abstract = "This paper describes performance of a neural network
and genetic programming (GP) in identifying the state
of contact in a distributive tactile sensing system.
The chosen architecture for the neural network is a
multilayer perceptron while that for the genetic
programming is a structured representation on genetic
algorithms for non-linear function fitting
(STROGANOFF). The tactile system comprises a small
matrix of sensors for detecting deformation of a
tactile surface. The determination of contact state is
completed using both simulated and experimental inputs.
Because the system relies on few sensing positions
hence a robust interpreting algorithm plays a vital
role. The study involves the identification of the
position of a pointed load for a range between 200-600
g which can be applied across the surface. The
performance in determining the position is described in
the form of absolute deviation from the actual applied
position. The simulation result indicates that the
multilayer perceptron is the best inference technique
while the GP-based mapping model produces a better
result in an experiment with a high load. The
difference between the simulation and the experiment is
the result of an inability of the simulation model at
capturing true plate deflection characteristics.",
