What is dropout in neural network training?
Answer
Dropout is a regularization technique used during neural network training to prevent overfitting.
During each training step, a fraction of the neurons (and their corresponding connections) are randomly “dropped out” (i.e., set their activations to zero). This forces the network to learn more robust features because it can’t rely on any single neuron; instead, it learns distributed representations by effectively training an ensemble of smaller sub-networks. This will improve the model’s ability to generalize to unseen data.
