Generating precise class-aware pseudo ground-truths, a.k.a, class activation maps (CAMs), is essential for Weakly-Supervised Semantic Segmentation. The original CAM method usually produces incomplete and inaccurate localization maps. To tackle with this issue, this paper proposes an Expansion and Sh…

URetinex-Net: Retinex-Based Deep Unfolding Network for Low-Light Image Enhancement

CVPR 2022poster

Retinex model-based methods have shown to be effective in layer-wise manipulation with well-designed priors for low-light image enhancement. However, the commonly used hand-crafted priors and optimization-driven solutions lead to the absence of adaptivity and efficiency. To address these issues, in…

FCM: A Fine-grained Comparison Model for Multi-turn Dialogue Reasoning

EMNLP 2021finding

Despite the success of neural dialogue systems in achieving high performance on the leader-board, they cannot meet users’ requirements in practice, due to their poor reasoning skills. The underlying reason is that most neural dialogue models only capture the syntactic and semantic information, but f…

Integrating Subgraph-Aware Relation and Direction Reasoning for Question Answering

ICASSP 2021accepted

Question Answering (QA) models over Knowledge Bases (KBs) are capable of providing more precise answers by utilizing relation information among entities. Although effective, most of these models solely rely on fixed relation representations to obtain answers for different question-related KB subgrap…

Modelling Long-distance Node Relations for KBQA with Global Dynamic Graph

COLING 2020main

The structural information of Knowledge Bases (KBs) has proven effective to Question Answering (QA). Previous studies rely on deep graph neural networks (GNNs) to capture rich structural information, which may not model node relations in particularly long distance due to oversmoothing issue. To addr…

Exploiting Local and Global Structure for Point Cloud Semantic Segmentation with Contextual Point Representations

NeurIPS 2019poster

In this paper, we propose one novel model for point cloud semantic segmentation,which exploits both the local and global structures within the point cloud based onthe contextual point representations. Specifically, we enrich each point represen-tation by performing one novel gated fusion on the poin…

Fast Coding Unit Decision for Intra Screen Content Coding Based on Ensemble Learning

ICASSP 2019accepted

The Screen Content Coding (SCC) is an extension of High Efficiency Video Coding (HEVC), and it achieves significant improvement on compression ratio. However, the obtained coding efficiency is at the cost of high computational complexity. In this paper, to reduce the computation complexity, we propo…

Learning to Explore Intrinsic Saliency for Stereoscopic Video

CVPR 2019poster

The human visual system excels at biasing the stereoscopic visual signals by the attention mechanisms. Traditional methods relying on the low-level features and depth relevant information for stereoscopic video saliency prediction have fundamental limitations. For example, it is cumbersome to model…
