Overfitting is a fundamental issue in supervised machine learning which prevents us from perfectly generalizing the models to well fit observed data on training data, as well as unseen data on testing set. Because of the presence of noise, the limited size of training set, and the complexity of classifiers, overfitting happens. simply shopWebb28 aug. 2024 · Smaller batch sizes make it easier to fit one batch worth of training data in memory (i.e. when using a GPU). A third reason is that the batch size is often set at something small, such as 32 examples, and is not tuned by the practitioner.
