It is not yet possible to predict an individual's outcome from percutaneous transluminal coronary angioplasty or alternative/adjunctive coronary interventional techniques. The purpose of the INTERVENT project is to redefine complications associated with coronary interventions, to set up a prognostic computer model to predict individual outcome and to compare the results to those of conventional...

Current cancer classifications using morphological criteria produce heterogeneous classes with variable prognosis and clinical course. By measuring gene expression for thousands of genes in a single hybridization experiment, microarrays have the potential to contribute to more effective classifications based on molecular information. This gives hope to improve both prognosis and treatment. Stat...

Decision-tree algorithms are known to be unstable: small variations in the training set can result in different trees and different predictions for the same validation examples. Both accuracy and stability can be improved by learning multiple models from bootstrap samples of training data, but the “meta-learner” approach makes the extracted knowledge hardly interpretable. In the following paper...

The package RTN is designed for reconstruction and analysis of transcriptional networks (TN) using mutual information [1]. It is implemented by S4 classes in R [2] and extends several methods previously validated for assessing transcriptional regulatory units, or regulons (e.g. MRA [3], GSEA [4], synergy and shadow [5]). The package computes mutual information (MI) between annotated transcripti...
