A method and computer program with program code means, and computer program product for determining a structure contained in data using separable graphical models
The invention relates to a detection of a graphical model structure into data for continuous variables. Here, a graphical model to describe the data is broken down into subgraphs. Using kernel density estimators subgraph densities are determined for the partial graphs. Using the subgraph densities, and a method of a cross-validation scheme, an evaluation function is determined which rated adding an edge to the model in terms of a description of the quality of a structure contained in the data by the model. Using the evaluation function those edges are determined, which are inserted into the model, and thus determines the graphical model structure.
