Tetrad: Machine Learning and Graphical Causal Models
Richard Scheines, Carnegie Mellon University

8:30 AM - 4:30 PM

Abstract: Tetrad (free software) contains over 20 algorithms for searching for a variety of model classes, e.g., path analytic models, Bayes nets, factor analytic and structural equation models, general latent variable models of conditional independence structures, and Markov blankets. In this workshop, we will briefly introduce graphical causal models, show how to build, simulate data from, and estimate such models in Tetrad, explain model search, teach how to use a variety of the search algorithms in Tetrad on real and simulated data including fMRI data to find causal relations between brain regions.
Who Should Attend: Researchers in the social and behavioral sciences as well as in the life sciences could benefit from this class.
Note: wireless access will be available at the venue, participants are encouraged to bring laptops or tablets.
Speaker Biographies:
Richard Scheines is the Head of Philosophy, with joint appointments in Machine Learning and Human-Computer Interaction at Carnegie Mellon University. Along with Peter Spirtes and Clark Glymour, Scheines has published several books and dozens of articles on graphical causal models over the last 20 years. He has used model search in Tetrad to model the effect of lead on IQ, the effect of online courseware on student learning, and several other social scientific questions. Scheines has also served on several IOM committees reviewing the statistical evidence for causation in veteran's disability claims and for the effect of food marketing on childhood obesity.
Joseph Ramsey is a PhD in Philosophy of Science from the University of California, San Diego, and is currently the Director of Research Computing at Carnegie Mellon's Lab for Symbolic and Educational Computing, as well as the chief developer of the Tetrad programs. Ramsey has done extensive algorithm development and applied work in causal modeling, including spectral identification of carbonate content, and most recently the identification of causal pathways in brain processing from fMRI data, work that is recently published in NeuroImage.
