    Deep learning is just a rebranding of "neural networks". When neural nets became unpopular in the 90s and early 2000s, people talked about "multilayer networks" (dropping the "neur…

    >If you were to run almost any kind of reasonable attempt at analyzing and valuing Tesla based on what it should maybe be worth via comparables, you'd get a figure dramatically low…

    It won't be used for the rocket but for the Mars transport spaceship.

    But cost is also at issue. For cargo, it might make sense to take on 0.5-1.0% risk versus the massive investments necessary for the development of a space elevator. And when we're …

    Probably the biggest barrier to space elevators is exactly what SpaceX and Blue Origin are doing - safe, reliable, and eventually (relatively) inexpensive rockets will make the lar…

    >Space-X can't make and launch Falcon boosters fast enough now. The bottleneck is not Falcon 9 production, at this point it's largely on the payload side. A faster turnaround would…

    >Not necessarily, often derivatives are analytically known in ML. The focus here is largely on deep neural networks. In this domain, the Hessian cannot be computed and SGD (with mi…

    While Matlab still probably comes ahead in image processing, surely in computer vision Python is on top? You mentioned academic research, isn't the majority of modern object recogn…
