Simulating burn severity maps at 30 meters in two forested regions in California

open access: yesEnvironmental Research Letters, 2022
Climate change is altering wildfire and vegetation regimes in California’s forested ecosystems. Present day fires are seeing an increase in high burn severity area and high severity patch size.

Clustering [PDF]

open access: yes, 2008
Clustering techniques are used to arrange genes in some natural way, that is, to organize genes into groups or clusters with similar behavior across relevant tissue samples (or cell lines). These techniques can also be applied to tissues rather than genes.

Comparison of the digital economy development parameters in the EU countries in the context of bridging the digital divide [PDF]

open access: yesProblems and Perspectives in Management, 2020
The widespread use of information and communication technologies and subsequent transformations have led to the formation of a digital economy (DE). The European Union, as an international organization, has become the subject of building such an economy,

SACOC: A spectral-based ACO clustering algorithm [PDF]

open access: yes, 2014
The application of ACO-based algorithms in data mining is growing over the last few years and several supervised and unsupervised learning algorithms have been developed using this bio-inspired approach. Most recent works concerning unsupervised learning

UAV-Based Crowd Surveillance in Post COVID-19 Era

open access: yesIEEE Access, 2021
Since outdoor events are gradually allowed within the current pandemic situation, a close monitoring of the crowd activity is needed to avoid undesired contact and disease transmission. In this context, unmanned aerial vehicles (UAVs) can be occasionally

Word Sense Clustering and Clusterability [PDF]

open access: yesComputational Linguistics, 2016
Word sense disambiguation and the related field of automated word sense induction traditionally assume that the occurrences of a lemma can be partitioned into senses. But this seems to be a much easier task for some lemmas than others. Our work builds on recent work that proposes describing word meaning in a graded fashion rather than through a strict

Techniques for clustering gene expression data [PDF]

open access: yes, 2008
Many clustering techniques have been proposed for the analysis of gene expression data obtained from microarray experiments. However, choice of suitable method(s) for a given experimental dataset is not straightforward. Common approaches do not translate

Directional clustering through matrix factorization [PDF]

open access: yes, 2016
This paper deals with a clustering problem where feature vectors are clustered depending on the angle between feature vectors, that is, feature vectors are grouped together if they point roughly in the same direction.
