A Privacy-Preserving Data Mining Method Based on Singular Value Decomposition and Independent Component Analysis

Data Science Journal, 2011
Privacy protection is indispensable in data mining, and many privacy-preserving data mining (PPDM) methods have been proposed. One such method is based on singular value decomposition (SVD), which uses SVD to find unimportant information for data mining ...

Two dimensional singular value decomposition (2D-SVD) based video coding

, 2010
In this paper, we propose a low-complexity video codec based on two-dimensional Singular Value Decomposition (2D-SVD). We exploit the common temporal characteristics of video without resorting to motion estimation.

Information‐Theoretic Framework for Allosteric Communication Pathway Prediction From Protein Structure

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Allosteric communication is fundamental to the function of proteins, but identifying the residue‐level pathways through which signals travel and their directionality is still a major challenge. Here we present a multi‐metric information‐theoretic framework that identifies candidate allosteric communication pathways from a single protein ...

Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

Remote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

Small, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Structural analysis of Helicobacter pylori glutamate racemase in a monoclinic crystal form

Acta Crystallographica Section F, EarlyView.
The crystal structure of H. pylori MurI is reported at 1.43 Å resolution.Glutamate racemase (MurI) catalyzes the stereochemical interconversion of l‐glutamate and d‐glutamate, a key element of bacterial peptidoglycan biosynthesis. In this study, we present the crystal structure of Helicobacter pylori glutamate racemase at 1.43 Å resolution and with ...
