Hi Prachi,
The best clustering method depends on the specific characteristics of your data and your analysis goals. Here's a brief overview to help you decide:
K-Means Clustering:
  • Best For: Well-separated, spherical clusters.
  • Advantages: Simple and fast; works well when clusters are distinct.
  • Limitations: Assumes clusters of similar size and shape; sensitive to outliers.
Fuzzy C-Means Clustering:
  • Best For: Data where cluster boundaries are not well-defined.
  • Advantages: Allows data points to belong to multiple clusters with varying degrees of membership, providing more flexibility.
  • Limitations: Slower than K-means; might be more complex to interpret due to membership degrees.
Spatial Fuzzy C-Means Clustering:
  • Best For: Spatial data where neighboring data points influence cluster membership.
  • Advantages: Incorporates spatial information, which can improve clustering results for spatially correlated data.
  • Limitations: More computationally intensive; requires careful tuning of spatial parameters.
In summary, if your data has clear, well-separated clusters, K-means might be the simplest and most efficient choice. If your data has overlapping clusters and you want more flexibility, fuzzy C-means could be better. For spatial data with geographical or spatial dependencies, spatial fuzzy C-means might provide more accurate results. Consider the nature of your data and the specific requirements of your analysis when choosing the method.

You can try them all out in the Classification Learner app on the Apps tab of the tool ribbon. You can try them with your actual data and compare the accuracies, if you have ground truth data that you know the correct classification for.
