Dietterich Department of Computer Science Oregon State University Corvallis, OR 97331 1 Introduction Machine Learning is the study of methods for programming computers to learn. Computers are applied to a wide range of tasks, and for most of these it is relatively easy for programmers to design and implement the

5a_Uncertainty.dvi COMP9414 Uncertainty 1 Reasoning with Uncertainty � An agent can not always ascertain the truth of all propositions, so may not only have “flat out” beliefs (P or ¬P) � Some environments themselves generate uncertainty for the agent, due to unpredictability or nondeterminism, so propositions inadequately model those environments � Rational decisions for an

Clearly explaining a rationale for a classification decision to an end-user can be as important as the decision itself. Existing
the combination of flit buffer flow control methods and latency insensitive protocols is an effective solution for networks on chip noc since they both rely on backpressure the two techniques are easy to combine while offering complementary advantages low complexity of router design and the ability to cope with long communication channels via automatic wire
