How may I help you?

We are interested in providing automated services via natural spoken dialog systems. By natural, we mean that the machine understands and acts upon what people actually say, in contrast to what one would like them to say. There are many issues that arise when such systems are targeted for large populations of non-expert users. In this paper, we focus on the task of automatically routing telepho...

Does Good Mutation Help You Live Longer?

We study the dynamics of an age-structured population in which the life expectancy of an offspring may be mutated with respect to that of its parent. When advantageous mutation is favored, the average fitness of the population grows linearly with time t, while in the opposite case the average fitness is constant. For no mutational bias, the average fitness grows as t2 3. The average age of the ...

The Dizzy Patient: How You Can Help

Painstaking elucidation of a patient's symptoms is the key component of the diagnostic workup for dizziness and vertigo. A rational, straightforward, and cost-effective approach that uses minimal, selective diagnostic testing can get to the root of an individual's specific problem. Dizziness is a nonspecific complaint that can have different meanings in different patients, which makes careful a...
