Title: Label-Free Cross-Task LoRA Merging with Null-Space Compression
Abstract:
arXiv:2603.26317v1 Announce Type: cross Abstract: Model merging combines independently fine-tuned checkpoints without joint multi-task training. In the era of foundation-model, fine-tuning with Low-Rank Adaptation (LoRA) is prevalent, making LoRA merging a promising target. Existing approaches can work in homogeneous settings where all target tasks are classification but often fail when tasks span classification and regression. Approaches using entropy-based surrogates do not apply to regression
