In a similar vein, and perhaps even more useful, here is a collection of probably 100+ useful concepts and thinking tools (make sure to read all comments and also the comments in the linked article at the top): Concepts for Your Cognitive

I think this is basically the major and effective meme/emotion that Trump plays into: Nostalgia. Thiel also voiced concerns about the state of the infrastructure at a GOP Convention. Nostalgia is a strong emotion and it is often based

But MCTS works in AlphaGo because the 'world' can be fully represented by a tiny state vector which fits a billion times into primary memory these days. The real difficultly of real world problems is the ill-defined, mutable, high

Remember that arXiv is just pre-print and the last page if not the entire paper is probably nothing more than a lame/distasteful joke. Remember that any nutbag who knows a little English and LaTeX can publish on arXiv. It will likely n

AFAIK it's not so bad at large scale and with brains only.

I am not seeing it. People are following the super stimuli of rockets, history etc. while further contributing to pollution and resource depletion. We need a culture that is satisfied with much less, one that overcomes the tragedy of the co

It's almost certainly irrelevant for our survival, but it's also not expensive enough for me to care.

Yes, I think the same about deep sea exploration.

by hacker42 10y ago
Perhaps I'm a bit cynical, but space exploration strikes me as a waste of money and energy. The universe is clearly no good for space travel, otherwise we would witness aliens visiting us. It's empty and hostile. This planet is th

Why? Leftist people would also get more diverse recommendations. They'd be exposed to arguments such as the importance of maintaining western values etc. I actually did an experiment of wading through videos recommended based on anti-M

I think personalized media might bring information bubbles to a whole new level because recommendation systems are more efficient and achieving millions of YouTube views has arguably fewer intellectual hurdles than achieving similar reading

Do you study the phenomenon of information bubbles at Google? Let's say, a German user just happens to watch some right-wing populist video claiming that we need to stop Merkel's refugee politics. The next day the user might rec

I also dimly remember that sparsity in the random fixed backward connections still works. There is actually a figure about that in the paper you've linked to. Interestingly, feedback alignment is also patented, but it is unclear that i

It will be an approximation of the Jacobian because it is just backprop. It also seems they only use the linear model when they also condition on the correct class which makes things easier. It is also only MNIST (10 classes).

It is obviously inaccurate to write "nobody" and I am sorry if I have hurt your feelings by this rhetorical device. I've merely pointed out a general tendency that Islam numbs social, economic and scientific progress, i.e. th

The illusion is actually measurable. For example when you cause activity in cortical motor neurons by direct stimulation, then the subject will move e.g. their arm involuntarily, but they will later convincingly explain that they've mo
