Keyword Augmentation via Generative Methods

no code implementations ACL (ECNLP) 2021 Haoran Shi, Zhibiao Rao, Yongning Wu, Zuohua Zhang, Chu Wang

In this paper, we propose a keyword augmentation method based on generative seq2seq model and trie-based search mechanism, which is able to generate high-quality keywords for any products or product lists.

Dynamic Gaussian Graph Operator: Learning parametric partial differential equations in arbitrary discrete mechanics problems

no code implementations5 Mar 2024 Chu Wang, Jinhong Wu, Yanzhi Wang, Zhijian Zha, Qi Zhou

Metric vectors are regarded as located on latent uniform domain, wherein spatial and spectral transformation offer highly regular constraints on solution space.

IH-ViT: Vision Transformer-based Integrated Circuit Appear-ance Defect Detection

no code implementations9 Feb 2023 Xiaoibin Wang, Shuang Gao, Yuntao Zou, Jianlan Guo, Chu Wang

For the problems of low recognition rate and slow recognition speed of traditional detection methods in IC appearance defect detection, we propose an IC appearance defect detection algo-rithm IH-ViT.

Dominant Set Clustering and Pooling for Multi-View 3D Object Recognition

1 code implementation4 Jun 2019 Chu Wang, Marcello Pelillo, Kaleem Siddiqi

We improve upon these methods by introducing a view clustering and pooling layer based on dominant sets.

FAN: Focused Attention Networks

no code implementations27 May 2019 Chu Wang, Babak Samari, Vladimir Kim, Siddhartha Chaudhuri, Kaleem Siddiqi

Thus far the learning of attention weights has been driven solely by the minimization of task specific loss functions.

Local Spectral Graph Convolution for Point Set Feature Learning

1 code implementation ECCV 2018 Chu Wang, Babak Samari, Kaleem Siddiqi

In the present article, we propose to overcome this limitation by using spectral graph convolution on a local graph, combined with a novel graph pooling strategy.

A New Family of Near-metrics for Universal Similarity

no code implementations21 Jul 2017 Chu Wang, Iraj Saniee, William S. Kennedy, Chris A. White

We show that for structured data including categorical and continuous data, the near-metrics corresponding to normalized forward k-step diffusion (k small) work as one of the best performing similarity measures; for vector representations of text and images including those extracted from deep learning, the near-metrics derived from normalized and reverse k-step graph diffusion (k very small) exhibit outstanding ability to distinguish data points from different classes.

Self-Sustaining Iterated Learning

no code implementations13 Sep 2016 Bernard Chazelle, Chu Wang

An important result from psycholinguistics (Griffiths & Kalish, 2005) states that no language can be learned iteratively by rational agents in a self-sustaining manner.

Functional Frank-Wolfe Boosting for General Loss Functions

no code implementations9 Oct 2015 Chu Wang, Yingfei Wang, Weinan E, Robert Schapire

Yet, as the number of base hypotheses becomes larger, boosting can lead to a deterioration of test performance.

The Knowledge Gradient with Logistic Belief Models for Binary Classification

no code implementations8 Oct 2015 Yingfei Wang, Chu Wang, Warren Powell

We consider sequential decision making problems for binary classification scenario in which the learner takes an active role in repeatedly selecting samples from the action pool and receives the binary label of the selected alternatives.
