       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.
