Speaker: Derren Barken Topic: Introduction to Classification Models (e.g. diagnostic tests) and Machine Learning in R The San Diego R Users Group will be meeting on Monday, May 24, from 6:30-8:30 PM at Sequenom. (Prior RSVP requested; please see below). Our next meeting will be about using R for classification problems, such as diagnostic and prognostic medical tests. This topic will be covered over two talks. In our May meeting, we will demonstrate in detail how to use R with several popular, relatively simple algorithms / packages, including logistic regression and decision trees. We will then discuss some issues which arise in real-world classifier design, such as validation methodology, variable selection, variable preprocessing, and handling missing data. In a future meeting (to be scheduled later), we will cover more advanced classification techniques, such as neural networks, support vector machines, random forests, boosting, and ensemble methods. Derren Barken is a Bioinformatics Scientist with Prometheus Laboratories. He completed his Ph.D. in Bioinformatics at UCSD in 2007; prior to graduate school, he worked as a programmer in Silicon Valley and Boston.
