Sincerely, DREAM4 Conference and Challenge Organizers: Gustavo Stolovitzky (chair), IBM Research Robert J Prill, IBM Research Andrea Califano, Columbia University DREAM4 is part of a project we call the DREAM (Dialogue for Reverse Engineering Assessments and Methods) project. Its main objective is to catalyze the interaction between experiment and theory in the area of cellular network inference. The fundamental question for DREAM is simple: How can researchers assess how well they are describing the networks of interacting molecules that underlie biological systems, and how well can they predict the results of a biological experiment? The answer is not so simple. Researchers have used a variety of algorithms to deduce the structure of very different biological and artificial networks, and evaluated their success using various metrics. What is still needed, and what DREAM aims to achieve, is a fair comparison of the strengths and weaknesses of the methods and a clear sense of the reliability of the network models they produce. -- Tom Michoel <http://www.psb.ugent.be/~tomic/>
