Nonlinear Model-Based Method for Clustering Periodically Expressed Genes
Algorithm 2
The procedure for evaluating proposed clustering method.
(1) Repeat the following B times (where B is a preset integer number). | (a) Randomly divide the original dataset into two nonoverlapping sets, a | learning set , and a test set . | (b) Apply the evaluated method to the learning set to obtain a | partition. | (c) Construct a predictor (classifier) using the cluster labels from the | partition. | (d) Apply the predictor to the test set to get the predicted partition | . | (e) Apply the evaluated method to the test set to obtain a partition . | (f) Calculate the ARI of partitions and . | (2) Calculate the average ARI (AARI) over the B times as the measure index of the | proposed clustering method. | (3) For the various number of clusters, , repeat the procedure described in steps | (1) and (2) above to get AARI(), and then plot AARI() with respect to . |
