S. Singh et al., FUZZY NEURAL COMPUTING OF COFFEE AND TAINTED-WATER DATA FROM AN ELECTRONIC NOSE, Sensors and actuators. B, Chemical, 30(3), 1996, pp. 185-190
In this paper we compare the ability of a fuzzy neural network and a c
ommon back-propagation network to classify odour samples that were obt
ained by an electronic nose employing semiconducting oxide conductomet
ric gas sensors. Two different sample sets have been analysed: first,
the aroma of three blends of commercial coffee, and secondly, the head
space of six different tainted-water samples. The two experimental dat
a sets provide an excellent opportunity to test the ability of a fuzzy
neural network due to the high level of sensor variability often expe
rienced with this type of sensor. Results are presented on the applica
tion of three-layer fuzzy neural networks to electronic nose data. The
y demonstrate a considerable improvement in performance compared to a
common back-propagation network.
