As our interest is the discovery of TRNs as defined above, the question is how one can use the gene-gene similarity scores and the preliminary TRN to score gene/TF interactions. For a system of Ngene genes, there are Ngene × (Ngene - 1)/2 gene-gene pairs. In order to find the score for gene A and TF B, we first seek all genes regulated by TF B in the preliminary TRN. Then we calculate the gene-gene similarity score for the gene of interest with each gene regulated by TF B. We assign the maximum of these scores to the gene A/TF B interaction. Although this appears to be a rough estimation of the gene-TF score, our computational experiments with gene-gene similarity based on gene ontology and phylogeny have shown that this score clearly distinguishes the probability distributions of the training and random sets of gene/TF interactions.","divisions":[{"label":"title","span":{"begin":0,"end":39}}],"tracks":[]}
