Researchers have introduced Rita, a novel reinforcement learning framework designed to improve the consistency between a vision-language model's reasoning process and its final answer. Rita addresses the issue of "thinking drift," where models may arrive at a correct output despite flawed internal logic. The framework utilizes two new rewards, a thinking reward and a consistency reward, derived from conditional probabilities of reference answers, and incorporates a difficulty-aware data filtering strategy. Experiments on the EgoIntention and RefEgo-Int benchmarks demonstrate Rita's superior performance over existing supervised fine-tuning and standard RL methods. AI
IMPACT Enhances the reliability of vision-language models by ensuring their reasoning aligns with their outputs, potentially improving performance in complex tasks.
