LoRA on the Go: Instance-level Dynamic LoRA Selection and Merging

Seungeon Lee, Soumi Das, Manish Gupta +1

Low-Rank Adaptation (LoRA) has emerged as a parameter-efficient approach for fine-tuning large language models. However, conventional LoRA adapters are typically trained for a sing…

Rethinking Memorization Measures and their Implications in Large Language Models

Bishwamittra Ghosh, Soumi Das, Qinyuan Wu +4

Concerned with privacy threats, memorization in LLMs is often seen as undesirable, specifically for learning. In this paper, we study whether memorization can be avoided when optim…
