Snapshot Spectral Clustering -- a costless approach to deep clustering ensembles generation

Despite tremendous advancements in Artificial Intelligence, learning from large sets of data in an unsupervised manner remains a significant challenge. Classical clustering algorithms often fail to discover complex dependencies in large datasets, esp

Incremental Recursive Ranking Grouping for Large Scale Global Optimization

Autor: Komarnicki, Marcin Michal, Przewozniczek, Michal Witold, Kwasnicka, Halina, Walkowiak, Krzysztof

Real-world optimization problems may have a different underlying structure. In black-box optimization, the dependencies between decision variables remain unknown. However, some techniques can discover such interactions accurately. In Large Scale Glob

Hierarchical Data Generator based on Tree-Structured Stick Breaking Process for Benchmarking Clustering Methods

Autor: Olech, Łukasz P., Spytkowski, Michał, Kwaśnicka, Halina, Michalewicz, Zbigniew

Object Cluster Hierarchies is a new variant of Hierarchical Cluster Analysis that gains interest in the field of Machine Learning. Being still at an early stage of development, the lack of tools for systematic analysis of Object Cluster Hierarchies i

Hierarchy of Groups Evaluation Using Different F-score Variants

Autor: Spytkowski, Michał, Olech, Łukasz P., Kwaśnicka, Halina

Publikováno v: ACIIDS 2016, Da Nang, Vietnam, March 14-16, 2016, pp. 654 (Springer Berlin Heidelberg)

The paper presents a cursory examination of clustering, focusing on a rarely explored field of hierarchy of clusters. Based on this, a short discussion of clustering quality measures is presented and the F-score measure is examined more deeply. As th
