Deep leаrning methоd leаrns its weights thrоugh bаckprоpagation during the optimization. Backpropagation is the algorithm used to train neural networks by computing the gradient of a loss function with respect to the network’s parameters (weights and biases). Stochastic gradient descent (SGD) and Adam methods are widely used for this process.  Please match the loss function with each task
