Numerical Gradient Verification

this year medium (<1 hr) | debugging gradient calculus numerical-stability backpropagation

Understanding and correctly implementing backpropagation is crucial in deep learning. A common way to debug backpropagation is using numerical gradient checking. This involves approximating the...
Backpropagation for a Single-Layer Network

this year hard (>1 hr) | gradient deep-learning calculus backpropagation neural-networks

Backpropagation is the cornerstone algorithm for training neural networks. It efficiently calculates the gradients of the loss function with respect to all the weights and biases in the network by...
