VisualPuzzles: Decoupling Multimodal Reasoning Evaluation from Domain Knowledge

no code implementations14 Apr 2025 Yueqi Song, Tianyue Ou, Yibo Kong, Zecheng Li, Graham Neubig, Xiang Yue

Current multimodal benchmarks often conflate reasoning with domain-specific knowledge, making it difficult to isolate and evaluate general reasoning abilities in non-expert settings.

Scaling up Multimodal Pre-training for Sign Language Understanding

no code implementations16 Aug 2024 Wengang Zhou, Weichao Zhao, Hezhen Hu, Zecheng Li, Houqiang Li

To facilitate communication between the deaf-mute and hearing people, a series of sign language understanding (SLU) tasks have been studied in recent years, including isolated/continuous sign language recognition (ISLR/CSLR), gloss-free sign language translation (GF-SLT) and sign language retrieval (SL-RT).

SEDS: Semantically Enhanced Dual-Stream Encoder for Sign Language Retrieval

1 code implementation23 Jul 2024 Longtao Jiang, Min Wang, Zecheng Li, Yao Fang, Wengang Zhou, Houqiang Li

Furthermore, existing RGB-based sign retrieval works suffer from the huge memory cost of dense visual data embedding in end-to-end training, and adopt offline RGB encoder instead, leading to suboptimal feature representation.

Complete Instances Mining for Weakly Supervised Instance Segmentation

1 code implementation International Joint Conference on Artificial Intelligence 2023 Zecheng Li, Zening Zeng, Yuqi Liang, Jin-Gang Yu

To address this problem, we propose a novel approach for WSIS that focuses on the online refinement of complete instances through the use of MaskIoU heads to predict the integrity scores of proposals and a Complete Instances Mining (CIM) strategy to explicitly model the redundant segmentation problem and generate refined pseudo labels.
