An implementation of RADICAL, a method for independentcomponent analysis (ICA). Assuming that we have an input matrix X, thegoal 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 runningparticularly slowly, try reducing the number of replicates.


--input_file (-i) [string]
Input dataset filename for ICA.


--angles (-a) [int]
Number of angles to consider in brute-force search during Radical2D. Default value 150.
--help (-h)
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)
If set, an estimate of the final objective function is printed.
--output_ic (-o) [string]
File to save independent components to. Default value 'output_ic.csv'.
--output_unmixing (-u) [string]
File to save unmixing matrix to. Default value 'output_unmixing.csv'.
--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)
Display informational messages and the full list of parameters and timers at the end of execution.
--version (-V)
Display the version of mlpack.
