報告摘要：

The big data analytics relies on advanced data mining and machine learning methods. It is important to ensure correct use of these machine learning approaches for solving a variety of real-world problems. In this talk I will present several challenges and critical problems of applying supervised learning algorithms to classification and prediction. The talk will focus on feature engineering methods, imbalanced data handling techniques and propriate evaluation criteria in supervised learning. As an example, I will introduce our new advances in data mining and machine learning, including deep learning, for quantitative structure-activity relationship (QSAR) modeling and toxicity analysis in environmental science. Additionally, I will also report our progress of deep transfer learning for pattern recognition and image classification in transportation systems and cancer diagnosis. These machine learning methods and techniques may be generalized and applied to the big data analysis in other areas.
