welcome.
I'm a Computer Science Ph. D. student at Northwestern University. I received my B.S. in Computer Science and M.S. in Computer Science from Washington University in St. Louis, in 2003 and 2005, respectively.
I research with the Qualitative Reasoning Group, actively investigating several of my interests within the field of Artificial Intellgience.
Learning Causal ModelsMany existing theories of inferring causality incorporate statistics alone; I am investigating using qualitative modeling to represent the actual mechanisms of change and permit deeper domain theories. Conceptual ChangeWhen people learn new theories or they realize their current conceptualization is at odds with reality, they have the ability to change their concepts over time and use new explanations to make sense of past and future experiences. I am investigating achieving the same task with qualitative reasoning systems. Natural Language ProcessingHow best can computers disambiguate and extract the semantic content from our natural (human) language? |
