FiLoRA: Focus-and-Ignore LoRA for Controllable Feature Reliance

FiLoRA is an instruction‑conditioned, parameter‑efficient adaptation framework that allows controllable modulation of feature reliance in multimodal foundation models. It decomposes adaptation into feature‑aligned low‑rank modules and uses instruction‑conditioned gating so that natural language instructions can act as computation‑level control signals over internal representations. Experiments on classification and generative multimodal tasks show that FiLoRA consistently and interpretable shifts feature reliance, amplifying or suppressing feature groups per instruction without changing task semantics.

Dynamic Cross-Modal Prompt Generation for Multimodal Continual Instruction Tuning

Dynamic Cross-Modal Prompt Generation (DRAPE) is a prompt-learning framework designed for Multimodal Continual Instruction Tuning (MCIT). It generates continuous, instance-specific soft prompts by cross-attending textual instructions with visual patch features, rather than selecting from a fixed prompt pool. DRAPE also incorporates null‑space gradient projection to reduce forgetting and uses CLIP‑based prototype routing for task‑label‑free inference, achieving state‑of‑the‑art results on MCIT benchmarks.
