主 题：Purchase Prediction in Online Chat Service with a Novel Cross-attention Mechanism in LSTM-based Networks
主讲人：汪雅婧 博士生
主持人：徐云杰 教 授
摘 要：
Online-chat has emerged as important type of service firms and customers. However, the rich interaction information in the online-chat text is still under-utilized. We design a novel cross-attention mechanism to predict consumer purchase behavior based on the chat text. Experiment suggests that a cross-attention mechanism is superior to self-attention and the performance of the algorithm reaches 0.84 by AUC. Ablation study shows that the external attention is more important than internal attention in predicting purchase behavior. Our experiment shows that applying cross-attention to LSTM network is a suitable technique for the management of chat-based online customer service.
