public class CombinatorPipeline
extends Combinator

A row combinator, which is just a composition of multiple smaller row combinators. It takes the initial approximation of the combination matrix, that is created as by-product in the second step, and sequentially applies all sub-combinators to it. Particularly useful to append strictly improving algorithms (like Iter) to some other combinator, that might generate a better initial guess.

Description copied from class: Combinator

Describes a row of the original matrix as combination of basis rows from the basis matrix.

Specified by:

combineRow in class Combinator

Parameters:

row - a row from the original matrix

previousCombination - approximation, already obtained by previous steps

basis - the basis matrix (with basis patterns as rows)

onesWeight - relative weight of 1 -> 0 errors

Returns:

single row, that has a 0 or 1 entry for each basis row
