The aim of this paper is to validate the new paradigm of evolutionary support vector machines (ESVMs) for binary classification also through an application to a real-world problem, i.e. the diagnosis of diabetes mellitus. ESVMs were developed through hybridization between the strong learning paradigm of support vector machines (SVMs) and the optimization power of evolutionary computation. Hybridization is achieved at the level of solving the constrained optimization problem within the SVMs, which is a difficult task to perform in its standard manner. ESVMs have been so far applied to the binary classification of two-dimensional points. In this paper, experiments are conducted on the benchmark problem concerning diabetes of the UCI repository of machinelearning data sets. Obtained results proved the correctness and promise of the new hybridized learning technique and demonstrated its ability to solve any case of binary standard classification
We apply the multiple optimizers with the learning- distributions to continuous decisions in a simulation model as integral decision-making components. In this machinelearning technique, the optimizers are given perf...

Integration of machinelearning methods into knowledge-based systems requires greater control over the application of the learning methods. Recent research in machinelearning has shown that isolated and unconstrained application of learning methods can eventually degrade performance. This paper presents an approach called performance-driven knowledge transformation for controlling the application of learning methods. The primary guidance for the control is performance of the knowledge base. The approach is implemented in the PEAK system. Two experiments with PEAK illustrate how the knowledge base is transformed using different learning methods to maintain performance goals. Results demonstrate the ability of performance-driven knowledge transformation to control the application of learning methods and maintain knowledge base performance.
