Ensemble Learning Visualizer

This interactive tool helps visualize how different ensemble learning methods work. Select a method below to explore step-by-step:

  • Bagging: Trains multiple models on random subsets of data and combines them through equal voting/averaging
  • Boosting: Trains models sequentially, with each model focusing on errors made by previous models
  • Stacking: Trains multiple base models and a meta-model that learns how to best combine their predictions

Bagging (Bootstrap Aggregating)

Bagging creates multiple training subsets by random sampling with replacement, trains a model on each subset, and combines their predictions.

Boosting

Boosting trains models sequentially, with each model giving more attention to instances that previous models struggled with.
