why does the existence of such problems disprove the existence of a mathematical foundation? A well-founded mathematical foundation would prove/predict/explain why such problems don't "fit" with the "structure

My thesis was on Generic Algorithm. I stopped and started working on Deep Learning mainly because like you said, GAs don't really have a strong mathematical foundation. Ironically, no one could really explain why CNNs work mathematica

Here's what my hypothesis: when it's physically impossible to stop (which sounds like it was the case, car moving at 38mph and you have a split second), my hypothesis is that the robot would plan to swerve around the obstacle inst

What prevents 10 of us from surrounding a real truck, walking in, forcing the driver out and driving off? https://xkcd.com/1958/

hmm, Im not an expert but isn't your logic based on constant supply/demand? Once self driving trucks become mainstream could it be that truckers will do fewer long trips but more shorter trips which doesn't necessarily lower

What you probably don't know is that this is a problem with almost ALL tech companies in general. Early Facebook engineers can look up ANYONE's personal information. Same with Google. There was an article a couple weeks back about

If you look at the settlement number, 0.34% of Uber at 72B (yes, 72B, not 45B as the recent down round which would equate to 150M), then you'll see that Google did not expect to win this case.

not necessarily. The convergence point can be and will probably be sub-optimal if we keep doing this without a mathematical framework guiding us.

that's just an aspiration, not mathematical foundation.

That is not true. What you're describing is called zero to a few shot learning in the literature and there are specific benchmarks to test this. The author(s) specifically chose to NOT test on these benchmarks and there is no explicit

The idea might be cute but performance is not there yet. Specifically they were able to achieve state of the art performance on MNIST, but got 10.6% test error on CIFAR 10 which is comparable to state of the art of 4 years ago (and if you&#

He has 6.5 BILLIONS. That's almost double what Brian Chesky (CEO Airbnb) has including paper money, more than Evan (CEO Snapchat) has, and more than Travis (CEO Uber) has including the ridiculous valuation. Just an observation.

You're thinking about the tail end of the distribution. If self driving cars can solve 90% of the mass of the distribution, i.e. driving on highways and urban streets, it would be a significant improvement in terms of efficiency. Of co

AFAIK, tesla doesn't use lidars. This one has at least 2 lidars, so there's that.

by inverse_pi 9y ago
hmm I thought the bottleneck would be on the software side? I saw at least 2 lidars (possibly 3) on the car in the article. Of course we don't know if that's sufficient for L4, L5 but other companies are running with only 1 lidar.

Competition is good. I would be really worried if Waymo is the only one demonstrating their visualization capabilities. It also encourages more showcase of technologies which is generally good for the public. SDC has been too secretive of a

Unpopular opinion: I hate the tipping culture but I love this change. Here's why: I never rate the drivers right after the trip unless the ride is REALLY good or REALLY bad. If it's really bad, I want to express my anger. If it&#x

exactly. In fact, I was really surprised when I saw B9. It could have played at B11 which was a 15 point move. But it decided to play safe because B11 even though big in point, would give back strong safe in the center. (it also lost 2 poin

3-3 invasion means you're giving thickness to 2 sides. After studying the 60 master games I concluded that 3-3 invasion only makes sense if you can make the thickness on BOTH sides inefficient (AG only played it when it has stones on b

Uber's stories generate a lot of clicks, impressions and ads revenue. Everyone wants a piece of that pie.

No, they're also claiming that their LiDAR is "fundamentally different" than Waymo's.

well they're losing billion of dollars every quarter so I'd say pretty often.

No I think you've got it wrong. Drivers are paid by miles and minutes after the trip is done. It's like "I'm a contractor you've hired to remodel your house. I tell you that I can get a plumber to do it for $5,000,

I think you're misinformed. Uber tells the rider the ride will cost $5. Uber doesn't tell the drivers how much the ride will cost until the trip is finished. Then the fare is calculated based on miles and minutes. If the fare ende
