Abstract
Click rate prediction of hot topics contributes to get event tendency, especially for sensitive news. However, click rate prediction is challenge due to inherent features of short-time series such as randomness, uncertainty, volatility and insufficiency of training samples. In this paper, a new hybrid click rate prediction method called Grey Verhulst—Extreme Learning Machine (GVELM) is proposed. Specifically, the raw short-time series data are filled into GV models to acquire stably initial prediction which have incorporated regular pattern of the historic data without noise. Then ELM is employed for prediction refinement for nonlinear space mapping. The experimental results show that the proposed method achieves better prediction accuracy compared with other five state-of-art algorithms.
