Explainable Deep Behavioral Sequence Clustering for Transaction Fraud Detection

no code implementations12 Jan 2021 Wei Min, Weiming Liang, Hang Yin, Zhurong Wang, Mei Li, Alok Lal

To utilize the behavior sequence data, we treat click stream data as event sequence, use time attention based Bi-LSTM to learn the sequence embedding in an unsupervised fashion, and combine them with intuitive features generated by risk experts to form a hybrid feature representation.
