Evaluating the algorithm's discriminative abilities. Using simulations and spectral clustering as described in the methods, algorithm performance is summarized by recall (A), precision (B) and F1 scores (C) as a function of increasing k. Each bar represents an average of 20 simulations, and for each value of k the same data and cluster assignments were used to find the shown recall, precision, and F1 score. The dark gray portions of each bar are the results if cluster assignments were randomly guessed. For these simulations the organism used was S. cerevisiae, and the information source was the Gene Ontology. Standard error bars are included.
