       mlpack_radical - radical

SYNOPSIS

        mlpack_radical -i unknown [-a int] [-n double] [-O bool] [-r int] [-s int] [-S int] [-V bool] [-o unknown] [-u unknown] [-h -v]

DESCRIPTION

       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:

       $ mlpack_radical --input_file X.csv --replicates 40 --output_ic_file ic.csv

REQUIRED INPUT OPTIONS

       --input_file (-i) [unknown]
              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]
              Print help on a specific 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) [unknown]
              Matrix to save independent components to.

       --output_unmixing_file (-u) [unknown]
              Matrix to save unmixing matrix to.
