Stability evaluation of Neural and statistical Classifiers based on Modified Semi - bounded Plug - in Algorithm

چکیده

This paper illustrates a new criterion for evaluating neural networks stability compared to the Bayesian classifier. The stability comparison is performed by the error rate probability densities estimation using the modified semi-bounded Plug-in algorithm. We attempt, in this work, to demonstrate that the Bayesian approach for neural networks improves the performance and stability degree of the classical neural classifiers. Keywords—Bayesian neural networks, error rate density, modified semi-bounded Plug-in algorithm, stability, theoretical error rates.

The Use of the Modified Semi - bounded Plug - in Algorithm to Compare Neural and Bayesian Classifiers Stability

Despite of the widespread use of the neural networks in the industrial applications, their mathematical formulation remains difficult to analyze. This explains a limited amount of work that formally models their classification volatility. Referring to the statistical point of view, we attempt in this work to evaluate the classical and Bayesian neural networks stability degree compared to the st...
