# mlpack\_radical(1)

radical

## 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.
