The optimisation of a parallel distributed detection system with N sensors always leads to a set of 2N + N non linear equations, which is only solved in particular cases, assuming statistical independence of the local observations and for systems constituted by very few sensors. Usually, the number of equations to solve increases very quickly with the number of sensors. The computations become unfeasible. In this paper, a selection procedure of sensors relevant for the decision process based on the use of Shannon's conditional entropy is developed. Then, these systems are optimized via en entropy based method. This one determines the local thresholds and constructs a decision tree which minimises the decision error probability. This a...
