rofi(MLinput, source_alg_pairs, nn = 1, f_prob = 0.1, nu = 1/100,
  max_iter = 2 * sum(attr(MLinput, "data_info")$number_of_features),
  conv_check = (sum(attr(MLinput, "data_info")$number_of_features) + 1),
  epsilon = 0.01, after_conv_checks = 100)

Arguments

MLinput

an as.MLinput object which contains a single X data frame or a list of X data frames, a Y data frame and attributes

source_alg_pairs

a named vector of algorithms (one of "knn", "nb", "svm", or "rf") with names as the corresponding data source

nn

integer. The number of times to repeat the optimization in its entirety

f_prob

numeric greater than 0 and leq 1. The proportion of the full feature set to initialize the optimization routine

nu

numeric greater than 0 and leq 1. The scale value for feature acceptance criteria of a difference in AUC values

max_iter

int. Maximum number of iterations to allow in nn iterations

conv_check

int. Number of iterations at which to perform a convergence check. Typically set to the total number of features

epsilon

numeric greater than 0 and leq 1. AUC convergence threshold, typically small (< 0.1).

after_conv_checks

int. After the initial convergence check, the Interval of iterations at which to perform a convergence check
