The overfitting phenomenon occurs when the statistical machine learning model learns the training data set so well that it performs poorly on unseen data sets. In other words, this means that the predicted values match the true observed values in the training data set too well, causing what is known as overfitting.Building machine learning models is a constant battle to find the sweet spot between underfitting and overfitting. The best models will do a good job of generalizing the underlying relationships in the data without modeling the noise in the data. Recognizing Underfitting and OverfittingIn our previous post, we went over two of the most common problems machine learning engineers face when developing a model: underfitting and overfitting.

Overfitting in Machine Learning. When a model learns the training data too well, it leads to overfitting. The details and noise in the training data are learned to the extent that it negatively impacts the performance of the model on new data. The minor fluctuations and noise are learned as concepts by the model.In machine learning, models that are too “flexible” are more prone to overfitting. “Flexible” models include models that have a large number of learnable parameters, like deep neural networks, or models that can otherwise adapt themselves in very fine-grained ways to the training data, such as gradient boosted trees.Abstract.
