Conjoint analysis for quantification of relative importance of various factors affecting BPANN classification of urban environment
Pathak, Virendra & Dikshit, Onkar (2006) Conjoint analysis for quantification of relative importance of various factors affecting BPANN classification of urban environment. International Journal of Remote Sensing, 27(21), pp. 4769-4789.
This paper is an attempt to suggest an approach for eliminating the lengthy process of selecting various factors while using Backpropagation artificial neural network (BPANN) and to quantify the relative importance of the factors affecting classification results. A novel approach called conjoint analysis has been used here. The paper also presents the classification results of an Indian urban environment using two BPANN approaches and compares them with conventional Gaussian Maximum Likelihood (GML) classification approach. The study showed that conjoint analysis can be successfully used to select various parameters of BPANN prior to carrying out the classifications using any of the BPANN approach. Factors like size of training samples and first hidden layer come out as some of the most important factors while the second hidden layer has the least affect on classification accuracy. Resilient backpropagation method of BPANN is the best and robust method for urban classification. Results also showed that classification obtained using BPANN approach were similar or numerically better than GML classification though the difference was not statistically significantly different.
