The author presents their ICML workshop accepted work, **SRM-LoRA**, which aims to mathematically mitigate LLM hallucinations. ### Key Methods - It reshapes the gradient direction during backpropagation using a LoRA update method inspired by **sub-Riemannian metric**. - The metric is based on parameter sensitivity to loss, similar to a `gradient(loss) / gradient(parameter)` signal. - This suppresses "expensive" update directions while **not altering forward computation or inference overhead**. ### Results and Arguments - Training solely on **HaluEval-QA** improves factuality on both in-distribution and out-of-distribution benchmarks. - The author argues that the key to math being more effective in AI isn't simply introducing more complex learnable metrics, but appropriately designing elements from different theories for specific problems.
