Breaking Down Leon Gatys’ Neural Style Transfer in PyTorch

Neural Style Transfer performed on an image of a cat.

In 2015 Leon Gatys et al. proposed a method for Neural Style Transfer in their paper “A Neural Algorithm of Artistic Style” (arXiv:1508.06576v2). I was always fascinated by the fact that neural network models are capable of something like style transfer and at the time the results seemed like magic to me. In this short article, I want to dwell into the implementation of the original Neural…
