Agile done wrong destroys more than Agile done right can fix. If you feel too good, or too senior for a programming methodology like Agile, then you are bound to not like it. Is that a fault with Agile, or a fault with your attitude? A cowb

I do not think logic-based learning is dead. It just smells a bit funny. In the vein of the papers "From machine learning to machine reasoning" and "Text understanding from scratch" I expect a "First-order logic und

I think those quotes were a bit snotty, especially considering your stature and knowledge on this. I don't think I was trying to rebut you, as much as I was simply trying my luck at advocating that user's view. Sorry for that.

I do not think there is a one-to-one connection to be made between neural nets and the brain. That said, it is possible to fool our own visual system in a similar way: http://en.wikipedia.org/wiki/Gestalt_psychology#Pro

But maybe what they did today makes that impossible. They set the whole thing on fire, and now maybe nobody is going to trust it because they’ll think there’s some big evil vulnerability in the code. But now this decision makes me feel lik

As far as I can gather the Dutch authorities are not able to retrieve TrueCrypt keys. I can not say the same about BitLocker and FileVault. If the US knows how to get into TrueCrypt volumes then at least they are not sharing that knowledge

Do not be silly. Turning a bug like this into a commercial venture? How do you find customers fast enough before a patch? 6337$ for a days work is very reasonable, while selling a bug like this makes you not worthy of a quarter.

Very interesting. Thank you for correcting me. a relatively large fraction of examples will be misclassified by networks trained from scratch with different hyper-parameters (number of layers, regularization or initial weights). The above

I was not talking about overfitting. I've seen that paper. The original paper asked if images that could fool DBN.a could fool DBN.b. The answer was: certainly not all the time. They used the exact same train set and architecture for D

Deep nets are only loosely inspired by neurobiology. That's why LeCun calls them "convolutional nets" and not "convolutional neural nets" and prefers "nodes" over "neurons". It is, however, possi

Now I have to try this out. My intuition tells me it becomes increasingly hard to create a fooling image, which looks alien, and is able to fool all the nets in the ensemble, even though they have different settings and params. I think they

If we have a singularity AI then we don't need CAPTCHAs: For all intents and purposes an AI is equal or superior to humans, there is no distinction to be made. The Turing Test is a form of CAPTCHA. Also, one could make CAPTCHA's i

It is good to know that they need access to a lot of predictions from a net, before they can create an image that will "fool" the net, but look alien to humans. Secondly, this doesn't account for ensembling: "fool me onc

Yes, if you want to be sure that your solution is correct, you must run the compressor yourself. Then you count the number of collisions it takes to happen upon the correct solution and feed this counter to your decompressor. But then you p

Blast! That would require our solution to break all known encryption. Then it would be easier to just target Goldman's setup. A file with output from AES-256("sekrit") would not be random to Goldman. It would appear random to

Chances of getting a collision is higher than getting a good solution, but having multiple hashes does help in increasing the chance at a good solution. With a hash 1 bit less than the length of the file, we put two pigeons inside one hole,
