FinZero targets risk-aware financial forecasting by uniting chart-based multimodal LLMs with uncertainty-quantified, interpretable reasoning. Its UARPO fine-tuning blends in-group and cross-group relative advantages with uncertainty adjustment, yielding high-confidence gains over GPT-4o. A new FVLDB image-text dataset supports evaluation. Despite leveraging known GRPO/PPO ideas, integration and empirical improvements are practically compelling.
