Polynomial Radial Base Function: A New Local Similarity Measure

摘要

This paper studies the local similarity measure function. First, we propose polynomial radial base function (PRBF) as a local similarity measure. Then we compare the properties between Gaussian radial base function (GRBF) and PRBF, and show PRBF not only is similar to GRBF but also is of a faster computational rapidity. PRBF is a good substitute for GRBF when high computational rapidity is demanded.
