  "text": "Planning with the views:\n\nCan VLMs predict how each camera move changes the view, and plan many such moves ahead?\n\nWe introduce ViewSuite with 6 DoF camera control and ~165K task instances, testing:\nPath-to-View\nView-to-Path\nInteractive View Planning\n\nA sharp Planning Gap emerges:\n+ can roughly \"track\" how camera action changes views\n- cannot \"compose\" a plan towards a target view at all\n\nWe then try to teach VLMs with Reinforcement Learning.  - RL cannot teach VLMs such planning ability, only 2.5% success rate with Qwen2.5-VL-7B.\n+ With View Graph Distillation (our RL-Graph-SFT framework), 2.5% → 47.8%\n\nBelow, we answer these questions: \nQ1. What are the failure modes?\nQ2. How can we make RL work? \nQ3. What has the model learned? Can we open up the model to see before/after? Can such spatial priors transfer to other view related tasks?\n\nLed by @James_KKW, great to work with @LINJIEFUN @zhengyuan_yang @shiqi_chen17 @wzenus @drfeifei @jiajunwu_cs Leonidas Guibas, Lijuan Wang.\n\nA joint efforts with @StanfordAILab @StanfordSVL @MSFTResearch.",
