REN R 690 - Multivariate Statistics and Machine Learning for the Environmental Sciences

Course instructor: Dr. Andreas Hamann, GSB 733, 492-6429, andreas.hamann@ualberta.ca.

Location & Time: Winter Terms, GSB 866, Wednesdays 9am to 12pm, extra labs & meetings TBA.

Online version: This course is the online equivalent of course REN R 960, tought at the University of Alberta. If you want to "audit" the class, or could not enroll because the class was full, you may use the self-study material below. Covers methods for visualization, analysis and prediction for complex biological or environmental data. Includes classical and modern approaches to ordination and classification, analysis of multivariate relationships, and the application of deep neural networks and other machine learning tools for prediction. Participants engage in problem-based learning by analyzing data from their thesis research project.

Registered students: If you take REN R 690 for credit, then log into the University of Alberta eClass section for this course instead: http://tinyurl.com/mv690/eclass
