DisTaC: Conditioning Task Vectors via Distillation for Robust Model Merging

ICLR 2026poster

Model merging has emerged as an efficient and flexible paradigm for multi-task learning, with numerous methods being proposed in recent years. However, these state-of-the-art techniques are typically evaluated on benchmark suites that are highly favorable to model merging, and their robustness in m…

On Fairness of Task Arithmetic: The Role of Task Vectors

ICLR 2026poster

Model editing techniques, particularly task arithmetic with task vectors, offer an efficient alternative to full fine-tuning by enabling direct parameter updates through simple arithmetic operations. While this approach promises substantial computational savings, its impact on fairness has remained…

Mastering Task Arithmetic: $\tau$Jp as a Key Indicator for Weight Disentanglement

ICLR 2025poster

Model-editing techniques using task arithmetic have rapidly gained attention. Through task arithmetic, simply through arithmetic operations on the weights of pre-trained and fine-tuned models create desired models, such as multi-task models, models in which specific tasks are unsolvable, or domain-t…
