Overfitting is a common problem in data mining when complex models are trained on a small dataset leading to accurate predictions on the training set but poor generalization on new data. It occurs when the model fits the noise in the data instead of the underlying trend. This results in an over-optimistic estimate of model performance, and the model becomes less accurate when applied to new data.
