My source is a chat with several engineers at companies I cannot disclose. I also used to work for a company that develops autonomous navigation solution. If you have on the order of 10 LIDARS on your vehicle and same number of cameras and

Power per operation is certainly decreasing, not as rapidly as in the old days though. However, it is completely not clear how much compute power is necessary for sufficient level of cognition that would allow L4 autonomy. Experimental cars

They will deliver some sort of slightly enhanced autopilot that will be able to drive autonomously in few areas and require constant attention in all others, and announce a major victory. If you think level 4 driving AI is just a software p

If what you are saying was true, then why all these skills require time to develop? If they are pre-programmed in the DNA, why are they not enabled on the day of birth? Clearly from evolutionary point of view an infant that is already able

Your statement is exactly the incarnation of Moravec's paradox. You don't see the amazing things that a 5yr old (even a 2yr old) can do, exactly because these things are completely obvious to us. They become much less obvious once

Except that by the age you reach school you already know amazing wealth of knowledge about the world and how it works, particularly the kind of commonsense knowledge that AI has always had enormous trouble to acquire. See Moravec's par

And therefore obviously this is not an unbiased control group. Perhaps the more recent teslas have slightly better/less used brakes? Have they controlled for that? There are countless ways in which such conclusions can be flawed. Stat

I was thinking about the Chinese boy who hit the truck parked on the service lane, not the guy who decapitated himself in Florida. But either way, both were tragic.

How can autopilot be involved in a fatality when used correctly, when by very definition the correct use implies alert driver who is responsible for everything that happens?

I don't think the argument here is whether technology features can improve safety. The core of the argument is (and always has been) over misleading marketing and naming (suggestive "autopilot"), which exactly encourages the

Obviously this truck may have broke down in that lane and could not be moved out, which removes the fault from the truck driver. In general cars have drivers, exactly because such things can happen and will happen without anyone else to bla

I know this report. This does not deal with the bias problem however. Obviously it reduced the number of accidents in good road conditions where the autopilot works and is primarily used (much like auto-stop feature did and BLIS). Particula

"the number of fatalities that have occurred with autopilot active compared to the amount of miles driven with autopilot active suggest that autopilot is safer than a human driver." Obviously you see how this deduction is subject

I'm not upset, but A1234 looks like a chip name, "pentium" is not a dictionary word, fine. But "bionic" has a meaning, following the dictionary: bionic |bīˈänik| adjective having artificial body parts, especially el

"Bionic chip"... what on earth is this supposed to mean? Are they running out of fancy PR words in the dictionary?

No. They had plenty more. Approximately 100 cases over 600k miles last year (their own data from California) which would have lead to a dangerous situation, and 9 cases which by their own admission would have resulted with a collision. Now

Evaluating technical capabilities in autonomy based on youtube demo videos is like evaluating the military potential by watching army parades on holiday. The truth is, none of these companies is any close to full autonomy. Full autonomy _te

Saying that self driving car hardware problem is solved and all we need is software is like saying that one solved the problem of building interstellar space ship. All they need now is the warp drive. Otherwise it is all solved...

Once they actually have cars driving empty we will actually learn how close or how far are they. I've seen a lot of PR muscle flexing from big companies before and no longer believe any such stuff. They do that to impress investors and

How can they prove it was me who waived that right if the data used to identify me was breached by them and potentially publicly available? The snake is eating it's own tail here...

But sometimes getting 70% larger sample will cost you so much money, that you'd need another grant, one you'd get after you'd publish your p=0.05 result, which given the new rules you'd not be able to publish... Statisti

I agree with that. In my prediction legitimate, honest research with p~0.05 will become unpublishable, while p-hacked bullshit will prevail in glory.

by felippee 9y ago
The problem is not the value 0.05 but researchers cheating with their data. If researchers were honest, by the definition of statistical test 5% of papers should turn out to be actually false. If that number is more like 30% it only means t

You mean like this one? http://www.astro.yale.edu/astrom/spmcat/histov.html Not really. Plus keep in mind magnitude is a logarithmic measure. Things get skewed when you take logarithms. Also if you look for exampl

But the variance needs to be bounded. With power laws is is often unbounded. The trick that many get trapped in is that short samples of power laws typically look regular. Estimates of variance will always be finite on finite sample size. N

The origins of that analogy are very flimsy: 1) Hubel and Wiesel discover simple and complex cells in cat's V1 in the 60's. They came up with an ad hoc explanation that somehow the complex cells "pool" among many simple

Yes, this is very cool stuff and I've been advocating for it in previous posts. There is indeed the problem of prediction. Prediction seems to be an omnipresent paradigm in many aspects of perception, even in early vision. This, contra

As with all complex matters there are numerous considerations and issues with all of these. Moon is close, we've already been there, escape velocity is low but there appears to be very little water, not very accessible at least. The da
