From Graph to Word Bag: Introducing Domain Knowledge to Confusing Charge Prediction

1 code implementation7 Mar 2024 Ang Li, Qiangchao Chen, Yiquan Wu, Ming Cai, Xiang Zhou, Fei Wu, Kun Kuang

In this paper, we introduce a novel From Graph to Word Bag (FWGB) approach, which introduces domain knowledge regarding constituent elements to guide the model in making judgments on confusing charges, much like a judge's reasoning process.

Enhancing Court View Generation with Knowledge Injection and Guidance

1 code implementation7 Mar 2024 Ang Li, Yiquan Wu, Yifei Liu, Fei Wu, Ming Cai, Kun Kuang

Court View Generation (CVG) is a challenging task in the field of Legal Artificial Intelligence (LegalAI), which aims to generate court views based on the plaintiff claims and the fact descriptions.

Adversarial Masking Contrastive Learning for vein recognition

no code implementations16 Jan 2024 Huafeng Qin, Yiquan Wu, Mounim A. El-Yacoubi, Jun Wang, Guangxiang Yang

To overcome this problem, in this paper, we propose an adversarial masking contrastive learning (AMCL) approach, that generates challenging samples to train a more robust contrastive learning model for the downstream palm-vein recognition task, by alternatively optimizing the encoder in the contrastive learning model and a set of latent variables.

Precedent-Enhanced Legal Judgment Prediction with LLM and Domain-Model Collaboration

no code implementations13 Oct 2023 Yiquan Wu, Siying Zhou, Yifei Liu, Weiming Lu, Xiaozhong Liu, Yating Zhang, Changlong Sun, Fei Wu, Kun Kuang

Precedents are the previous legal cases with similar facts, which are the basis for the judgment of the subsequent case in national legal systems.

Attentional Local Contrast Networks for Infrared Small Target Detection

2 code implementations15 Dec 2020 Yimian Dai, Yiquan Wu, Fei Zhou, Kobus Barnard

To mitigate the issue of minimal intrinsic features for pure data-driven methods, in this paper, we propose a novel model-driven deep network for infrared small target detection, which combines discriminative networks and conventional model-driven methods to make use of both labeled data and the domain knowledge.

Asymmetric Contextual Modulation for Infrared Small Target Detection

4 code implementations30 Sep 2020 Yimian Dai, Yiquan Wu, Fei Zhou, Kobus Barnard

Single-frame infrared small target detection remains a challenge not only due to the scarcity of intrinsic target characteristics but also because of lacking a public dataset.

Attentional Feature Fusion

2 code implementations29 Sep 2020 Yimian Dai, Fabian Gieseke, Stefan Oehmcke, Yiquan Wu, Kobus Barnard

Feature fusion, the combination of features from different layers or branches, is an omnipresent part of modern network architectures.

Attention as Activation

1 code implementation15 Jul 2020 Yimian Dai, Stefan Oehmcke, Fabian Gieseke, Yiquan Wu, Kobus Barnard

Inspired by their similarity, we propose a novel type of activation units called attentional activation (ATAC) units as a unification of activation functions and attention mechanisms.

Laplacian regularized low rank subspace clustering

no code implementations24 Oct 2016 Yu Song, Yiquan Wu

This problem is solved in the low rank subspace clustering model which decomposes the corrupted data matrix as the sum of a clean and self-expressive dictionary plus a matrix of noise and gross errors.

Clustering

Subspace clustering based on low rank representation and weighted nuclear norm minimization

no code implementations12 Oct 2016 Yu Song, Yiquan Wu

Subspace clustering refers to the problem of segmenting a set of data points approximately drawn from a union of multiple linear subspaces.
