Report title: Data Mining and Machine seabet casino Approaches to Toxicity Analysis and Disease Prediction
Report time: 10:30 am on June 6, 2019
Reporting location: Campus Computer seabet casino 313
Lecturer: Professor Chaoyang Zhang (seabet casino of Southern Mississippi, USA)
Abstract：
The big data analytics rely on advanced data mining and machine learning methods. In this presentation I will present our current seabet casino in data mining and machine learning, and their applications in toxicology and medical science. The specificity of toxicant-target biomolecule interactions leads to the very imbalanced nature of many toxicity datasets, causing poor performance of Structure-Activity Relationship (SAR)-based chemical classification. In order to improve prediction accuracy, we propose SMOTEENNBagging, a novel ensemble resampling and learning approach, for highly imbalanced classification and also address the metric issues in model validation and performance evaluation based on the Tox21 Challenges dataset. Additionally, I will also present our progress in deep transfer learning and multi-label classification for healthcare risk prediction and cancer diagnosis. These machine learning methods and techniques may be generalized and applied to the data analysis in other areas.
