Overfitting vs. Underfitting: A Complete Example

WebHowever, if you train the model too much or add too many features to it, you may overfit your model, resulting in low bias but high variance (i.e. the bias-variance tradeoff). In this scenario, the statistical model fits too closely against its training data, rendering it unable to generalize well to new data points.
