What this part means
The expressions on both sides represent the same quantity under the stated assumptions.
Its job in the formula
The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

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 full fine-tuning quality and adding no additional inference latency, since the low-rank update can be merged back into the base weight at deployment time [ 1 ] . QLoRA extends the same idea to quantized base weights, and its authors report finetuning a 65-billion-parameter model on a single 48-gigabyte GPU while preserving full 16-bit finetuning performance,…
