Adaptive Kalman Filtering Developed from Recursive Least Squares Forgetting Algorithms

no code implementations16 Apr 2024 Brian Lai, Dennis S. Bernstein

KFLS is an extension of generalized forgetting recursive least squares (GF-RLS), a general framework which contains various extensions of RLS from the literature as special cases.

Efficient Batch and Recursive Least Squares for Matrix Parameter Estimation with Application to Adaptive MPC

no code implementations16 Apr 2024 Brian Lai, Dennis S. Bernstein

Traditionally, batch least squares (BLS) and recursive least squares (RLS) are used for identification of a vector of parameters that form a linear model.

Convergence of Recursive Least Squares Based Input/Output System Identification with Model Order Mismatch

no code implementations16 Apr 2024 Brian Lai, Dennis S. Bernstein

Next, this work analyzes online identification of input/output models in the case where the order of the identified model is higher than that of the true system.

SIFt-RLS: Subspace of Information Forgetting Recursive Least Squares

no code implementations16 Apr 2024 Brian Lai, Dennis S. Bernstein

This paper presents subspace of information forgetting recursive least squares (SIFt-RLS), a directional forgetting algorithm which, at each step, forgets only in row space of the regressor matrix, or the \textit{information subspace}.

Generalized Forgetting Recursive Least Squares: Stability and Robustness Guarantees

no code implementations8 Aug 2023 Brian Lai, Dennis S. Bernstein

This work present generalized forgetting recursive least squares (GF-RLS), a generalization of recursive least squares (RLS) that encompasses many extensions of RLS as special cases.

Nonlinear Trajectory-Based Region of Attraction Estimation for Aircraft Dynamics Analysis

no code implementations16 Jun 2021 Brian Lai, Torbjørn Cunis, Laurent Burlion

A piecewise polynomial model of the GTM is used to simulate trajectories and the developed analysis tools are used to estimate the ROA around a trim condition based only on this trajectory data.

Regularization-Induced Bias and Consistency in Recursive Least Squares

no code implementations16 Jun 2021 Brian Lai, Syed Aseem Ul Islam, Dennis S. Bernstein

Within the context of recursive least squares (RLS) parameter estimation, the goal of the present paper is to study the effect of regularization-induced bias on the transient and asymptotic accuracy of the parameter estimates.

ErrorNet: Learning error representations from limited data to improve vascular segmentation

no code implementations10 Oct 2019 Nima Tajbakhsh, Brian Lai, Shilpa Ananth, Xiaowei Ding

In this paper, we propose a segmentation framework called ErrorNet, which learns to correct these segmentation mistakes through the repeated process of injecting systematic segmentation errors to the segmentation result based on a learned shape prior, followed by attempting to predict the injected error.
