  1. Re:Online Go tournaments? on Facebook's Open-Source Go Bot Can Now Beat Professional Players (techcrunch.com) · · Score: 3, Interesting

    People are already using LeelaZero (the #3 ranked in gobot competition and capable of beating 9d professionals) to cheat, but when a human plays drastically better than their rating, the cheating is pretty obvious.

  2. So can LeelaZero on Facebook's Open-Source Go Bot Can Now Beat Professional Players (techcrunch.com) · · Score: 4, Informative

    LeelaZero - an open source go bot, has beat 9d professionals and other lower ranked professionals. It is also ranked #3 in the world in gobot competitions, and that was with using half or less of the hardware resources that many of hte competitors had (LeelaZero was using 4 1080 TI GPUs; the competitors had 10 1080 TI GPUs).

    It still hasn't reached the level of AlphaZero, but if you'd like to help it do so, you can contribute here.

    Note that they benchmarked against LeelaZero, but had it misconfigured - they gave their bot 80,000 playouts, and LeelaZero 50 seconds per move, but left a default where LeelaZero doesn't use all of its time. So often it was moving in 3 seconds. It might well be weaker than LeelaZero on similar hardware when LeelaZero is correctly configured.

    We actually have no idea if it is possible. We certainly can't do it with today's technology - but it may be that the connectome and other information (mylenation thickness and extent) preserved when freezing the brain - may be sufficient to do a digital simulation/upload 'in the future'.

    A connectome does seem adequate to simulate extremely simple nervous systems.

    The gain difference isn't necessarily artificially darkened. It is speculated it was tuned so that it wouldn't be blown out by headlights of oncoming traffic. Without high dynamic range cameras, you have tradeoffs for what lighting conditions your camera is adapted for.

    What reason did the Uber car have for going 38 in a 35 zone?

    I was doing 38 it a 45 (there is a photo online of the speed limit sign). The report of it being a 35 zone was a misreport/misspeak by the police representative.

    Microsoft has 124,000 employees, 25.8% that are women.

    So 31,992 women with 40 complaints a year. so .1% of female employees file a complaint each year. I suspect that is probably less than the industry norm.

    [quote]On the flip side, it's a good time to learn how to be a robot repair person. These things are going to break, frequently.[/quote]

    Training robots to repair robots will probably be quite easy. Usually it will be just swapping out a complete sub assembly. Then the subassembly will be shipped to a central repair location (if it is expensive enough to be worth repairing) where it can be run through advanced diagnostic and repair tools.

    There will never be a significant number of 'robot repair' jobs for humans.

    It isn't clear if the allegations are true. TFA says the accuser "walked back" some of his allegations, which is a euphemism for "admitted he was lying".

    After he wrote the letter he was hired as a 'consultant' for 4.5 million dollars, of which, it is paid out over time and he has thus far recieved 1 million (a significant percentage of the payment is due at the end of the contract). If he testifies that everything in the document is true, he will likely be fired and not get 3.5 million dollars, so he has 3.5 million reasons to say that the document isn't accurate.

    It isn't in GANs one model, the generative, tries to fool the other, classifier one, by giving it images itself has generated. There's no incremental task switching from easier problem domains to more difficult ones.

    I'm familiar with GANs - what it sounded like (and what they did) is add curriculum learning, but they also did it layerwise as is done with autoencoders, (Also they had some other interesting ideas, but that was the crucial bit). In this case the easy is the lower resolution images and the hard is the higher dimensional images.

    From their paper

    The idea of growing GANs progressively is related to curriculum GANs (Anonymous), where the idea is to attach multiple discriminators that operate on different spatial resolutions to a single generator, and furthermore adjust the balance between resolutions as a function of training time. That work in turn is motivated by Durugkar et al. (2016) who use one generator and multiple discriminators concurrently, and Ghosh et al. (2017) who do the opposite with multiple generators and one discriminator. In contrast to early work on adaptively growing networks, e.g., growing neural gas (Fritzke, 1995) and neuro evolution of augmenting topologies (Stanley & Miikkulainen, 2002) that grow networks greedily, we simply defer the introduction of pre-configured layers. In that sense our approach resembles layer-wise training of autoencoders (Bengio et al., 2007).

    I studied AI algorithms back in University a decade ago and they really haven't changed much from now till today. The biggest improvements have come from having faster computers, not more efficient or even effective algorithms.

    Actually a number of algorithmic improvements were needed to train deep networks, so it isn't just hardware, some major algorithmic improvements have occurred also. Also GAN's certainly weren't around a decade ago.
