A Weakly Supervised Learning Framework for Salient Object Detection via Hybrid Labels

3 code implementations7 Sep 2022 Runmin Cong, Qi Qin, Chen Zhang, Qiuping Jiang, Shiqi Wang, Yao Zhao, Sam Kwong

In this paper, we focus on a new weakly-supervised SOD task under hybrid labels, where the supervision labels include a large number of coarse labels generated by the traditional unsupervised method and a small number of real labels.

Loop closure detection using local 3D deep descriptors

1 code implementation31 Oct 2021 Youjie Zhou, Yiming Wang, Fabio Poiesi, Qi Qin, Yi Wan

We compare our L3D-based loop closure approach with recent approaches on LiDAR data and achieve state-of-the-art loop closure detection accuracy.

HRN: A Holistic Approach to One Class Learning

1 code implementation NeurIPS 2020 Wenpeng Hu, Mengyu Wang, Qi Qin, Jinwen Ma, Bing Liu

Existing neural network based one-class learning methods mainly use various forms of auto-encoders or GAN style adversarial training to learn a latent representation of the given one class of data.

Using the Past Knowledge to Improve Sentiment Classification

no code implementations Findings of the Association for Computational Linguistics 2020 Qi Qin, Wenpeng Hu, Bing Liu

It proposes a new lifelong learning model (called L2PG) that can retain and selectively transfer the knowledge learned in the past to help learn the new task.

Text Classification with Novelty Detection

no code implementations23 Sep 2020 Qi Qin, Wenpeng Hu, Bing Liu

In this paper, we propose a significantly more effective approach that converts the original problem to a pair-wise matching problem and then outputs how probable two instances belong to the same class.

Feature Projection for Improved Text Classification

no code implementations ACL 2020 Qi Qin, Wenpeng Hu, Bing Liu

In this paper, we propose a novel angle to further improve this representation learning, i. e., feature projection.

On the Iteration Complexity Analysis of Stochastic Primal-Dual Hybrid Gradient Approach with High Probability

no code implementations22 Jan 2018 Linbo Qiao, Tianyi Lin, Qi Qin, Xicheng Lu

In this paper, we propose a stochastic Primal-Dual Hybrid Gradient (PDHG) approach for solving a wide spectrum of regularized stochastic minimization problems, where the regularization term is composite with a linear function.
