This adversely limits the design of a neural network-based classifier embedded in the hearing aid. Aiming at helping the processor achieve accurate enough results and in the effort of reducing the number of instructions per second this paper focuses on exploring 1 the most appropriate quantization scheme and 2 the most adequate approximations for the activation function. The experimental work proves that the quantized approximated neural network-based classifier achieves the same efficiency as that reached by exact networks without these approximations but this is the crucial point with the added advantage of extremely reducing the computational cost on the digital signal processor.
