if by “built by some kids” you mean farmed out building an application around some algorithms licensed from SRI

yeah sure, a statistical model of the solar system is a pretty good predictor for eclipses. thats kindof what we've had since millennia (more or less successfully)

it is incredibly dumb since it is literally a curve fitting task for which machine learning is both overkill and pretty bad.

have there been examples of adversarial approaches that limit access to the network they're trying to spoof? presumably a real adversary isn't going to hand you their model and give you a week's unrestricted cluster time running them against each other - what's the minimum attempts you can use to turn a gun into a turtle?

there's a bunch of "black box attacks" that work this way, only seeing inputs and outputs

often you don't even need those, though, because adversarial attacks usually transfer between networks. so you can just train your own model, and as long as it's even vaguely similar to whatever you're attacking, images that trick it will probably also trick your target

it also helps that transfer learning is common in vision so you can expect whatever you’re dealing with to be some fine tuned head on an imagenet base

wow, how rude

these are the bugs that I discovered while doing my protest:

• after a while google started showing adversarially altered images, which is blatantly ableist against people with bad eyesight
• it can get stuck in a “check also the newly appeared images” but all images are blank state
• the unusual traffic decision occurs before checking if the solution was correct

has nobody tested this poo poo??

fun fact: there are more than 120 breeds of dog in imagenet, out of 1000 categories total. they're wayy overrepresented compared to everything else in there.

The thing that grinds my gears is how they don't specify what percentage of a square needs to have a traffic light in it before I make a click/no-click decision on teh box.

I mean, is "Click all boxes where >=25/33/50/67/75% of the box's area is filled by a traffic light (or sub-assembly thereof)" really so loving hard?

:mad:

E: Also poor documentation on whether or not pedestrian crossing lights (not signs) attached to traffic lights are to be considered as traffic lights for the purposes of the above.

okay, so, first thing you gotta understand is what people mean by "deep neural networks".

inputs get multiplied by weights ([10, 300, -.5]), then summed, and passed through a nonlinear function. the function we're using is called ReLU, defined relu(x) = (x if x > 0 else 0). you might think thats a lovely function but it's super common in deep learning for some loving reason

multiplying two inputs with *each other* without using some specialized blocks is the hard bit. multiplying inputs *by a constant* and adding them up with some clamping function applied is the basic building block.
