App Download Forecasting: An Evolutionary Hierarchical Competition Approach

Yingzi Wang, Nicholas Jing Yuan, Yu Sun, Chuan Qin, Xing Xie
2017 Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence  
However, most existing approaches fail to model the evolutionary competition among products and lack the capability to organically reflect multi-level competition analysis in sales forecasting.  ...  Extensive experiments using a real-world app download dataset show that EHCM outperforms state-of-the-art methods in various forecasting granularities.  ...  Therefore, we propose an Evolutionary Hierarchical Competition Model (EHCM) to model the time-evolving hierarchical competition among products and to provide more accurate product sales forecasting.  ...
