Abstract

It has been generally acknowledged that relevance feedback in image retrieval can be considered as a two-class learning and classification process. The classifier used is essential to the performance of relevance feedback. In this paper, a RBF neural network is employed during the relevance feedback process. The architecture of the RBF network is automatically determined by the constructive learning algorithm (CLA). The weights in the output layer of the network are learned by Least-mean-square method. Experiment results on 10,000 heterogeneous images demonstrate the proposed CLA-based RBF network can achieve comparable performance with support vector machines and support vector learning based RBF during the relevance feedback process. Furthermore, a practical advantage of the CLA-based RBF network is that the width of Gaussian kernel does not need to manually set while for SVM it need to be predefined according to experience.
