We propose a neural network approach for the problem of quantizer design for a distributed estimation system with communication constraints in the case where the global observation model is unknown and one must rely on a training set. Our method applies a variation of the Cyclic Generalized Lloyd Algorithm (CGLA) on every point of the training set and then uses a neural network for each quantizer to represent the training points and their associated codewords. The codeword of every training point is initialized using a previously proposed regression tree approach. Simulation results show that there is an improvement of the proposed approach over using regression trees only.
