Adaptive IIR Filtering Using QR Matrix Decomposition

, 1995
In this paper an approach to adaptive IIR filtering based on a pseudo-linear regression and applying an iterative QR matrix decomposition is developed. In simulations, the algorithm has shown a high stability and excellent convergence properties.

Principal component analysis using QR decomposition

, 2013
In this paper we present QR based principal component analysis (PCA) method. Similar to the singular value decomposition (SVD) based PCA method this method is numerically stable.

ECG‐TransCovNet: A hybrid transformer model for accurate arrhythmia detection using Electrocardiogram signals

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.

M3LoRA: Flexible Task Adaptation via Multiple Low‐Rank Matrices With Mixture‐of‐Subspaces and Minor Singular Components Initialization

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Parameter‐efficient fine‐tuning (PEFT) has become a crucial paradigm for domain adaptation, achieving strong performance by updating only a small fraction of model parameters. Among various PEFT methods, low‐rank adaptation (LoRA) is widely adopted due to its structural simplicity and computational efficiency.

State of health estimation for lithium‐ion batteries using modern heuristic algorithm optimized multiple kernel extreme learning

Energy Conversion and Economics, EarlyView.
Abstract Accurate state of health (SOH) estimation is crucial for the safe operation of lithium‐ion batteries. To address the limited capability of traditional models in characterizing nonlinear degradation, this study proposes a novel data‐driven SOH estimation framework.

Too Much of a Good Thing? Striking a Balance Between Research Environment Inputs and Research Output Quality in UK Business Schools

British Journal of Management, EarlyView.
Abstract The UK's Research Excellence Framework (REF) is one of the world's most established performance‐based research funding systems, shaping universities’ strategic choices. While the REF emphasizes investing in research inputs to enhance output quality, the investments in research environment inputs can, at some point, become counterproductive and

Image encryption based on feedback control discrete switching hyperchaotic system and QR decomposition

AIP Advances
A two-dimensional switching-controlled hyperchaotic system has been developed that enhances the randomness of the system through dynamic switching of the control parameter. The proposed hyperchaotic system is then applied to image encryption.

Determining the utility of radio frequency identification (RFID) technology for disaster victim identification (DVI)

Journal of Forensic Sciences, EarlyView.
Abstract Radio frequency identification (RFID) technology was evaluated as a method for electronically tracking human remains and associated identifying information during mass fatality incidents. Conventional tags are prone to physical damage and failure, which can compromise identification processes and hinder the repatriation of bodies.
