Deep Generative Modeling on Limited Data with Regularization by Nontransferable Pre-trained Models

1 code implementation30 Aug 2022 Yong Zhong, Hongtao Liu, Xiaodong Liu, Fan Bao, Weiran Shen, Chongxuan Li

Deep generative models (DGMs) are data-eager because learning a complex model on limited data suffers from a large variance and easily overfits.

Going Negative Online? -- A Study of Negative Advertising on Social Media

no code implementations14 Oct 2019 Hongtao Liu

This research collects the data of the related political ads in the context of the U. S. midterm elections since August to study the overall pattern of political ads on social media and uses sets of machine learning methods to conduct sentiment analysis on these ads to classify the negative ads.
