GUI-G²: Gaussian Reward Modeling for GUI Grounding

AAAI 2026technical

Graphical User Interface (GUI) grounding maps natural language instructions to precise interface locations for autonomous interaction. Current reinforcement learning approaches use binary rewards that treat elements as hit-or-miss targets, creating sparse signals that ignore the continuous nature of

GUI-SAGE: Enhancing GUI Automation with Self-Explanatory Learning

CVPR 2026

Reinforcement learning with verifiable rewards (RLVR) has shown promise for GUI automation, enabling agents to learn from binary task completion signals. However, when task difficulty exceeds model capacity, on-policy exploration fails to discover correct actions, creating zero-advantage traps that

Test-Time Reinforcement Learning for GUI Grounding via Region Consistency

AAAI 2026technical

Graphical User Interface (GUI) grounding, the task of mapping natural language instructions to precise screen coordinates, is fundamental to autonomous GUI agents. While existing methods achieve strong performance through extensive supervised training or reinforcement learning with labeled rewards,

UI-R1: Enhancing Efficient Action Prediction of GUI Agents by Reinforcement Learning

AAAI 2026technical

The recent DeepSeek-R1 has showcased the emergence of reasoning capabilities in large language models (LLMs) through reinforcement learning (RL) with rule-based rewards. Despite its success in language tasks, its application in multimodal domains, particularly in graphic user interface (GUI) agent t

ProtPainter: Draw or Drag Protein via Topology-guided Diffusion

ICLR 2025poster

Recent advances in protein backbone generation have achieved promising results under structural, functional, or physical constraints. However, existing methods lack the flexibility for precise topology control, limiting navigation of the backbone space. We present $\textbf{ProtPainter}$, a diffusion…
