Dropout is a technique used in neural networks to improve model performance and reduce overfitting. It works by randomly "dropping out" (setting to zero) a certain percentage of input and hidden units during the training process. By doing so, it helps the model generalize better and reduces the reliance on specific units, making the model more robust and less likely to overfit the training data.
During each training iteration, dropout randomly selects a fraction of the input and hidden units to be "dropped out" or set to zero. The fraction of units to be dropped out is a hyperparameter that can be tuned. This process helps prevent the neural network from relying too heavily on specific units and encourages the network to learn more robust and general features. Dropout effectively creates an ensemble of multiple subnetworks that share parameters, leading to improved generalization and reducing the risk of overfitting.
Dropout is important because it helps address the overfitting problem in neural networks. Overfitting occurs when the model performs well on the training data but fails to generalize to unseen data. By randomly dropping out units, dropout forces the network to learn more redundant representations and prevents it from relying too heavily on specific units. This regularization technique improves the network's ability to generalize and perform well on unseen data.
