A model for <italic>approximate testing</italic> of concepts, which relates to the PAC model of learning, has been developed. In this model an approximate testing algorithm produces a finite set ofâ€¦ (More)

Testing plays an integral part in many areas of computer science. In relation to computational learning theory, testing can be viewed as an inverse process to learning. Testing algorithms create aâ€¦ (More)

We examine the complexity of testing di erent program constructs. We do this by de ning a measure of testing complexity known as VCP-dimension, which is similar to the Vapnik-Chervonenkis dimension,â€¦ (More)

We consider the problem of localizing a robot in a known environment modeled by a simple polygon P . We assume that the robot has a map of P but is placed at an unknown location inside P . From itsâ€¦ (More)

User modeling can be used in information filtering and retrieval systems to improve the representation of a userâ€™s information needs. User models can be constructed by hand, or learned automaticallyâ€¦ (More)
