Evaluating Hierarchical Document Categorisation

no code implementations ALTA 2021 Qian Sun, Aili Shen, Hiyori Yoshikawa, Chunpeng Ma, Daniel Beck, Tomoya Iwakura, Timothy Baldwin

Hierarchical document categorisation is a special case of multi-label document categorisation, where there is a taxonomic hierarchy among the labels.

Semi-Weakly Supervised Object Kinematic Motion Prediction

no code implementations CVPR 2023 Gengxin Liu, Qian Sun, Haibin Huang, Chongyang Ma, Yulan Guo, Li Yi, Hui Huang, Ruizhen Hu

First, although 3D dataset with fully annotated motion labels is limited, there are existing datasets and methods for object part semantic segmentation at large scale.

Search By Image: Deeply Exploring Beneficial Features for Beauty Product Retrieval

no code implementations24 Mar 2023 Mingqiang Wei, Qian Sun, Haoran Xie, Dong Liang, Fu Lee Wang

Searching by image is popular yet still challenging due to the extensive interference arose from i) data variations (e. g., background, pose, visual angle, brightness) of real-world captured images and ii) similar images in the query dataset.


OPE-SR: Orthogonal Position Encoding for Designing a Parameter-free Upsampling Module in Arbitrary-scale Image Super-Resolution

no code implementations CVPR 2023 Gaochao Song, Luo Zhang, Ran Su, Jianfeng Shi, Ying He, Qian Sun

Motivated by position encoding, we propose orthogonal position encoding (OPE) - an extension of position encoding - and an OPE-Upscale module to replace the INR-based upsampling module for arbitrary-scale image super-resolution.

Semantic Segmentation by Improved Generative Adversarial Networks

no code implementations20 Apr 2021 ZengShun Zhaoa, Yulong Wang, Ke Liu, Haoran Yang, Qian Sun, Heng Qiao

Besides, the adversarial loss aggressively encourages the output image to be close to the distribution of the ground truth.

Superpixel Segmentation with Fully Convolutional Networks

1 code implementation CVPR 2020 Fengting Yang, Qian Sun, Hailin Jin, Zihan Zhou

In computer vision, superpixels have been widely used as an effective way to reduce the number of image primitives for subsequent processing.

Stochastic Coordinate Coding and Its Application for Drosophila Gene Expression Pattern Annotation

no code implementations30 Jul 2014 Binbin Lin, Qingyang Li, Qian Sun, Ming-Jun Lai, Ian Davidson, Wei Fan, Jieping Ye

The effectiveness of gene expression pattern annotation relies on the quality of feature representation.

A Two-Stage Weighting Framework for Multi-Source Domain Adaptation

no code implementations NeurIPS 2011 Qian Sun, Rita Chattopadhyay, Sethuraman Panchanathan, Jieping Ye

In this paper we propose a two-stage domain adaptation methodology which combines weighted data from multiple sources based on marginal probability differences (first stage) as well as conditional probability differences (second stage), with the target domain data.
