Discriminative Visual Process Rewards for Scaling Thinking at Test-Time with Images

ICML 2026poster

The “thinking with images” paradigm has led multimodal large language models to generate intermediate visual steps—such as cropping, annotation, spatial localization, and sketches—to enhance high-resolution perception and complex reasoning. However, existing multimodal Process Reward Models (PRMs) e…

Facial Dynamics in Video: Instruction Tuning for Improved Facial Expression Perception and Contextual Awareness

AAAI 2026technical

Facial expression captioning has found widespread application across various domains. Recently, the emergence of video Multimodal Large Language Models (MLLMs) has shown promise in general video understanding tasks. However, describing facial expressions within videos poses two major challenges for

GeoAgent: Learning to Geolocate Everywhere with Reinforced Geographic Characteristics

CVPR 2026

This paper presents GeoAgent, a model capable of reasoning closely with humans and deriving fine-grained address conclusions. Previous RL-based methods have achieved breakthroughs in performance and interpretability but still remain concerns because of their reliance on AI-generated chain-of-thought

See What I Mean: Aligning Vision and Language Representations for Video Fine-grained Object Understanding

CVPR 2026

We present SWIM (See What I Mean), a novel training strategy that aligns vision and language representations to enable fine-grained object understanding solely from textual prompts. Unlike existing approaches that require explicit visual prompts, such as masks or points, SWIM leverages mask supervis

CorrMatch: Label Propagation via Correlation Matching for Semi-Supervised Semantic Segmentation

CVPR 2024poster

This paper presents a simple but performant semi-supervised semantic segmentation approach called CorrMatch. Previous approaches mostly employ complicated training strategies to leverage unlabeled data but overlook the role of correlation maps in modeling the relationships between pairs of locations…
