Enhancing Spatial Reasoning Through Visual and Textual Thinking

AAAI 2026technical

The spatial reasoning task aims to reason about the spatial relationships in 2D and 3D space, which is a fundamental capability for Visual Question Answering (VQA) and robotics. Although vision language models (VLMs) have developed rapidly in recent years, they are still struggling with the spatial

FGD-Align: Pluralistic Alignment for Large Language Models via Fuzzy Group Decision-Making

AAAI 2026technical

Ensuring alignment with human values is essential for modern large language models (LLMs), especially amid growing concerns around AI safety and social impact. Yet achieving such alignment remains challenging due to the limited, noisy, and often conflicting nature of human feedback from diverse anno

GraphDAE-PU: Graph Denosing Auto-Encoder for Arbitrary-Scale Point Cloud Upsampling

ICASSP 2025accepted

Existing learning-based arbitrary-scale point cloud upsampling methods are usually challenged with limited point cloud feature representation and noise-sensitive refinement of coarse point cloud. In this paper, we introduce GraphDAE-PU, a novel framework for point cloud upsampling that addresses the…
