The passage around this formula
with the forward pass computing h = x + W x against the frozen base weight . The method’s authors report reducing the number of trainable parameters by roughly ten thousand times and GPU memory requirements by roughly three times relative to full fine-tuning of a 175-billion-parameter model, while matching or exceeding…
