Questions & Step-by-Step Solutions

In the context of neural networks, what does 'dropout' refer to?
  • Step 1: Understand that neural networks are models that learn from data.
  • Step 2: Know that during training, these models can sometimes learn too much from the training data, which is called overfitting.
  • Step 3: Dropout is a technique used to help prevent overfitting.
  • Step 4: During training, dropout randomly turns off (sets to zero) a certain percentage of neurons in the network.
  • Step 5: By doing this, the model learns to rely on different neurons and not just a few, making it more robust.
  • Step 6: When the model is tested or used after training, all neurons are active, which helps it perform better on new data.
