In this paper, we present meta-learning evolutionaryarti!cial neural network (MLEANN), an automatic computational framework for the adaptive optimization of arti!cial neural networks (ANNs) wherein the neural network architecture, activation function, connection weights; learning algorithm and its parameters are adapted according to the problem. We explored the performance of MLEANN and conventionallydesigned ANNs for function approximation problems. To evalu- ate the comparative performance, we used three di5erent well-known chaotic time series. We also present the state-of-the-art popular neural network learning algorithms and some experimentation results related to convergence speed and generalization performance. We explored the perfor- mance of backpropagation algorithm; conjugate gradient algorithm, quasi-Newton algorithm and Levenberg-Marquardt algorithm for the three chaotic time series. Performances of the di5erent learning algorithms were evaluated when the activation functions and architecture were changed. We further present the theoretical background, algorithm, design strategyand further demonstrate how e5ective and inevitable is the proposed MLEANN framework to design a neural network, which is smaller, faster and with a better generalization performance. c
