Variable Forgetting Factor LS Algorithm for Polynomial Channel Model [PDF]

open access: yesInternational Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Variable forgetting factor (VFF) least squares (LS) algorithm for polynomial channel paradigm is presented for improved tracking performance under nonstationary environment. The main focus is on updating VFF when each time‐varying fading channel is considered to be a first‐order Markov process.

Absolute finite differences based variable forgetting factor RLS algorithm

open access: yesIET Signal Processing, Volume 16, Issue 1, Page 80-91, February 2022., 2022
Abstract Adaptive signal processing requires an efficient non‐stationarity detector. Most of the known non‐stationarity detection algorithms are based on residual statistics. The study proposes a novel non‐stationarity detection algorithm based on finite differences analysis of the processed signal.

Regularized Least Squares Recursive Algorithm with Forgetting Factor for Identifying Parameters in the Grinding Process

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
This paper investigates a parameter identification problem in the grinding process. Due to the data saturated phenomenon and the ill‐posed of parameter identification inverse problem, this paper presents a regularized least squares recursive algorithm with a forgetting factor (RLSRAFF), the basic idea of which is to combine the forgetting factor with ...

A new recursive algorithm for time-varying autoregressive (TVAR) model estimation and its application to speech analysis [PDF]

open access: yes, 2012
This paper proposes a new state-regularized (SR) and QR decomposition based recursive least squares (QRRLS) algorithm with variable forgetting factor (VFF) for recursive coefficient estimation of time-varying autoregressive (AR) models.

A New Penalized Recursive Least Squares Method With a Variable Regularization Factor for Adaptive Sparse Filtering

open access: yesIEEE Access, 2018
A new cost function that introduces the minimum-disturbance (MD) constraint into the conventional recursive least squares (RLS) with a sparsity-promoting penalty is first defined in this paper.

Late Amazonian Ice Survival in Kasei Valles, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 125, Issue 11, November 2020., 2020
Abstract High‐obliquity excursions on Mars are hypothesized to have redistributed water from the poles to nourish mid‐latitude glaciers. Evidence of this process is provided by different types of viscous flow features (ice‐rich deposits buried beneath sediment mantle) located there today, including lobate debris aprons (LDAs).
