1. A computer-implemented method for generating gene regulatory models, comprising: clustering gene expression data to generate a set of clusters; identifying a subset of the gene expression data from within the set of clusters; building a relational fuzzy model using the subset, wherein the building of the relational fuzzy model comprises using input and output data identified from the subset to build the relational fuzzy model 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; testing the relational fuzzy model on the gene expression data in the set of clusters; using the relational fuzzy model to generate gene regulatory models; and outputting at least one display of the gene regulatory models; wherein each of said method steps is performed on a computer.
