Why are a neural network's weights and biases changed during training?

Answer and explanation

Correct answer: To reduce loss and make predictions more accurate

During training, the network's prediction is compared with the correct target to calculate loss. Weights and biases are updated using this loss so that error decreases and the model makes better predictions. Option C is incorrect because the number of input features is normally determined by the data or network structure, not by updating weights and biases.
