Beyond Confidence: Adaptive and Coherent Decoding for Diffusion Language Models

ICML 2026poster

Diffusion Language Models (DLMs) have recently achieved significant success due to their any-order generation capabilities. However, existing inference methods typically rely on local, immediate-step metrics—such as confidence or entropy—which inherently lack a more reliable perspective, leading to …

FlatLand: Personalized Graph Federated Learning via Tailored Lorentz Space

ICML 2026oral

Personalization has become a pivotal field of study in contemporary intelligent systems. While large language models (LLMs) excel at general knowledge tasks, they often struggle with personalization, i.e., adapting their outputs to individual user expectations. Existing approaches that steer LLM beh…

MMSearch-Plus: Benchmarking Provenance-Aware Search for Multimodal Browsing Agents

ICLR 2026poster

Existing multimodal browsing benchmarks often fail to require genuine multimodal reasoning, as many tasks can be solved with text-only heuristics without vision-in-the-loop verification. We introduce MMSearch-Plus, a 311-task benchmark that enforces multimodal understanding by requiring extraction a…

Actial: Activate Spatial Reasoning Ability of Multimodal Large Language Models

NeurIPS 2025poster

Recent advances in Multimodal Large Language Models (MLLMs) have significantly improved 2D visual understanding, prompting interest in their application to complex 3D reasoning tasks. However, it remains unclear whether these models can effectively capture the detailed spatial information required f…

A Systematic Survey on Federated Semi-supervised Learning

IJCAI 2024poster

Federated learning (FL) revolutionizes distributed machine learning by enabling devices to collaboratively learn a model while maintaining data privacy. However, FL usually faces a critical challenge with limited labeled data, making semi-supervised learning (SSL) crucial for utilizing abundant unla…
