## Detailed Description

Option object for the pLSA algorithm.

## Constructor & Destructor Documentation

PLSAOptions | ( |  | ) |

Initialize all options with default values.

## Member Function Documentation

PLSAOptions& maximumNumberOfIterations | ( | unsigned int | n | ) |

Maximum number of iterations which is performed by the pLSA algorithm.

default: 50

PLSAOptions& minimumRelativeGain | ( | double | g | ) |

Minimum relative gain which is required for the algorithm to continue the iterations.

default: 1e-4

PLSAOptions& normalizedComponentWeights | ( | bool | v = `true` | ) |

Normalize the entries of the zv result array.

If true, the columns of zv sum to one. Otherwise, they have the same column sum as the original feature matrix.

default: true
