Supervised and Unsupervised Learning on Temporal Data Analytical Applications
PhD Thesis Proposal Defence Title: "Supervised and Unsupervised Learning on Temporal Data Analytical Applications" by Mr. Fengchao PENG Abstract: Temporal data analysis has been widely applied in various areas, such as bio-informatics, outlier detection, and trajectory analysis. Different applications require a variety of machine learning methods. In this thesis proposal, we study the supervised and unsupervised learning methods in temporal data analytical applications. We first develop a time series classification method that is effective and efficient in monitoring devices that are used in wireless communication. We use active learning method to reduce the labeling cost when collecting training data. And we use Random Forest and Bootstrap methods to solve the label imbalance problem. Then we propose a novel active learning method for time series classification. The method adapts the idea of shapelet discovery and select the training data based on both the uncertainty of classifier and the utility of each data instance. Finally we study the problem of team strategy detection which is an important problem in team sport games. We propose an unsupervised method to identify trajectory patterns that match with frequently used team strategies.
