Researchers have introduced TaDA, a novel algorithm for merging task-specific and domain-specific LoRA adapters in transformer models. Unlike previous methods that applied uniform weights, TaDA leverages the observed depth-dependent asymmetry between task and domain signals. The algorithm uses calibrated probe-guided gating for per-layer weighting and subspace-aware merging to combine adapter components effectively. This training-free approach results in a standard LoRA adapter with no inference overhead and demonstrates superior performance on scientific QA and image classification benchmarks. AI
