OBJECTIVES

Machine learning refers to the use of computers to perform automated statistical algorithms to solve certain problems or fulfill certain objectives. Machine learning can be viewed as an intersection between statistics and computer science. What distinguishes these problems from routine problems that can be addressed with manual techniques are large numbers of numbers of variables or elements. In biomedical research, machine learning is most commonly used for the objectives of prediction (predicting either a unknown current state or a future condition from a variety of currently available data elements), pattern recognition (also known as cluster analysis, where the goal is to group a set of persons or objects in such a way that objects in the same group are more similar to each other than to persons/objects in other groups), and data reduction (also known as dimensionality reduction where the goal is to summarize many data elements into fewer elements while retaining much of the contain ed information). Through use of the R software environment, this course will provide an introduction to use of machine learning to solve problems of prediction, pattern recognition, and data reduction in the various fields related to biomedical research (e.g., biological sciences, imaging sciences, epidemiologic research; and clinical research). The specific objectives include learning how to:

  • Understand the rationale and mechanics of a range of machine learning techniques (e.g., regression trees and random forests, support vector machines, neural networks and deep learning, penalized regression techniques, clustering, and principal components analysis) to address problems of prediction, pattern recognition, and/or data reduction;
  • Implement a variety of machine learning techniques in R software; and
  • Apply the knowledge and techniques to the completion of a real-world biomedical project in the realm of prediction, pattern recognition, and/or data reduction.
