An efficient method for tuning handwriting parameters

Abstract

Many problems in recognition involve making linear combinations of results from various experts. Computing the coefficients can be expensive because a single test run can take many minutes, hours, or even days, and many values need to be evaluated to find an optimum. This paper describes an algorithm that can make a good approximation to the optimum value for a parameter in a single pass over the tuning data and also outlines methods for tuning several parameters at once.
