3D Question Answering via only 2D Vision-Language Models

ICML 2025poster

Large vision-language models (LVLMs) have significantly advanced numerous fields. In this work, we explore how to harness their potential to address 3D scene understanding tasks, using 3D question answering (3D-QA) as a representative example. Due to the limited training data in 3D, we do not train…

Frame-Voyager: Learning to Query Frames for Video Large Language Models

ICLR 2025poster

Video Large Language Models (Video-LLMs) have made remarkable progress in video understanding tasks. However, they are constrained by the maximum length of input tokens, making it impractical to input entire videos. Existing frame selection approaches, such as uniform frame sampling and text-frame r…

Outdoor Monocular SLAM with Global Scale-Consistent 3D Gaussian Pointmaps

ICCV 2025poster

3D Gaussian Splatting (3DGS) has become a popular solution in SLAM due to its high-fidelity and real-time novel view synthesis performance. However, some previous 3DGS SLAM methods employ a differentiable rendering pipeline for tracking, lack geometric priors in outdoor scenes. Other approaches intr…

RGB-Only Gaussian Splatting SLAM for Unbounded Outdoor Scenes

ICRA 2025

3D Gaussian Splatting (3DGS) has become a popular solution in SLAM, as it can produce high-fidelity novel views. However, previous GS-based methods primarily target indoor scenes and rely on RGB-D sensors or pretrained depth estimation models, hence underperforming in outdoor scenarios. To address t

RegGS: Unposed Sparse Views Gaussian Splatting with 3DGS Registration

ICCV 2025poster

3D Gaussian Splatting (3DGS) has demonstrated its potential in reconstructing scenes from unposed images. However, optimization-based 3DGS methods struggle with sparse views due to limited prior knowledge. Meanwhile, feed-forward Gaussian approaches are constrained by input formats, making it challe…

Reverse Modeling in Large Language Models

NAACL 2025short

Humans are accustomed to reading and writing in a forward manner, and this natural bias extends to text understanding in auto-regressive large language models (LLMs). This paper investigates whether LLMs, like humans, struggle with reverse modeling, specifically with reversed text inputs. We found t…

Sparse-to-Dense: A Free Lunch for Lossless Acceleration of Video Understanding in LLMs

ACL 2025short

Due to the auto-regressive nature of current video large language models (Video-LLMs), the inference latency increases as the input sequence length grows, posing challenges for the efficient processing of video sequences that are usually very long. We observe that during decoding, the attention scor…

TKA-MIL: Top-K Attention Multiple Instance Learning for Whole Slide Image Classification and Instance Probability Derivation

ICASSP 2025accepted

Multiple instance learning (MIL) has been increasingly applied to the classification of histopathology whole slide images (WSI). While many classic attention-based MIL algorithms have achieved good classification performance, they do not account for the relationships between instances. Using transfo…

GliDe with a CaPE: A Low-Hassle Method to Accelerate Speculative Decoding

ICML 2024poster

Speculative decoding is a relatively new decoding framework that leverages small and efficient draft models to reduce the latency of LLMs. In this study, we introduce GliDe and CaPE, two low-hassle modifications to vanilla speculative decoding to further improve the decoding speed of a frozen LLM. S…

Context Modeling with Evidence Filter for Multiple Choice Question Answering

ICASSP 2022accepted

Multiple-Choice Question Answering (MCQA) is one of the challenging tasks in machine reading comprehension. The main challenge in MCQA is to extract "evidence" from the given context that supports the correct answer. In OpenbookQA dataset [1], the requirement of extracting "evidence" is particularly…

Interventional Training for Out-Of-Distribution Natural Language Understanding

EMNLP 2022main

Out-of-distribution (OOD) settings are used to measure a model’s performance when the distribution of the test data is different from that of the training data. NLU models are known to suffer in OOD. We study this issue from the perspective of causality, which sees confounding bias as the reason for…

COSY: COunterfactual SYntax for Cross-Lingual Understanding

ACL 2021long

Pre-trained multilingual language models, e.g., multilingual-BERT, are widely used in cross-lingual tasks, yielding the state-of-the-art performance. However, such models suffer from a large performance gap between source and target languages, especially in the zero-shot setting, where the models ar…
