<Iskierka>
oh yey course using scipy/numpy/jupyter
<e_14159>
I'm quite distracted and busy (ICML deadline in 10d~4h)
<SnoopJeDi>
Heh, relatable
<e_14159>
Extremely interesting paper, thanks.
<e_14159>
I'd slightly criticize their use of the L_inf norm, but it's an interesting attack from a not-quite expected direction.
<APlayer>
But what sort of actual attack could this be?
<SnoopJeDi>
I confess I've not done more than skim it, but the relative size of their δ is fairly shocking to me (as well as the fact that silence is a producible target)
<e_14159>
APlayer: You mean in practice?
<APlayer>
"Let's fool this Alexa device and play a tape that sounds like it orders a computer, while in reality, it orders a microwave!"
<SnoopJeDi>
Or perhaps fool Messenger and its kin into not recording every gorram thing you say
<SnoopJeDi>
(I mean, not *really*, but...)
<e_14159>
Imagine an "AI program" (oh how I hate myself for saying that) listening to your communications for stuff somebody doesn't like. Instead, you change the signal such that it hears something else.
<APlayer>
So, when Alexa orders a microwave and it arrives, you've got to file a lawsuit against Amazon and insist that you actually ordered a computer and were shipped the wrong item. Present them the Alexa recording as proof. Collect a free microwave with the computer you actually ordered.
<SnoopJeDi>
The construction of the attack is not really specific to audio, mind
<SnoopJeDi>
I've seen a paper or two on adversarial attacks on visual classifiers
<APlayer>
Still the bermuda triangle of maths to me
<SnoopJeDi>

<Qboid>
SnoopJeDi: Weapon added!
<SnoopJeDi>
APlayer, if you can get your head around the idea that a flat piece of paper can be wound up into a cylinder, you already have a pretty good intuitive concept of manifolds :P
<e_14159>
Anyway, I have to go to sleep.
<APlayer>
SnoopJeDi: This seems to be one of the few cases where intuitive concepts are nowhere near enough for a semi-understanding of mathematical concepts
<SnoopJeDi>
(and Spivak's book is seriously really good!)
<SnoopJeDi>
APlayer, it seems that way but it's not
<SnoopJeDi>
nn e_14159
<e_14159>
"Pages to write before I sleep", or how did that song go again? :P
<SnoopJeDi>
I just realized "nn" could be "night-night" OR "neural net"
<e_14159>
I had assumed that to be intentional
<e_14159>
But now, for actual sleep. Night!
