ELECTRONIC DEVICE AND CONTROL METHOD THEREOF

Disclosed is an electronic device. The present electronic device includes: a memory; and a processor which quantizes a neural network, trained on the basis of deep learning, to generate a quantized neural network, and stores the quantized neural network in the memory, wherein the processor quantizes, in preset first bit units, trained connection strengths between neurons of the trained neural network, inverse-quantizes the quantized connection strengths in preset second bit units, retrains the inverse-quantized connection strengths, and quantizes the retrained connection strengths in the preset first bit units.
