Researchers have developed LiST, a novel framework for test-time LoRA fusion that dynamically adapts LoRA adapters to specific inputs. This method creates a target-conditioned local simplex from a bank of LoRA adapters, enabling the search for sample-specific fusion weights during inference. LiST builds joint task representations and uses a prompt-level energy with various constraints to select candidate weights, falling back to a prior if acceptance rules are not met. Experiments demonstrate that LiST surpasses static merging and conventional test-time adaptation methods on multimodal and language benchmarks, maintaining adapter utility and enhancing robustness on new tasks.
