: It is most effective in large, complex networks where the risk of overfitting is high.

: By making the network "unreliable," you force it to learn redundant representations. No single neuron can become overly specialized or carry too much weight.

: A dropout rate of 0.5 is a common industry standard for hidden layers. It means that in every training step, there is a 50% chance any given neuron will be deactivated.

: For the best results, combine dropout with techniques like Max-Norm Regularization and decaying learning rates.
