How does Backpropagation work?

The technique was popularized for neural networks by Rumelhart, Hinton, and Williams in their 1986 paper, building on ideas going back to the 1960s. Backpropagation is the foundation of every deep learning training pipeline including LLM pretraining, SFT, RLHF, DPO, and LoRA adapter training. The platform strengthens en
