Layered neural network diagram showing low-rank adapter matrices branching off frozen weights.

Building a LoRA Training Loop From Scratch in Pure NumPy

Build a working LoRA fine-tuning loop in pure NumPy, computing every gradient by hand through low-rank adapters. A practical side project that demonstrates real systems understanding to hiring managers.
