In part three of the 27.64 episodes long mini-series on artificial intelligences, machine and deep learning and other hipster topics around machines trying to imitate humans (marketing made us do these :-), our two heroes discuss domain-specific frameworks on top of (more generic) infrastructure like TensorFlow or PyTorch. As usual, all will be revealed and no details be spared (apart from a very few) including how to tell animals apart from humans (a tricky feat as any journalist can tell you who's ever faced a stampeding horde of angry politicians!).
