FPGA Implementation of a Recurrent Neural Fuzzy Network with On-Chip Learning for Prediction and Identification Applications
並列摘要
In this paper, a hardware implementation of a recurrent neural fuzzy network (RNFN) used for identification and prediction is proposed. A recurrent network is embedded in the RNFN by adding feedback connections in the second layer, where the feedback units act as memory elements. Although the back propagation (BP) learning algorithm is widely used in the RNFN, BP is too complicated to be implemented using hardware. However, we use the simultaneous perturbation method as a learning scheme for hardware implementation to overcome the above-mentioned problems. The hardware implementation of the RNFN uses random access memory (RAM), which stores all the parameters of a network. This design method reduces the number of logic gates used. The major findings of the experiment show that field programmable gate arrays (FPGA) implementation of the RNFN retains good performance in identification and prediction problems.
