Peak aggregation as an innovative strategy for improving the predictive power of LC-MS metabolomic profiles.

TL;DR: This technical note proposes a new strategy based on the application of the so-called peak aggregation methods (NMF Reduction, PCA Decomposition, Maximum Peak, and Spectrum Mean) to take advantage of the variable collinearity and solve the issue of high variable collInearity.
Journal ArticleDOI

Data Simulation in Machine Olfaction with the R Package Chemosensors

TL;DR: This work proposes software for performing data simulations in the machine olfaction field by generating parameterized sensor array data, and introduces the concept of a virtual sensor array which can be used as a data generation tool.
Journal ArticleDOI

Multiview: a software package for multiview pattern recognition methods

TL;DR: Multiview extensions of four well-known pattern recognition methods are proposed here, including multiview t-distributed stochastic neighbour embedding,multiview multidimensional scaling, and multivView minimum curvilinearity embedding as well as a multivview spectral clustering method.
Proceedings ArticleDOI

Predictability of protein subcellular locations by pattern recognition techniques

TL;DR: An analysis of the predictability of subcellular locations is performed by using simple pattern recognition techniques in an attempt to capture the real dimensions of the problem at hand.
Journal ArticleDOI

#CoronavirusCruise: Impact and implications of the COVID-19 outbreaks on the perception of cruise tourism

TL;DR: In this paper , the authors investigated the perception of cruising during these outbreaks by analyzing the tweets on cruising using Natural Language Processing (NLP) and found a prevalent negative sentiment in most of the analyzed tweets, while the criticisms directed at the cruise industry were based on perceptions and stereotypes of the industry before the pandemic.
