Introduction We investigate various problems and challenges regarding fact-checking and fake news classification tasks. Some of the problems are: user endogeneous preference encoding, zero/few-shot fake news detection, and fake news detection under adversarial settings.

Introduction The adversarial behaviors between advanced spammers and the defenders make the fraud detection problem more challenging. We employ various machine learning methods to simulate the adversarial behavior between two sides and devise robust fraud detectors.

- Securing Graph-based Learning Models
Introduction Despite the advance of graph-based learning models like probabilistic graphical models and graph neural networks, their applications to various areas also face diverse threats. We investigate the practical threats of SOTA models and secure them from multiple channels.

- Suspicious Behavior Modeling in Mobile App Markets
Introduction Mobile App Markets like App Store and Google Play involves many fraudsters like spammers, botnets and crowd workers. We investigate the underground market of trading app downloads and reviews, and aim to design classifers with multi-view and multi-source information according to the intention of the fraudsters.
