The notion of an intelligent agent in AI is too coarse and in need of refinement. We suggest that the space of AI agents can be subdivided into classes, where each class is defined by an associated degree of control.
AI Magazine, 2018

It is easy to see that social robots will need the ability to detect and evaluate deceptive speech; otherwise they will be vulnerable to manipulation by malevolent humans. More surprisingly, we argue that effective social robots must also be able to produce deceptive speech.
Robot Ethics 2.0, 2017

We describe an attention-centric cognitive system called ARCADIA that demonstrates the orienting, filtering, and resource-skewing functions commonly attributed to attentional mechanisms.
38th CogSci Conference, 2016

We pose a novel research problem for machine learning that involves constructing a process model from continuous data.
Machine Learning, 2008

We developed a simple regular expression algorithm called NegEx that implements several phrases indicating negation, filters out sentences containing phrases that falsely appear to be negation phrases, and limits the scope of the negation phrases.
Journal of Biomedical Informatics, 2001

If you’re in the market for an academic job, chances are that you’ll have to submit a research statement of some sort. These critters offer you the chance to distill your life’s work and dreams into a short essay that can only hurt your chances of employment. Since you probably just finished your thesis where length is a virtue writing this statement can be daunting. While examples of research papers abound, there are relatively few research statements on the web.
