An empirical study of domain-agnostic semi-supervised learning via energy-based models: joint-training and pre-training

Yunfu Song, Huahuan Zheng, Zhijian Ou

A class of recent semi-supervised learning (SSL) methods heavily rely on domain-specific data augmentations. In contrast, generative SSL methods involve unsupervised learning based…

Neural CRF transducers for sequence labeling

Kai Hu, Zhijian Ou, Min Hu +1

Conditional random fields (CRFs) have been shown to be one of the most successful approaches to sequence labeling. Various linear-chain neural CRFs (NCRFs) are developed to impleme…

Block-Wise MAP Inference for Determinantal Point Processes with Application to Change-Point Detection

Jinye Zhang, Zhijian Ou

Existing MAP inference algorithms for determinantal point processes (DPPs) need to calculate determinants or conduct eigenvalue decomposition generally at the scale of the full ker…
