When clustering a dataset, the right number k of clusters to use is often not obvious, and choosing k automatically is a hard algorithmic problem. In this paper we present an impr...
We derive the limiting form of the eigenvalue spectrum for sample covariance matrices produced from non-isotropic data. For the analysis of standard PCA we study the case where th...
While Internet telephony aims to provide services at least equal to traditional telephony, the architecture of Internet telephony is sufficiently different to make it necessary to ...
In this paper, we follow a new path to arrive at the idea of a COMA — a Cache Only Memory Architecture. We show how the evolution of another architecture (ADARC) leads quite nat...
This paper proposes a new planning architecture for agents operating in uncertain and dynamic environments. Decisiontheoretic planning has been recognized as a useful tool for rea...
