Spectrum-based deep neural networks for fraud detection
Shuhan Yuan, Xintao Wu, Jun Li +1
In this paper, we focus on fraud detection on a signed graph with only a small set of labeled training data. We propose a novel framework that combines deep neural networks and spe…
Wikipedia Vandal Early Detection: from User Behavior to User Embedding
Shuhan Yuan, Panpan Zheng, Xintao Wu +1
Wikipedia is the largest online encyclopedia that allows anyone to edit articles. In this paper, we propose the use of deep learning to detect vandals based on their edit history.…
Task-specific Word Identification from Short Texts Using a Convolutional Neural Network
Shuhan Yuan, Xintao Wu, Yang Xiang
Task-specific word identification aims to choose the task-related words that best describe a short text. Existing approaches require well-defined seed words or lexical dictionaries…
SNE: Signed Network Embedding
Shuhan Yuan, Xintao Wu, Yang Xiang
Several network embedding models have been developed for unsigned networks. However, these models based on skip-gram cannot be applied to signed networks because they can only deal…
