The work argues that smaller models trained via supervised fine-tuning or offline reinforcement learning tend to memorize static trajectories rather than generalize.", "body_md": "While frontier vision-language models demonstrate strong capabilities in user interface (UI) navigation, their high inference costs prohibit everyday use. Conversely, smaller models trained via supervised fine-tuning (SFT) or offline reinforcement learning often memorize static trajectories, leading", "url": "https://wpnews.pro/news/online-dense-reinforcement-learning-with-planning-grounding-agent-for-ui-on-live", "canonical_source": "https://aiflash.com/news/142268/", "published_at": "2026-10-30 06:30:11+00:00", "updated_at": "2026-10-30 06:50:40.071313+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-agents", "ai-research", "machine-learning"], "entities": [], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/online-dense-reinforcement-learning-with-planning-grounding-agent-for-ui-on-live", "markdown": "https://wpnews.pro/news/online-dense-reinforcement-learning-with-planning-grounding-agent-for-ui-on-live.md", "text": "https://wpnews.pro/news/online-dense-reinforcement-learning-with-planning-grounding-agent-for-ui-on-live.txt", "jsonld": "https://wpnews.pro/news/online-dense-reinforcement-learning-with-planning-grounding-agent-for-ui-on-live.jsonld"}}
