3rd Summer Institute in Statistics for Big Data

Module 5: Unsupervised Methods for Statistical Machine Learning

Week 3, Session 5, Monday 8:30 AM - Wednesday 12:00 PM: Mon Jul 24 to Wed Jul 26

In this module, we will present a number of unsupervised learning techniques for finding patterns and associations in Biomedical Big Data. These include dimension reduction techniques such as principal components analysis and non-negative matrix factorization, clustering analysis, and network analysis with graphical models.

We will also discuss large-scale inference issues, such as multiple testing, that arise when mining for associations in Biomedical Big Data. As in Module 4 on supervised learning, the main emphasis will be on the analysis of real high-dimensional data sets from various scientific fields, including genomics and biomedical imaging. The techniques discussed will be demonstrated in R.

This course assumes some previous exposure to linear regression and statistical hypothesis testing, as well as some familiarity with R or another programming language.
