Machine Learning Seminars

Title: Causality
Speaker: Thomas Richardon, University of Washington
When: Tuesday, February 28, 2012 - 12:30
Location: EEB 037

As these talks are intended as overviews, time permitting, I plan to give two mini-tutorials: The first will be on the idea of counterfactuals/potential outcomes. Basically answering the question: how does data obtained from a simple randomized experiment differ from that obtained from an observational study, and how does that weaken inferences that can be obtained. The second will require assume a little bit of background on Bayesian networks and will answer the question: if we obtain data from a subset of the variables in a causal Bayesian network, which causal effects are identified and how can they be computed efficiently.

Title: Submodular Functions and Active Learning
Speaker: Andrew Guillory, University of Washington
When: Tuesday, January 10, 2012 - 12:30
Location: EEB 037

This tutorial presents a brief survey of active learning, submodular functions, and the interesting algorithms and analyses at their intersection. Minimal background knowledge is assumed, and emphasis is placed on open problems and gaps between theory and practice.

Title: Machine Learning and Big Data Analysis
Speaker: Alice Zheng
When: Tuesday, November 29, 2011 - 12:30
Location: CSE 305

Our world is becoming more data driven. With the spread of ubiquitous sensors, network connectivity, and massive storage capabilities, we are able to collect more and more data. But our computation and analysis capabilities have not increased at a comparable rate. Computer scientists are facing looming questions such as "How do we deal with the massive amounts of data we are collecting? How can we extract value out of data?" A sub-question relevant to machine learning researchers is "what role will machine learning and data mining play?" Through a survey of current sources of Big Data and analysis workflow patterns, this talk aims to shed light on the latter question.

 

Title: Entire Relaxation Path for Maximum Entropy Models
Speaker: Yoram Singer
When: Tuesday, November 22, 2011 - 12:30
Location: CSE 305

We describe a relaxed and generalized notion of maximum entropy problems for multinomial distributions. By introducing a simple re-parametrization we are able to derive an efficient homotopy tracking scheme for the entire relaxation path using linear space and quadratic time. We also show that the Legendre dual of the relaxed maximum entropy problem is the task of finding the maximum likelihood estimator for an exponential distribution with L1 regularization. Hence, our solution can be used for problems such as language modeling with sparse parameter representation.
