Solution

The backpropagation algorithm is used for option c: To find the optimal weights and biases of a neural network.

Here's a step-by-step explanation:

  1. Initialize the neural network with random weights and biases.

  2. Feed the network with input data and calculate the output. This is known as forward propagation.

  3. Compare the network's output with the expected output. The difference is the error.

  4. Use the backpropagation algorithm to calculate the gradient of the error with respect to each weight and bias in the network. This involves applying the chain rule to compute the derivative of the error with respect to the weights and biases. This is done in reverse order, from the output layer back to the input layer, hence the name "backpropagation".

  5. Update the weights and biases in the direction that reduces the
