Application of Causal Inference Techniques to the Maximum Weight Independent Set Problem

2023 · arXiv (Cornell University)

A powerful technique for solving combinatorial optimization problems is to reduce the search space without compromising the solution quality by exploring intrinsic mathematical properties of the problems. For the maximum weight independent set (MWIS) problem, …

MTL-LoRA: Low-Rank Adaptation for Multi-Task Learning

2024 · arXiv (Cornell University)

Parameter-efficient fine-tuning (PEFT) has been widely employed for domain adaptation, with LoRA being one of the most prominent methods due to its simplicity and effectiveness. However, in multi-task learning (MTL) scenarios, LoRA tends to obscure …
