, 2016 The application of Partial Membership Latent Dirichlet Allocation(PM-LDA) for hyperspectral endmember estimation and spectral unmixing is presented. PM-LDA provides a model for a hyperspectral image analysis that accounts for spectral variability and ...

Modelling Grocery Retail Topic Distributions: Evaluation, Interpretability and Stability [PDF]
, 2020 Understanding the shopping motivations behind market baskets has high commercial value in the grocery retail industry. Analyzing shopping transactions demands techniques that can cope with the volume and dimensionality of grocery transactional data while

Transition state method and Wannier functions [PDF]
, 2005 We propose a computational scheme for materials where standard Local Density Approximation (LDA) fails to produce a satisfactory description of excitation energies. The method uses Slater's "transition state" approximation and Wannier functions basis set.

Advanced Sensor Research, EarlyView.This study introduces a textile‐based capacitive pressure sensor featuring a triangular prism microstructure, which significantly enhances sensitivity to 5.52% kPa−¹ and supports a wide sensing range up to 330 kPa. The sensor's performance is validated in a 4‐channel capacitive pressure‐based force myography (cFMG) armband for gesture recognition ...

Modeling Word Relatedness in Latent Dirichlet Allocation [PDF]
arXiv, 2014 Standard LDA model suffers the problem that the topic assignment of each word is independent and word correlation hence is neglected. To address this problem, in this paper, we propose a model called Word Related Latent Dirichlet Allocation (WR-LDA) by incorporating word correlation into LDA topic models.

Advanced Therapeutics, EarlyView.Cold plasma devices (J‐Plasma, Piezo Brush PZ3, Plasma Care) generate unique reactive species that penetrate tissues differently, enabling biofilm eradication while preserving tissue health. This study uncovers plasma‐device interactions with biofilms and surfaces, highlighting tailored applications for precision medicine and infection control ...

On the nature of amorphous polymorphism of water
, 2005 We report elastic and inelastic neutron scattering experiments on different amorphous ice modifications. It is shown that an amorphous structure (HDA') indiscernible from the high-density phase (HDA), obtained by compression of crystalline ice, can be ...

Linear and Quadratic Discriminant Analysis: Tutorial [PDF]
arXiv, 2019 This tutorial explains Linear Discriminant Analysis (LDA) and Quadratic Discriminant Analysis (QDA) as two fundamental classification methods in statistical and probabilistic learning. We start with the optimization of decision boundary on which the posteriors are equal. Then, LDA and QDA are derived for binary and multiple classes.

Advanced Theory and Simulations, EarlyView.Binding energy and electronic structure calculations are used to assess the ability of metal–organic framework (MOF)‐TiO2 composite materials to detect volatile organic compounds found in human breath. Electronic structure changes are measured by comparing density of states profiles using Wasserstein distances.

Potential economic impacts of achieving good environmental status in Black Sea fisheries
Ecology and Society, 2014 The Marine Strategy Framework Directive (MSFD) mandates that European Union (EU) member states achieve Good Environmental Status (GEnS) based on an ecosystem-based approach to management. For commercial fisheries, the primary target under the MSFD is one
