An implementation of RADICAL, a method for independent component analysis (ICA). Assuming that we have an input matrix X, the goal is to find a square unmixing matrix W such that Y = W * X and the dimensions of Y are independent components. If the algorithm is running particularly slowly, try reducing the number of replicates. The input matrix to perform ICA on should be specified with the '--input_file (-i)' parameter. The output matrix Y may be saved with the '--output_ic_file (-o)' output parameter, and the output unmixing matrix W may be saved with the ’--output_unmixing_file (-u)' output parameter. For example, to perform ICA on the matrix 'X.csv' with 40 replicates, saving the independent components to 'ic.csv', the following command may be used: $ radical --input_file X.csv --replicates 40 --output_ic_file ic.csv
REQUIRED INPUT OPTIONS
--input_file (-i) [string] Input dataset for ICA.
OPTIONAL INPUT OPTIONS
--angles (-a) [int] Number of angles to consider in brute-force search during Radical2D. Default value 150. --help (-h) [bool] Default help info. --info [string] Get help on a specific module or option. Default value ''. --noise_std_dev (-n) [double] Standard deviation of Gaussian noise. Default value 0.175. --objective (-O) [bool] If set, an estimate of the final objective function is printed. --replicates (-r) [int] Number of Gaussian-perturbed replicates to use (per point) in Radical2D. Default value 30. --seed (-s) [int] Random seed. If 0, 'std::time(NULL)' is used. Default value 0. --sweeps (-S) [int] Number of sweeps; each sweep calls Radical2D once for each pair of dimensions. Default value 0. --verbose (-v) [bool] Display informational messages and the full list of parameters and timers at the end of execution. --version (-V) [bool] Display the version of mlpack.
OPTIONAL OUTPUT OPTIONS
--output_ic_file (-o) [string] Matrix to save independent components to. Default value ''. --output_unmixing_file (-u) [string] Matrix to save unmixing matrix to. Default value ''.
