Ke Yan is currently an assistant professor with the department of Building, School of Design and Environment, National University of Singapore (NUS). He is also a visiting professor of the Waseda University, Tokyo, Japan and Huaqiao University, China. Dr. Yan is largely engaged in cross-discipline research fields, including machine learning, artificial intelligence, cyber intelligence, applied mathematics, sustainability and applied energy. He is actively involved with multiple highly-ranked journals’ editorial boards, such as the IEEE Transactions on Industrial Informatics (TII) and IEEE/ACM Transactions on Computational Biology and Bioinformatics. He has published more than 70 full length papers with highly ranked conferences and journals, including Association for the Advancement of Artificial Intelligence (AAAI), IEEE Transactions on Industrial Informatics (TII), IEEE Transactions on Sustainable Energy (TSE), IEEE Transactions on Systems, Man and Cybernetics: Systems (SMCA) and Applied Energy (AE).
The high development of emerging computing paradigms, such as Ubiquitous Computing, Mobile Computing, and Social Computing, has brought us a big change from all walks of our work, life, learning and entertainment. Especially, with the high accessibility of social networking services, more and more populations have been engaged into this kind of integration of real physical world and cyber digital space. In this talk, we concentrate on personalized big data analytics in cyber-social computing applications, specifically, discuss the research on scholarly big data, which is a large-scale collection of academic information, technical data, and collaboration relationships.Mechanisms and algorithms are introduced to facilitate the adoption of social computing paradigm that made it easier for researchers to join collaborative research activities and share academic data across the highly interlaced cyber-social networks.
Artificial intelligence (AI) technologies, including machine learning (ML) and deep learning (DL), bring the great advantage in forecasting to various applications of time series analysis. In the seminar, first, we will introduce the fundamental knowledge of time series data and time series analysis. Traditional methods, such as the regression analysis and moving average model are introduced. Then, real-world time series applications, including energy consumption forecasting, solar energy PV system optimization and air quality forecasting, will be visited in this seminar. Last, the cutting-edge AI techniques, such as the bidirectional long short term memory (BiLSTM) and the nested long short term memory (NLSTM) neural networks, are presented to show the advantages over traditional ML and DL approaches. A wavelet-transform based data decomposition and a multi-tasking neural network structure are designed for better performances in forecasting.
