Cluster Quality Analysis Using Silhouette Score
International Conference on Data Science and Advanced Analytics, 2020 Clustering is an important phase in data mining. Selecting the number of clusters in a clustering algorithm, e.g. choosing the best value of k in the various k-means algorithms [1], can be difficult.

Developmental feedbacks and the emergence of individuality
Royal Society Open Science, 2022 Behavioural individuality is a hallmark of animal life, with major consequences for fitness, ecology, and evolution. One of the most widely invoked explanations for this variation is that feedback loops between an animal's behaviour and its state (e.g ...

A Non-blocking Buddy System for Scalable Memory Allocation on Multi-core Machines [PDF]
, 2018 Common implementations of core memory allocation components handle concurrent allocation/release requests by synchronizing threads via spin-locks. This approach is not prone to scale with large thread counts, a problem that has been addressed in the ...

Word Sense Clustering and Clusterability [PDF]
Computational 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

Coral endosymbiont growth is enhanced by metabolic interactions with bacteria
Nature Communications, 2023 Bacteria are key contributors to microalgae resource acquisition, competitive performance, and functional diversity, but their potential metabolic interactions with coral microalgal endosymbionts (Symbiodiniaceae) have been largely overlooked.

Community Structure in Large Networks: Natural Cluster Sizes and the Absence of Large Well-Defined Clusters [PDF]
Internet Mathematics, 2008 A large body of work has been devoted to defining and identifying clusters or communities in social and information networks, i.e., in graphs in which the nodes represent underlying social entities and the edges represent some sort of interaction between
