A modified version of Boosted Mixture of
Experts (BME) is presented in this paper. While previous
related works, namely BME, attempt to improve the performance
by incorporating complementary features of a
hybrid combining framework, they have some drawback.
Analyzing the problems of previous approaches has suggested
several modifications that have led us to propose a
new method called Boost-wise Pre-loaded Mixture of
Experts (BPME). We present a modification in pre-loading
(initialization) procedure of ME, which addresses previous
problems and overcomes them by employing a two-stage
pre-loading procedure. In this approach, both the error and
confidence measures are used as the difficulty criteria in
boost-wise partitioning of problem space.
