Foundational
Bias-Variance TradeoffBias is error from a model too simple to capture the pattern; variance is error from a model so flexible it memorizes noise. Total generalization error is roughly their sum, and the whole craft of model fitting is pushing both down at once instead of trading one for the other.📊 Evaluation & ML Foundations

Overfitting and RegularizationOverfitting is when a model learns the noise in your training data instead of the signal, so it scores beautifully on data it has seen and falls apart on data it has not. You spot it from the gap between train and validation error, and you fight it with more data, regularization, early stopping, dropout, and honest cross-validation.📊 Evaluation & ML Foundations
