Underfitting happens when a model is not good enough to understand all the details in the data. It’s like the model is too simple and misses important stuff.. This leads to poor performance on both the training and test sets. Model Overfitting. For a supervised machine learning task we want our model to do well on the test data whether it’s a classification task or a regression task. This phenomenon of doing well on test data is known as generalize on test data in machine learning terms. So the better a model generalizes on test data, the better the model is.

Overfitting occurs when a machine learning model matches the training data too closely, losing its ability to classify and predict new data. An overfit model finds many patterns, even if they are disconnected or irrelevant. The model continues to look for those patterns when new data is applied, however unrelated to the dataset.
