Local Probabilistic Model for Bayesian Classification: a Generalized Local Classification Model

no code implementations13 Dec 2018 Chengsheng Mao, Lijuan Lu, Bin Hu

In this paper, with the insight that the distribution in a local sample space should be simpler than that in the whole sample space, a local probabilistic model established for a local region is expected much simpler and can relax the fundamental assumptions that may not be true in the whole sample space.

Local Distribution in Neighborhood for Classification

no code implementations7 Dec 2018 Chengsheng Mao, Bin Hu, Lei Chen, Philip Moore, Xiaowei Zhang

Additionally, based on the local distribution, we generate a generalized local classification form that can be effectively applied to various datasets through tuning the parameters.

Distribution Networks for Open Set Learning

no code implementations20 Sep 2018 Chengsheng Mao, Liang Yao, Yuan Luo

In this paper, we recognize that novel classes should be different from each other, and propose distribution networks for open set learning that can model different novel classes based on probability distributions.

Deep Generative Classifiers for Thoracic Disease Diagnosis with Chest X-ray Images

1 code implementation20 Sep 2018 Chengsheng Mao, Yiheng Pan, Zexian Zeng, Liang Yao, Yuan Luo

However, most of the previous deep neural network classifiers were based on deterministic architectures which are usually very noise-sensitive and are likely to aggravate the overfitting issue.

Graph Convolutional Networks for Text Classification

7 code implementations15 Sep 2018 Liang Yao, Chengsheng Mao, Yuan Luo

We build a single text graph for a corpus based on word co-occurrence and document word relations, then learn a Text Graph Convolutional Network (Text GCN) for the corpus.
