4th IEEE International Symposium on Electronic Design, Test and Applications (delta 2008)
A Spiking Neural Network for Gas Discrimination Using a Tin Oxide Sensor Array
January 23-January 25
ISBN: 978-0-7695-3110-6
We propose a bio-inspired signal processing method for odor discrimination. A spiking neural network is trained with a supervised learning rule so as to classify the analog outputs from a monolithic 4x4 tin oxide gas sensor array implemented in our in-house 5 micrometers process. This scheme has been sucessfully tested on a discrimination task between 4 gases (hydrogen, ethanol, carbon monoxide, methane). Performance compares favorably to the one obtained with a common statistical classifier. Moreover, the simplicity of our method makes it well suited for building dedicated hardware for processing data from gas sensor arrays.
