The design of microwave and millimeter-wave circuits and the increasing integration of hybrid and monolithic circuits has reinforced the need of accurate large and small-signal device models to...
A new EM-based training algorithm for RBF networks (2003)
Marcelino Lázaro, Ignacio Santamaría, Carlos Pantaleón
In this paper, we propose a new Expectation–Maximization (EM) algorithm which speeds up the training of feedforward networks with local activation functions such as the Radial Basis Function (RBF)...
