>> “I probably won’t put a lot of time into machine learning efforts,” he said, “because although machines can learn, they can’t yet explain to us what they have learned.” So, as usual with the use of deep learning in the sciences, we had a lot of data that we couldn't understand, then we built a model that represents the data, and now we have a model that we can't understand. I continue to be reminded of that early Pinky and the Brain episode: The Brain plans to use a "growing ray" (originally a "shrinking ray") to grow Pinky into super-size while dressed up as Gollyzilla, while Brain would turn himself gigantic and stop him, using the name Brainodo, in exchange for world domination. However, the real Gollyzilla emerges from the ocean and starts to rampage through the city, making Brain think that the dinosaur is Pinky. The episode ends with the ray going out of control and making everything on Earth grow, including the Earth itself, to the point that Pinky, the Brain, and even Gollyzilla are mouse-sized by comparison again. https://en.wikipedia.org/wiki/List_of_Pinky_and_the_Brain_episodes#Season_1_(1995%E2%80%9396) https://en.wikipedia.org/wiki/List_of_Pinky_and_the_Brain_ep...
