Approximate kNN Classification for Biomedical Data

no code implementations3 Dec 2020 Panagiotis Anagnostou, Petros T. Barmbas, Aristidis G. Vrahatis, Sotiris K. Tasoulis

Regarding the classification process for scRNA-seq data, an appropriate method is the k Nearest Neighbor (kNN) classifier since it is usually utilized for large-scale prediction tasks due to its simplicity, minimal parameterization, and model-free nature.

Minimum Density Hyperplanes

no code implementations15 Jul 2015 Nicos G. Pavlidis, David P. Hofmeyr, Sotiris K. Tasoulis

Associating distinct groups of objects (clusters) with contiguous regions of high probability density (high-density clusters), is central to many statistical and machine learning approaches to the classification of unlabelled data.
