1. A computer system for generating gene regulatory models, comprising: at least one processing unit; memory operably associated with the at least one processing unit; and a regulatory modeling system storable in memory and executable by the at least one processing unit, the regulatory modeling system comprising: a data selection system that clusters gene expression data into a set of clusters and identifies a subset of the gene expression data from within the set of clusters; a relational fuzzy modeling system that builds a relational fuzzy model using the subset, wherein the relational fuzzy model is configured to generate gene regulatory models, wherein the relational fuzzy modeling system builds the relational fuzzy model from input and output data identified from the subset without using rules based on domain knowledge, wherein the relational fuzzy model comprises a relational array that maps all possible relationships between the input and output data and for each possible relationship provides an indication of the strength in the relationship between the input and output data; and an output unit that generates at least one display of the gene regulatory models.
