mlpack_radical — radical


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


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.

Required Options

--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.
