In the context of a machine learning model, what is overfitting?
When a model fails to learn from the data.
When a model learns the training data too well and doesn't generalize.
When a model is too simple to make accurate predictions.
When a model uses the correct amount of data.
Vysvětlení
Overfitting happens when the model fits the training data very closely, including noise, which leads to poor performance on new data.
