Dropout

Dropout is a regularization technique used in neural networks to prevent overfitting. It works by randomly “dropping out” a subset of neurons during each training iteration, effectively ignoring them. This encourages the network to learn more robust features by not relying too heavily on any single neuron. Typically, a dropout rate is defined, indicating the percentage of neurons to be dropped. While dropout was once a popular choice for regularization, it has seen competition from techniques like batch normalization. Nonetheless, it remains a simple and effective method for enhancing the generalization of neural networks.
