What is LoRA (Low-Rank Adaptation)?

Correct! Well done.

Incorrect.

The correct answer is B) A parameter-efficient fine-tuning method adding low-rank matrices to transformer layers, adapting LLMs with far fewer trainable parameters

B

Correct Answer

A parameter-efficient fine-tuning method adding low-rank matrices to transformer layers, adapting LLMs with far fewer trainable parameters

Explanation

LoRA (Hu et al., 2021): instead of fine-tuning all weights W, add ΔW = BA where B (d×r), A (r×d), r<<d. Train only A,B (0.1% of parameters). Enables LLM fine-tuning on consumer GPUs.
