A Gaussian mixture model (GMM) is a category of probabilistic model which states that all generated data points are derived from a mixture of a finite Gaussian distributions that has no known parameters. The parameters for Gaussian mixture models are derived either from maximum a posteriori estimati...
Clustering in data mining is used to group a set of objects into clusters based on the similarity between them. With this blog learn about its methods and applications.
Clustering Using a Gaussian Mixture Model Unsupervised Machine Learning | Introduction to Machine Learning, Part 2(4:15) Why Clustering Is Important Clustering is a significant area ofartificial intelligence. It plays an important role in various domains by offering valuable insights into data and unco...
Clustering is an unsupervised machine learning algorithm that organizes and classifies different objects, data points, or observations into groups or clusters based on similarities or patterns.
I tried a gaussian mixture model, specifically the scikit-learn one, but I modified the class to include a term in the log likelihood that is proportional to the entropy of the distances of the gaussians means (to encourage equally distributed distances). ...

Mean Shift Algorithm − It is a clustering technique that identifies clusters by finding high data density areas. It is an iterative process, where mean of each data point is shifted towards the densest area of the data. Gaussian Mixture Models − It is a probabilistic model that is a co...
A probabilistic model is an unsupervised technique that helps us solve density estimation or “soft” clustering problems. In probabilistic clustering, data points are clustered based on the likelihood that they belong to a particular distribution. The Gaussian Mixture Model (GMM) is the one of the...
