Model Robustness

Ensemble Variance Explorer

Why averaging many learners can produce more stable predictions.

What This Shows

Compare individual noisy learners with their aggregate behavior. The applet shows the central intuition behind ensemble models: independent errors can partially cancel out, reducing variance and improving reliability without requiring every base model to be perfect.

Technical Challenge

Improving prediction stability when individual models are sensitive to the data sample.

My Contribution

Created an interactive demonstration of variance reduction through aggregation.
