Cross-entropy measures the difference between a predicted probability distribution and the correct target distribution.
Backpropagation trains neural networks by tracing prediction errors backward through their layers and adjusting internal weights to improve future results.
Gradient descent is an optimization algorithm that reduces model error by repeatedly adjusting parameters in the direction indicated by the loss gradient.
