MASPOB: Bandit-Based Prompt Optimization for Multi-Agent Systems with Graph Neural Networks

ICML 2026spotlight

Large Language Models (LLMs) have achieved significant success across a wide range of tasks, serving as the cognitive backbone for Multi-Agent Systems (MAS) designed to orchestrate complex practical workflows. Given that MAS performance is highly sensitive to input prompts and many deployment scenar…

PMNI: Pose-free Multi-view Normal Integration for Reflective and Textureless Surface Reconstruction

CVPR 2025poster

Reflective and textureless surfaces remain a challenge in multi-view 3D reconstruction. Both camera pose calibration and shape reconstruction often fail due to insufficient or unreliable cross-view visual features. To address these issues, we present PMNI (Pose-free Multi-view Normal Integration), a…

Self-Supervised Selective-Guided Diffusion Model for Old-Photo Face Restoration

NeurIPS 2025poster

Old-photo face restoration poses significant challenges due to compounded degradations such as breakage, fading, and severe blur. Existing pre-trained diffusion-guided methods either rely on explicit degradation priors or global statistical guidance, which struggle with localized artifacts or face c…
