Overfitting and underfitting are two common problems in machine learning that occur when the model is either too complex or too simple to accurately represent the underlying data. Overfitting happens when the model is too complex and learns the noise in the data, leading to poor performance on new, unseen data. In machine learning, you must have come across the term Overfitting. Overfitting is a phenomenon where a machine learning model models the training data too well but fails to perform well on the testing data. Performing sufficiently good on testing data is considered as a kind of ultimatum in machine learning. Overfitting is a common phenomenon you should look out for any time you are training a machine learning model.

The degree represents how much flexibility is in the model, with a higher power allowing the model freedom to hit as many data points as possible. An underfit model will be less flexible and cannot account for the data. Jan 31, 2022 · Overfitting happens when: The training data is not cleaned and contains some “garbage” values. The model captures the noise in the training data and fails to generalize the model's learning. The model has a high variance. The training data size is insufficient, and the model trains on the limited training data for several epochs. On overfitting and the effective number of hidden units.
