Query-Aware Flow Diffusion for Graph-Based RAG with Retrieval Guarantees

ICLR 2026poster

Graph-based Retrieval-Augmented Generation (RAG) systems leverage interconnected knowledge structures to capture complex relationships that flat retrieval struggles with, enabling multi-hop reasoning. Yet most existing graph-based methods suffer from (i) heuristic designs lacking theoretical guarant…

Improving Instruction Following in Language Models through Proxy-Based Uncertainty Estimation

ICML 2024poster

Assessing response quality to instructions in language models is vital but challenging due to the complexity of human language across different contexts. This complexity often results in ambiguous or inconsistent interpretations, making accurate assessment difficult. To address this issue, we propos…

Unsupervised Contrastive Representation Learning for 3D Mesh Segmentation (Student Abstract)

AAAI 2023technical

3D deep learning is a growing field of interest due to the vast amount of information stored in 3D formats. Triangular meshes are an efficient representation for irregular, non-uniform 3D objects. However, meshes are often challenging to annotate due to their high computational complexity. Therefore…
