null | Explain what overfitting is, in the context of machine learning. | Overfitting is a phenomenon in which a machine learning model performs better on training data than on new data. This occurs when a model is excessively complex and able to learn the underlying noise of the training data. As a result, the model doesn’t generalize well on previously unseen data and does not perform as e... | |
