Anomaly Detection with Score Distribution Discrimination

1 code implementation26 Jun 2023 Minqi Jiang, Songqiao Han, Hailiang Huang

In this paper, we propose to optimize the anomaly scoring function from the view of score distribution, thus better retaining the diversity and more fine-grained information of input data, especially when the unlabeled data contains anomaly noises in more practical AD scenarios.

IDEA: Interactive DoublE Attentions from Label Embedding for Text Classification

no code implementations23 Sep 2022 Ziyuan Wang, Hailiang Huang, Songqiao Han

Current text classification methods typically encode the text merely into embedding before a naive or complicated classifier, which ignores the suggestive information contained in the label text.

Label Confusion Learning to Enhance Text Classification Models

1 code implementation9 Dec 2020 Biyang Guo, Songqiao Han, Xiao Han, Hailiang Huang, Ting Lu

LCM can learn label confusion to capture semantic overlap among labels by calculating the similarity between instances and labels during training and generate a better label distribution to replace the original one-hot label vector, thus improving the final classification performance.
