Researchers have developed a new method called Moonwalk that bypasses the need to store intermediate activations during the forward pass of neural network training. This technique, based on inverse-forward differentiation, allows for the training of significantly deeper networks within the same memory constraints as traditional backpropagation. Moonwalk achieves this by using a novel vector-inverse-Jacobian product operator and a mixed-mode algorithm that reconstructs parameter gradients in a forward sweep. AI
