Comparative analysis of regression and ANN models for predicting drape coefficient of handloom fabrics

摘要

This paper reports a comparative analysis of two modeling methodologies for the prediction of drape coefficient of handloom cotton fabrics. Four primary fabric constructional parameters, namely ends per inch, picks per inch, warp count, weft count and fabric areal density (g/m~2) have been used as inputs for artificial neural network (ANN) and regression models. The prediction performance of both the models is found to be good as the correlation coefficient is higher than 0.9 and mean absolute error is less than 2.5%. However, ANN models are better than the regression models both in terms of correlation coefficient and mean absolute error. The importance of fabric parameters on drape coefficient has also been analysed by the developed ANN and regression models. The ranking of fabric parameters given by ANN and regression models are found to be in good agreement.
