Researchers have introduced Marvo, a novel self-evolving visual agent designed to learn tool invocation from unlabeled images. Marvo employs a challenger agent to generate questions from images and a solver agent that learns tool usage through reinforcement learning. By incorporating a margin reward, the system adaptively scales question complexity without human supervision, leading to significant accuracy improvements of up to 7.1% across various reasoning benchmarks. AI
IMPACT This approach could reduce the cost of training visual agents by eliminating the need for curated question-answer pairs.
