VisualDeltas: Learning Preferences from Visual Quality Perturbations
VisualDeltas is a lightweight preference-learning framework that extracts supervision from visual quality variations in multimodal data. It leverages image quality's systematic impact on perception and reasoning to induce informative preference signals without human annotations or external teachers. Supporting both label-free and label-based regimes, VisualDeltas consistently outperforms rejection-sampling fine-tuning, improves generalization, and extends to various visual degradations across diverse multimodal benchmarks and model scales.

VisualDeltas: Dynamic Preference Pair Generation
VisualDeltas constructs preference pairs by generating model responses for the same multimodal QA task under both High-Quality (HQ) and Low-Quality (LQ) visual inputs. This intrinsic sensitivity leads to divergent model behaviors, forming natural preference pairs for training.

Superior Robustness to Degraded Inputs
VisualDeltas significantly improves model performance on low-quality (LQ) inputs, demonstrating superior robustness compared to SFT, which often collapses under degradation. This indicates that preference learning from quality variations fosters more resilient models.
Case Study: Improved Reasoning Efficiency & Conciseness
Challenge: Degraded visual inputs often trigger compensatory but ineffective reasoning in VLMs, leading to verbose and less accurate responses. This 'working harder, achieving less' phenomenon wastes computational resources and diminishes output quality.
Solution: VisualDeltas' DPO training specifically leverages these behavioral differences. By contrasting long, incorrect LQ responses with concise, correct HQ responses, the model learns to suppress verbose patterns associated with degraded perception.
Outcome: After DPO training, models exhibit significantly more concise and accurate reasoning when presented with high-quality inputs. The token distribution shifts towards shorter, sharper responses, demonstrating improved reasoning efficiency and better grounding in visual perception.
Improved Reasoning Efficiency & Conciseness
VisualDeltas training not only improves accuracy but also encourages more concise and efficient reasoning. Degraded inputs often trigger compensatory, verbose, and ineffective responses, which DPO training learns to suppress, leading to shorter, more accurate outputs when given high-quality inputs.
