What is Overfitting? IBM

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.

Transcribed image text: Using the training data, we see the decision tree works very well. However, if it is overfit then performance should decline using test data. The lower accuracy of the test data indicates our model is overfit. To get a more realistic estimate of our decision tree accuracy, we will use 5 -fold cross-validation. only one chris bandi
