Abstract:

An overview of our ongoing projects aimed to facilitate predictive analytics in complex systems observed over time will be presented in this talk. Challenges and the proposed solutions will be discussed related to exploiting temporal dependencies among pairs of patterns in time-series subsequences for improved classification. The talk will also include discussion on how to learn a compact structure-aware representation of the attributed networks and how to capture the temporal dynamics exhibited in such networks. Reported results are based on the following papers:

• Roychoudhury, S. Zhou, F., Obradovic, Z.  “Leveraging Subsequence-orders for Univariate and Multivariate Time-series Classification,” Proc. 19^th SIAM Int’l Conf. Data Mining, Calgary, Canada, May 2019.
• Han, C., Cao, X.H., Stanojevic, M., Ghalwash, M., Obradovic, Z.  “Temporal Graph Regression via Structure-Aware Intrinsic Representation Learning,” Proc. 19^th SIAM Int’l Conf. Data Mining, Calgary, Canada, May 2019.
