Questions & Step-by-Step Solutions

What is the main advantage of using Gaussian Mixture Models (GMM) over K-Means?
  • Step 1: Understand that K-Means is a clustering method that groups data into clusters based on their distance from the center of each cluster.
  • Step 2: Recognize that K-Means assumes all clusters are spherical and of similar size, which can limit its effectiveness.
  • Step 3: Learn that Gaussian Mixture Models (GMM) can represent clusters that are not just spherical but can have different shapes and sizes.
  • Step 4: Realize that GMM uses a probabilistic approach, allowing it to better fit the data and capture the underlying distribution of the clusters.
