BeyondGender: A Multifaceted Bilingual Dataset for Practical Sexism Detection

AAAI 2025technical

Sexism affects both women and men, yet research often overlooks misandry and suffers from overly broad annotations that limit AI applications. To address this, we introduce BeyondGender, a dataset meticulously annotated according to the latest definitions of misogyny and misandry. It features innova…

Can Many-Shot In-Context Learning Help LLMs as Evaluators? A Preliminary Empirical Study

COLING 2025main

Utilizing Large Language Models (LLMs) as evaluators to assess the performance of other LLMs has garnered attention. However, this evaluation approach is affected by potential biases within LLMs, raising concerns about the accuracy and reliability of the evaluation results of LLMs. To address this i…

Counting-Stars: A Multi-evidence, Position-aware, and Scalable Benchmark for Evaluating Long-Context Large Language Models

COLING 2025main

Despite recent efforts to develop large language models with robust long-context capabilities, the lack of long-context benchmarks means that relatively little is known about their performance. To alleviate this gap, in this paper, we propose Counting-Stars, a multi-evidence, position-aware, and sca…

FastCuRL: Curriculum Reinforcement Learning with Stage-wise Context Scaling for Efficient Training R1-like Reasoning Models

EMNLP 2025

Improving training efficiency continues to be one of the primary challenges in large-scale Reinforcement Learning (RL). In this paper, we investigate how context length and the complexity of training data influence the RL scaling training process of R1-distilled reasoning models, e.g., DeepSeek-R1-D

Global Motion Corresponder for 3D Point-Based Scene Interpolation under Large Motion

ICCV 2025poster

Existing dynamic scene interpolation methods typically assume that the motion between consecutive timesteps is small enough so that displacements can be locally approximated by linear models. In practice, even slight deviations from this small-motion assumption can cause conventional techniques to f…

Learning Efficient Fuse-and-Refine for Feed-Forward 3D Gaussian Splatting

NeurIPS 2025poster

Recent advances in feed-forward 3D Gaussian Splatting have led to rapid improvements in efficient scene reconstruction from sparse views. However, most existing approaches construct Gaussian primitives directly aligned with the pixels in one or more of the input images. This leads to redundancies in…

Scaling Transformer-Based Novel View Synthesis with Models Token Disentanglement and Synthetic Data

ICCV 2025poster

Large transformer-based models have made significant progress in generalizable novel view synthesis (NVS) from sparse input views, generating novel viewpoints without the need for test-time optimization. However, these models are constrained by the limited diversity of publicly available scene datas…

Learning 1D Causal Visual Representation with De-focus Attention Networks

NeurIPS 2024poster

Modality differences have led to the development of heterogeneous architectures for vision and language models. While images typically require 2D non-causal modeling, texts utilize 1D causal modeling. This distinction poses significant challenges in constructing unified multi-modal models. This pape…

STOA-VLP: Spatial-Temporal Modeling of Object and Action for Video-Language Pre-training

AAAI 2023technical

Although large-scale video-language pre-training models, which usually build a global alignment between the video and the text, have achieved remarkable progress on various downstream tasks, the idea of adopting fine-grained information during the pre-training stage is not well explored. In this wor…

Masked Language Models Know Which are Popular: A Simple Ranking Strategy for Commonsense Question Answering

EMNLP 2022finding

We propose a simple ranking strategy to solve a generative commonsense question answering (QA) problem. Compared with multiple-choice QA, it is challenging because the answers to a question are not unique and they are supposed to be popular and diverse. Our strategy exploits the dataset itself and n…

StyleSDF: High-Resolution 3D-Consistent Image and Geometry Generation

CVPR 2022oral

We introduce a high resolution, 3D-consistent image and shape generation technique which we call StyleSDF. Our method is trained on single view RGB data only, and stands on the shoulders of StyleGAN2 for image generation, while solving two main challenges in 3D-aware GANs: 1) high-resolution, view-c…

Embedded Discriminative Attention Mechanism for Weakly Supervised Semantic Segmentation

CVPR 2021poster

Weakly Supervised Semantic Segmentation (WSSS) with image-level annotation uses class activation maps from the classifier as pseudo-labels for semantic segmentation. However, such activation maps usually highlight the local discriminative regions rather than the whole object, which deviates from the…
