MTRec: Multi-Task Learning over BERT for News Recommendation

1 code implementation Findings (ACL) 2022 Qiwei Bi, Jian Li, Lifeng Shang, Xin Jiang, Qun Liu, Hanfang Yang

With the adoption of large pre-trained models like BERT in news recommendation, the above way to incorporate multi-field information may encounter challenges: the shallow feature encoding to compress the category and entity information is not compatible with the deep BERT encoding.

Boosted Histogram Transform for Regression

no code implementations ICML 2020 Yuchao Cai, Hanyuan Hang, Hanfang Yang, Zhouchen Lin

In this paper, we propose a boosting algorithm for regression problems called \textit{boosted histogram transform for regression} (BHTR) based on histogram transforms composed of random rotations, stretchings, and translations.

Bagged Regularized $k$-Distances for Anomaly Detection

no code implementations2 Dec 2023 Yuchao Cai, Yuheng Ma, Hanfang Yang, Hanyuan Hang

We consider the paradigm of unsupervised anomaly detection, which involves the identification of anomalies within a dataset in the absence of labeled examples.

Under-bagging Nearest Neighbors for Imbalanced Classification

no code implementations1 Sep 2021 Hanyuan Hang, Yuchao Cai, Hanfang Yang, Zhouchen Lin

In this paper, we propose an ensemble learning algorithm called \textit{under-bagging $k$-nearest neighbors} (\textit{under-bagging $k$-NN}) for imbalanced classification problems.

Gradient Boosted Binary Histogram Ensemble for Large-scale Regression

no code implementations3 Jun 2021 Hanyuan Hang, Tao Huang, Yuchao Cai, Hanfang Yang, Zhouchen Lin

In this paper, we propose a gradient boosting algorithm for large-scale regression problems called \textit{Gradient Boosted Binary Histogram Ensemble} (GBBHE) based on binary histogram partition and ensemble learning.
