V-Thinker++: Human-Guided Interactive Reasoning Loops for Transparency and Trust

TL;DR: Let’s teach V-Thinker to ask humans for help on tough or uncertain image questions, learning from human interaction to improve both accuracy and transparency. The core experiment tests whether human-in-the-loop feedback—especially on ambiguous cases—enhances model performance and user trust compared to fully automated workflows.

Research Question: Can incorporating explicit human-guided intervention into the interactive reasoning process of image-centric LMMs improve answer reliability, model transparency, and user trust, especially in edge cases or ambiguous scenarios?

Hypothesis: Integrating a fallback mechanism for “human consultation” will not only boost accuracy on challenging instances—where current V-Thinker models may struggle—but also yield more explainable and confidence-calibrated outputs.

Experiment Plan: - Identify and log V-Thinker’s high-uncertainty or low-confidence outputs on VTBench and other interactive reasoning datasets.

• Design an interface where, on these cases, the model pauses and queries a human for region selection, annotation, or reasoning steps.
• Retrain the model using these interactions, creating a dataset of model-human “interactive loops.”
• Evaluate reasoning accuracy, confidence calibration, and user satisfaction, comparing this hybrid approach to the standard fully-automated pipeline.
• Study qualitative shifts in explanations and decisions, analyzing whether transparency is improved.
