This problem is actually pretty obvious to fix and you don't even need a neural net - it can definitely be done "old school" computer vision.

Simply detect the presence of "flashing emergency lights" in the oncoming lane and disable autopilot when present. No object detector needed. The signal is so strong it's literally flashing extremely brightly in a regular, predictable pattern - any vision grad student should be able to figure this out.

Could there be false positives? Yep, but very few things will flash quite like that, and most half baked vision engineers can do this. The worst case is literally simply the driver taking over on occasion at night (maybe near strip clubs? lol)

strebler commented on Stupidity is a specific cognitive failing   psyche.co/ideas/why-some-... · Posted by u/mcguire

There is no way round that "stupid" is primarily an insult thrown at opponents, not a statement of fact. As a matter of fact we are all incredibly smart. And stupid too.

With that said, I have a hard time agreeing with the definition of stupidity put forth in the article, as far as I understand it. To me stupidity is that state of mind that one may find oneself in before the first cup of coffee in the morning, or when stress (or ignorance) prevents one from intelligently considering all the relevant facts in a case etc. It is not something I would assign as attributes of persons lest it be someone I really didn't like, or (shudder) groups of persons, nor qualitatively separate from "dumbness".

Sticking to an outdated military tactic has far more reasons than one persons "stupidity", and what's up with mentioning South Africa in the context of "a kind of misguided innovation" influenced by "ideas and terms taken from the United States"?

Looks to me like the author is attempting to accrue academic points on the topic of stupidity, in order to use the insult more effectively against opponents.

I wholeheartedly agree. It's by definition an insult and I don't believe an academic measurement of stupidity (or intelligence) is a terribly fruitful endeavor. "My math says you're stupid!" is a place some people may go with this.

I try to think in terms of bias: "what biases do I possess that may cause me to yield an outcome that is negative?" or "what bias does person X have that lead them to those actions or words?"

I feel it promotes empathy, questioning and understanding. Not name calling. At least, it's helped me to figure out some surprising things about myself and others!

On the topic:

What the heck was Oumuamua anyway? Do we have a good hypothesis for the (apparent) low density / high velocity by now?

What, the elongated, shiny, rotating thing that was able to accelerate without any effect on its rate of rotation? Totally a comet, definitely, 100% guaranteed.

Maybe I'll give TF another try, but right now I'm really liking PyTorch. With TensorFlow I always felt like my models were buried deep in the machine and it was very hard to inspect and change them, and if I wanted to do something non-standard (which for me is most of the time) it was difficult even with Keras. With PyTorch though, I connect things however how I want, write whatever training logic I want, and I feel like my model is right in my hands. It's great for research and proofs-of-concept. Maybe for production too.

TF's deprecation velocity was way too high for my taste. Things we wrote would stop working randomly with their updates. I feel very similar to you about the models being "buried too deep" in their (ever-changing) machine. I much preferred how easy it was to hack Caffe V1 (once you got past the funky names, etc).

These days, I really like mxnet. Torch was a disaster, but Pytorch is much better. It's not bad in production, definitely my #2.

strebler commented on How to hide from the AI surveillance state with a color printout   technologyreview.com/f/61... · Posted by u/hsnewman

Interesting, however this just reflects an overfitted model. Fundamentally, this photo is not that different from a fashion influencer's posts.

We're a fashion engine and our system fully detected both of the people and all of their apparel (the person in question's shirt, his pants and it sees the "printout" as a low confidence handbag, as well as his shoes).

Not to say it would be impossible to trick our system, however, this method would not be sufficient given a good object hierarchy. Our system would have to have a triple miss across two methods - would need to miss his pants and his shirt and his body with the localizer, as well as his pants and shirt with the segmenter. And, if we were serious about detecting hiding people, you'd be surprised how gosh darn reliable the shoe detector portion is.

I don't see it being terribly feasible (and definitely not reliably so). Let's just say, it's not even close at all at this point. We miss zero of these things today.

strebler commented on Facebook Has Got an Instagram Problem   musicindustryblog.wordpre... · Posted by u/imartin2k

I didn't quite understand, what is the problem with Instagram? It's too popular? Or just that it's not dropping in popularity vs Facebook (due to their recent adjustments)?

I wouldn't consider Instagram to be a messaging app - in fact they're spinning off another app from Instagram just to do messaging (because it's not exactly great at that).

It sounds to me more like Facebook might have some problem and Instagram is just doing it's own thing (as are Facebook's other services).

strebler commented on Why Don’t the 20 Cities on Amazon's HQ2 Shortlist Collectively Bargain?   theintercept.com/2018/01/... · Posted by u/rohanshah
optimuspaul · 8 years ago
I tend to agree that this is a dumb idea... but think about this. There are a few clusters on the east coast, the clusters could work together to push amazon to one of the other cities in exchange for deals that help the others out.

If I'm being totally honest though I don't think there is much advantage to any of the cities to give Amazon incentives to picking them. I also think that Amazon has already decided.

strebler · 8 years ago
That's definitely possible they've already more or less decided. Either way, they're pulling off an impressive optimization to obtain maximum taxpayer funded subsidies.

Whats up with those US prices, Humalog more than $250 per vial? In Europe (Finland) non-subsidized price is $34.
strebler · 8 years ago
That's incredible. Humalog is a quite similar low price in Canada. It's strange that it'd actually be economical for many American diabetics to just book a (yearly) flight to Canada and buy 12 months worth of insulin.

This is a really good article, I'm impressed. If you read only one deep learning article this month, make it this one.

I'm going to borrow that analogy of "teenagers perceptions of sex" - it's hilariously accurate for deep learning.
