Abstract :
The authors present the effects of employing limited precision arithmetic on radial basis function networks (RBF). A statistical formula is first derived to obtain an analytical expression for the error so that it can be used for hand-calculations. A speech processing example is chosen to compare the theoretical results with its simulation counterparts. The results indicate that limited precision implementation achieves as nearly good recognition results as its floating counterpart
