean square (LMS), but is shown to perform worse than the LMS when sparsity of the impulse response decreases.

Adaptive Combination of l0 LMS Adaptive Filters for Sparse System Identification in Fluctuating Noise Power

no code implementations10 May 2016 Bijit Kumar Das, Mrityunjoy Chakraborty

Recently, the l0-least mean square (l0-LMS) algorithm has been proposed to identify sparse linear systems by employing a sparsity-promoting continuous function as an approximation of l0 pseudonorm penalty.

Sparse Distributed Learning via Heterogeneous Diffusion Adaptive Networks

no code implementations26 Oct 2014 Bijit Kumar Das, Mrityunjoy Chakraborty, Jerónimo Arenas-García

In-network distributed estimation of sparse parameter vectors via diffusion LMS strategies has been studied and investigated in recent years.
