In this study, 4 algorithms, K-Means, Single-Linkage, DBSCAN and Self-Organizing Maps have been implemented and compared. F1 measure was used in order to evaluate precision and quality of clustering that by evaluating the obtained results, the SOM algorithm obtained high accuracy. However, the ...
Methods designed for unsupervised analysis use specialized clustering algorithms to detect and define cell populations for further downstream analysis. Here, we have performed an up-to-date, extensible performance comparison of clustering methods for high-dimensional flow and mass cytometry data. We ...

Graph clustering or community detection algorithms can summarize a graph in terms of coherent and tightly connected clusters. In this paper, we compare and contrast different techniques: METIS, Louvain, spectral clustering, SlashBurn and KCBC, our proposed k-core-based clustering method. Unlike prior...

We have looked at composition spreads of a number of other materials systems (about 10, all metallic alloys or oxides) using some of the same metrics and the clustering algorithms. Some systems were indeed more complicated than others: while most of the samples were textured, some were polycrys...
Here, we describe the extension of five leading algorithms for phase inference for handling father-mother-child trios. We performed a comprehensive assessment of the methods applied to both trios and to unrelated individuals, with a focus on genomic-scale problems, using both simulated data and ...
