density-based clusteringunsupervised learningdistance metricIn this paper, we propose a fully autonomous density-based clustering algorithm named 'Ocean', which is inspired by the oceanic landscape and phenomena
each cluster on spatial maps of the brain (Supplementary Fig.8a) using neuroimaging tools44,45, it became apparent that the amygdala and hippocampus tended to have relatively high pathology scores across all clusters. Collectively, these findings suggest that the solution of our clustering algorithm ...
functional (semantic) relations or a combination of both1,2. Learned category representations help animals and humans to react to novel experiences because they facilitate extrapolation from knowledge already acquired3,4. Learning and recalling of categories activates a large number of brain areas, incl...

(See for more discussion about the differences between the two visualization techniques Leydesdorff and Rafols (2012).) However, the clustering algorithm in VOSviewer distinguished four, in our opinion highly meaningful, groups (Waltman et al. 2010). The organization into these four groups (...
To develop a typologically-diverse set of languages, Stoll and Bickel (2013) applied a fuzzy clustering algorithm used by Rousseeuw and Leonard (1990) that takes as input thousands of languages and their typological feature values (e.g. grammatical case, inflection categories, degree of synthesis...
In this study we use RandomForest (RF), a machine learning algorithm to model species distribution, density/abundance based (SDM/SAM) and predict the biodiversity distribution (richness and density, ind.m−2) of three basic earthworms ecological categories: epigeic, endogeic and anecic (including...
In this sense, our work provides a large-scale generalization of recent advances27,54,73 that defined brain states in terms of β maps from a task-based fMRI contrast, task-derived k-means clustering or electrocorticography signal power associated with memory task performance31. Importantly, we...
Most current research on identifying crisis information from social media rely on the use of supervised and unsupervised Machine Learning (ML) methods, such as classifiers, clustering and language models [1]. More recently, deep learning has emerged as a new ML technique able to capture high leve...
