TagSplat: Topology-Aware Gaussian Splatting for Dynamic Mesh Modeling and Tracking

CVPR 2026

Topology-consistent dynamic model sequences are essential for applications such as animation and model editing. However, existing 4D reconstruction methods face challenges in generating high-quality topology-consistent meshes. To address this, we propose a topology-aware dynamic reconstruction frame

FaithBench: A Diverse Hallucination Benchmark for Summarization by Modern LLMs

NAACL 2025short

Summarization is one of the most common tasks performed by large language models (LLMs), especially in applications like Retrieval-Augmented Generation (RAG). However, existing evaluations of hallucinations in LLM-generated summaries, and evaluations of hallucination detection models both suffer fro…

Computational Complexity of Asynchronous Policy Iteration for Two-Player Zero-Sum Markov Games

ICASSP 2024accepted

Bertsekas recently proposed Asynchronous Policy Iteration (API) as an alternative algorithm of Policy Iteration (PI) for solving the problem of two-player zero-sum Markov games. To quantifying the benefits of API, besides its flexibility for parallel and asynchronous implementation, the focus of thi…

SummaCoz: A Dataset for Improving the Interpretability of Factual Consistency Detection for Summarization

EMNLP 2024finding

Summarization is an important application of Large Language Models (LLMs). When judging the quality of a summary, factual consistency holds a significant weight. Despite numerous efforts dedicated to building factual inconsistency detectors, the exploration of explanability remains limited among exi…
