Explore unsupervised learning concepts visually

📌 K-Means Clustering

Click on the canvas to add data points, then run k-means to see how the algorithm clusters your data!

📈 Scree Plot (Elbow Method)

Shows total within-cluster sum of squares for different k values. Look for the "elbow" to find optimal k!

🌳 Hierarchical Clustering

Click to add points, then watch the dendrogram build as clusters merge!

Linkage Methods:

  • Complete: Uses largest distance between any two points in clusters
  • Single: Uses smallest distance between any two points in clusters
  • Average: Uses average distance between all pairs of points

✂️ Cut the Tree: After building the dendrogram, use the slider to cut at different heights and see different cluster groupings! Points will be color-coded by cluster.

📊 Principal Component Analysis (PCA)

Click on the canvas to add data points or generate correlated data, then see how PCA finds the principal components!

📈 Scree Plot

Shows the percentage of variance explained by each principal component
