We consider the problem of modeling network interactions and identifying latent groups of network nodes. This problem is challenging due to the facts i) that the network nodes are...
Relational database systems represent the current standard technology for implementing database applications. Now that the object-oriented paradigm becomes more and more mature in...
We propose a multi-dimensional language called nD-SQL with the following features: (i) nD-SQL supports queries that interoperate amongst multiple relational sources with heterogen...
Abstract. Normal mixture models are often used to cluster continuous data. However, conventional approaches for fitting these models will have problems in producing nonsingular es...
In this paper we discuss verification and validation of simulation models. The different approaches to deciding model validity are described, two different paradigms that relate v...
