NAME
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.
