WebDec 24, 2024 · A new fuzzy k-means clustering algorithm that helps to minimize the within-cluster dispersion and maximize the negative entropy to determine clusters to contribute to the association of data points is presented. This paper presents a new fuzzy k-means algorithm for the clustering of high dimensional data in various subspaces. Since, In the … WebJan 11, 2024 · Entropy is a measure of disorder or uncertainty and the goal of machine learning models and Data Scientists in general is to reduce uncertainty. Now we know how to measure disorder. Next we need a metric to measure the reduction of this disorder in our target variable/class given additional information ( features/independent variables) about it. WebThe entopy weighted k-means clustering algorithm is a subspace clusterer ideal for high dimen-sional data. Along with each cluster we also obtain variable weights that provide a relative measure of the importance of each variable to that cluster. The algorithm is based on the k-means approach to clustering. An initial set of k means are identified books 4u.com
