Ensemble Selection
PhD Candidate

In machine learning, ensemble techniques nearly always outperform single-model techniques. Traditionally, ensembles have been constructed with the same base learner. Recently, however, Caruana et al (2004) developed and studied an ensemble technique (Ensemble Selection) that uses a wide variety of different base learners, and constructs the ensemble through greedy forward stepwise selection. Ensemble Selection attains state-of-the-art performance on a variety of problems, and can optimize to any easily computable performance metric. Some disadvantages of Ensemble Selection (e.g. the size of the resulting ensemble) can be partially overcome.

BACTAC, the Beverage And Chips Tuesday Afternoon Colloquium, is a weekly forum run by graduate students. The goal is provide an informal setting in which anyone can (basically) present anything. In the past, we have had practice talks for conferences and job interviews, research reports, juggle lessons (!), student representative reports, internship discussions, an introduction to ergonomics, and "pay attention to this when you are going to look for job" discussions.

BACTAC is meant to be an informal and social event to promote the interaction among graduate students. BACTAC is typically held every Tuesday, at 3:30pm, in room ECOT 831. Free munchies and drinks are provided.

Please email Caleb Phillips for more information or if you want to be a speaker.
