What is a niche and niche count in clusters and how to calculate / determine niches ? Which basic paper / chapter/ material I must read?

28 April 2020 0 1K Report

I have been reading literature on clustering and could manage to get Fitness Proportionate Sharing etc mostly related to Evolutionary Algorithms. Basically I want to understand absolute basic concept of niches with an objective to separate a data set into distinct number of clusters with / without having the number of clusters in advance (a sort of unsupervised approach). If there is MATLAB command/code available, pl. let me know how to use.
