## Theory Of Disagreement-Based Active Learning

Research Interests: My general interest in research applies to systems that can improve their performance through experience, a topic known as machine learning. I focus on the statistical analysis of Machine Learning. The essential questions I would like to answer are: “What can we learn from empirical observation/experimentation?” and “How much observation/experimentation is necessary and sufficient to learn it?” This over-the-board theme overlaps with several academic disciplines, including statistical learning theory, artificial intelligence, statistical inference, algorithmic and statistical information theories, probability theory, scientific philosophy, and cognitive theory.

The current version (v1.1) was updated on September 22, 2014. Some of the significant recent advances in active learning that have not yet been covered by the survey: [ZC14], [WHE-Y15], [HY15].

Prior to that, from 2009 to 2012, I was a visiting professor in the Department of Statistics at Carnegie Mellon University, also associated with the Department of Machine Learning. I received my Ph.D. in 2009 from the Department of Machine Learning at Carnegie Mellon University, which was co-advised by Eric Xing and Larry Wasserman. My final thesis focused on the theoretical foundations of active learning.

From 2002 to 2005, I studied computer science at the University of Illinois at Urbana-Champaign (UIUC), where I was a professor. Dan Roth and the cognitive computation group students worked on semi-supervised learning. Before that, I was studying computer science at Webster University in St. John`s. .
