Few-shot Image Classification based on Gradual Machine Learning

no code implementations28 Jul 2023 Na Chen, Xianming Kuang, Feiyu Liu, Kehao Wang, Qun Chen

Specifically, our proposed solution extracts indicative feature representations by deep backbones, and then constructs both unary and binary factors based on the extracted features to facilitate gradual learning.

Active Deep Learning on Entity Resolution by Risk Sampling

no code implementations23 Dec 2020 Youcef Nafa, Qun Chen, Zhaoqiang Chen, Xingyu Lu, Haiyang He, Tianyi Duan, Zhanhuai Li

Building upon the recent advances in risk analysis for ER, which can provide a more refined estimate on label misprediction risk than the simpler classifier outputs, we propose a novel AL approach of risk sampling for ER.

Adaptive Deep Learning for Entity Resolution by Risk Analysis

no code implementations7 Dec 2020 Zhaoqiang Chen, Qun Chen, Youcef Nafa, Tianyi Duan, Wei Pan, Lijun Zhang, Zhanhuai Li

Built on the recent advances on risk analysis for ER, the proposed approach first trains a deep model on labeled training data, and then fine-tunes it by minimizing its estimated misprediction risk on unlabeled target data.

Gradual Machine Learning for Aspect-level Sentiment Analysis

no code implementations6 Jun 2019 Yanyan Wang, Qun Chen, Jiquan Shen, Boyi Hou, Murtadha Ahmed, Zhanhuai Li

The state-of-the-art solutions for Aspect-Level Sentiment Analysis (ALSA) were built on a variety of deep neural networks (DNN), whose efficacy depends on large amounts of accurately labeled training data.

Gradual Machine Learning for Entity Resolution

no code implementations29 Oct 2018 Boyi Hou, Qun Chen, Yanyan Wang, Youcef Nafa, Zhanhuai Li

Using ER as a test case, we demonstrate that gradual machine learning is a promising paradigm potentially applicable to other challenging classification tasks requiring extensive labeling effort.
