Should Deep Learning use Complex Numbers? – Intuition Machine – Medium

Is it not odd to anyone that Deep Learning uses only real numbers? Or perhaps, it would be even odder if Deep Learning uses complex numbers (note: the kind with imaginary numbers). One viable argument is that it is highly unlikely that the brain uses complex numbers in its computation. However, you can make the argument also that the brain doesn't perform matrix multiplication or perform chain rule differentiation. Besides, Artificial Neural Networks (ANN) have a cartoonish model of actual neurons.
