N2 - This paper presents a hybrid auto-associative neural networks that combines the functionality of radial basis functions, multilayer perceprons and principal component analysis. This hybrid network is developed and its performance in conjunction with the GA is compared to that of an ordinary AANN. A PCA and neural network missing data estimation system is also developed and compared to the other two systems. A description of the methodology is presented followed by the experimental implementation using HIV data from the department of Health. Accuracies of up to 95% are achieved on imputation of some of the variables.
