"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. " - Overfitting the training data
