fANOVA

fANOVA is a tool for assessing the importance of an algorithm’s hyperparameters. It takes as input performance data gathered with different hyperparameter settings of the algorithm, fits a random forest to capture the relationship between hyperparameters and performance, and then applies functional ANOVA to assess how important each of the hyperparameters and each low-order interaction of hyperparameters is to performance.

Software

The fANOVA package can be obtained on our github page (external link). Documentation is available on github.io (external link).
