  4. To determine the number of layers

Questions & Step-by-Step Solutions

What is the purpose of the loss function in a neural network?
  • Step 1: Understand that a neural network makes predictions based on input data.
  • Step 2: Know that these predictions are compared to actual target values (the correct answers).
  • Step 3: The loss function measures the difference between the predictions and the actual target values.
  • Step 4: A smaller loss value means the predictions are closer to the actual values, indicating better performance.
  • Step 5: The goal of training the neural network is to minimize this loss value, improving its accuracy.
