Basic probability is very helpful: Expectation, Standard deviation, P(A and B) = P(A)*P(B) is A and B are independent, P(A or B) = P(A)+P(B) if A and B are mutually exclusive. Also, knowing algebra is very helpful.

In a way, you don't really need to know much more because there is a lot of good software out there.

If you want to learn more math, learn Linear Regression, Logistic Regression, p-values, probability density functions, cumulative density function, the Central Limit Theorem, Gaussian Distributions, Exponential Distributions, Binomial Distribution, (maybe) Student-T distribution.

If you want to learn even more, first learn matrices (adding, multiplying, inverting, rank, span, matrix decomposition (SVD, and eigendecomposition are the most important)).

If you want to learn even more, it's time to learn calculus. Integral calculus is needed for continuous probability distributions and information theory. Differential calculus is needed to understand back propagation.

There are a lot of other good suggestions written by the other commentators.

I strongly disagree. Uber has markets that make money and they release new services all the time. There are ways for them to stay in the black if they scale things back and fine tune different markets.

Someone is going to be the first in self driving cars. Uber has a tremendous demand for them. It would be stupid to not at least be trying to be the first one on the scene.
It depends. All that is essential for an autombile engineer is not essential for a taxi driver.
...which, of course, defeats the point "I did something insanely dangerous and did not die". Is there a way to increase safety while keeping the feeling of danger? That sounds like a contradiction to me.
>some dude from Toyota, who don't seem to be very invested in this space, tell me he doesn't think it's going to work isn't very convincing

Similarly, opinions from those heavily invested aren't convincing.

I'll try to restate the point in my own words and see if that helps you.

"just world/character-building" would be if the plot was: a girl gets a soda from a soda machine, then take it to a boy. Kishōtenketsu is: a girl gets a soda from a soda machine. Meanwhile, a boy sits on a bench. The audience is confused at this point and that creates conflict in their mind. In the resolution, we see the girl was getting the soda for the boy.
A slight correction: according to some measurements that I found [1], the ambient illumination during totality is roughly 2-5 lux, which is "only" about 45dB below normal. (Full daylight is about 10^5 lux.)

I started researching this a few weeks ago after seeing a Reddit comment asking (paraphrased) "my house is just a couple miles outside the path of totality, is it really worth the trouble of finding a different spot to view the eclipse?" The answer is that even at 99.5% occlusion, the sky is still hundreds of times brighter than complete totality.

The governor told people to leave. The mayor told people to stay. One of them isn't going to be reelected next term...

Probably what should have happened (I'm using my perfect hindsight here..) is they should have told people living in low-lying areas to either go live with relatives or friends who were on high ground, or leave town altogether. And everyone else to stay. This would have prevented the mass exodus that clogged roads during previous storms, but gotten more people to safety.
I think Toyota exists in a different dimension than the rest of us. Toyota is so convinced that the future of cars is hydrogen that their electric car efforts boil down to a four man team. Dinosaurs! As for self driving tech wasn't there a successful multi manufacturer trans Europe truck convoy last year? Self-driving tech is already at work at mines. Decades? Really, Toyota.
I haven't seen any Nazis completely ripping up a town like Antifa did to Hamburg, so yes, actually, Antifa is shit and we should be rid of them sooner rather than later.
I was watching a movie last night, where in the opening scene, a getaway driver escapes the cops. In the meanwhile, the driver, seemingly randomly, kept listening to the score of the local football game. At the end of the chase, the driver pulls into a parking ramp where the game has just ended - obfuscating his vehicle in a sea of fans leaving the game. (It's worth noting that there's still conflict, but this was the first example that came to mind for me.)
It's different because there is no apparent obstacle that blocks the protagonist (the girl) from achieving their goal. In traditional western plots, this conflict is the main focus, and is usually between the protagonist and an antagonist who has their own (usually opposite) goals.

This conflict underlies almost all the narrative structure. For example, the reader should be obsessing about the stakes as they read: what happens if the girl doesn't get what she wants? Who else loses? Does anyone die? This is what drives people to read on. Without conflict, this structure falls apart.

World and character building can occur in either of these cases. But in the classic conflict case, the world and characters are usually designed to heighten conflict (ie. the character has a flaw that leads to them to more direct conflict).
Maybe for this particular investment, but I'm pretty sure the wider intention was to legitimize business practices where the poor live tenuous lives as an app-directed servant class. Uber made this kind of neo-feudalism so socially acceptable that we now celebrate "Uber-for-X" as "innovation."
Seriously? Google docs has far, far less functionality. Have you tried, for example, to insert auto-numbered equations or images? There doesn't seem to be a way to achieve that. That's not a corner case. The spreadsheet also chokes on data that excel can handle. Google docs is fine for maybe 80% of use, but I wouldn't call 20% "corner cases", and to cover them will take way more than 20% the effort of building MS Word.

Planes have been automated to some degree for 100 years. Fully automating a plane at the equivalent of Level 5 is almost a trivial problem compared to doing so with cars. The reason planes aren't automated is mostly social, not technical. Whereas with cars it's decidedly both.

Yep. We have to keep in mind the distinction between "applied ML" and "ML research" (while realizing that this is a continuum, not a binary distinction). Not everybody is doing cutting edge original research... some people really can just get by with downloading DL4J, reading a few tutorials, and then applying a basic network to their problem, and create some value in the process.

I think cars are a good analogy. In the early days of automobiles, you needed to be something just short of a mechanical engineer to keep one going for any length of time, and it was routine to need to carry around tools and spare parts to perform significant repairs. You really needed to know a pretty good bit about how the car worked to use it effectively. But over time cars developed better abstractions and became more dependable and it became possible to operate a car without caring one lick about how it works, beyond know that it needs gas (or electricity!) and taking it in for the occasional tuneup /tire change / alignment / etc.

I wouldn't say we're at the point yet where ML afford one the opportunity to be completely divorced from caring about the underlying details, but I think we are at a point where you can legitimately get useful stuff done without needing to be able to, say, derive the equations for backprop by hand.
> a car misread a stop sign with a small amount of marking as a 45MPH speed limit sign

That's what happens when the sign were made for humans. They should start putting QR codes under traffic signs, with the human sign as a fall back or as a second point of reference.

I think the mouse is a dead end - but I think interactive Gui with pen and touch input are not. I recall there's been studies that show editing with the mouse is faster/more efficient than keyboard/modal-driven editing - and even as an avid Vi(m) user I can believe that.

But I while the mouse is dangerous (due to rsi) and limiting (five fingers become 1 to 3ish buttons) - I don't think the keyboard is the best we can do either.

I actually think the direction Ms is taking with surface and wheel is very interesting.

And for a while, I've believed an acme inspired (multi)touch&pen interface is likely to be a good way to take user interaction a step further.
A lot of data is best represented graphically, and while you can shoehorn this sort of data into a vector space by projecting using a graph distance metric, the results are likely to be inferior.
> "Bayesian Data Analysis" by Andrew Gelman is another great read.

If you want to read that book you need real analysis more specifically measure theory (unless that subject is in probability theory for you). You cannot get into the last few chapters without it. Dirichlet Process are described using measures.

I don't believe you need multivar calc or info theory. Info theory stuff are used but not as often. I believe you're slanted toward researcher phd position. Gini index, entropy, etc... and such are taken as given when needed.

People have a habit of thinking linearly, however technology builds on top of technology (leading to exponential improvements).

Half way through the Genome project, they had only mapped out 1% of the genome. A lot of people in that field and working on that project were thinking the same thing - "not even close". But the next 7 years, they completed the next 99%. This is the power of exponential progress.

The only thing that is going to halt this progress is to hit physical limits and not find a new way of doing things to get around the physical limits. New technology opens new possibilities.
I guess that you are not using them correctly then:

"This became painfully obvious with the article floating around where a car misread a stop sign with a small amount of marking as a 45MPH speed limit sign. It's pretty clear that if a car is mistaking a red sign for a white sign, we have a very long time to go before the car can safely drive itself without a human observer to intervene when needed."

I think you misread that article.

Someone built their own toy implementation of an CV sign recognizer. Then, with full access to the code, they reverse engineered visual distortions that could seem innocuous to humans but trip up their model.

It's not a real world issue as far as I'm aware (though obviously signs can be misread or missed, but not invisibly vandalized)
The trouble is that only the most engaged minority of users would be willing to pay for the service directly. What I'm interested to see is whether we can build services where the people who care most end up covering the costs for the rest of the users. So you pay $5 for a facebook-like service that then provides free services to everyone who knows you. You would have all the same funding problems as other public goods but there are plenty of them that make it work. Of course, even if something like a public radio or other public support model would fund a social network sustainably, you would still have the network effect problem in terms of getting people actually switched over.
I think it's worth considering what sort of incentives are created by such a deal.

That's not because you need little background in information theory. That's because KL-divergences are such a universal info-theoretic quantity that if you deeply understand them, you understand much to most of information theory.

This is like saying, "You don't need to really know calculus, just integrals."

>> draw government funds away from transit projects that would be a far better investment.

Not just government funds, but also car maker funds. I honestly don't understand why all the research in automated driving doesn't focus on making better versions of the driver assists we already have first, instead of shooting for full autonomy, which I honestly believe to be a pipe dream.

Of course many of the advances in researching autonomous driving will trickle down to safety systems for 'normal' cars, so that's a good thing. I just feel like everyone is approaching the problem from the wrong direction, wasting a lot of R&D effort that could have produced much better results much sooner if car companies would start from what we already have and incrementally improve it. You can blame car companies for being slow to adopt many things that could benefit all of us (such as electric drivetrains), but you can hardly deny car safety has already improved tremendously in a relatively short timespan. Whether they were forced by regulation or because they thought making safer cars would be more profitable doesn't really matter.

I often see this talking point come from a certain segment of people with particular persuasions. It is extremely peculiar that you chose to link to a Daily Mail (I cannot articulate how ironic that is) article that uses another talking point/myth that's been appropriately cast aside again and again. Just for an observable example of the nature of the people that hold these persuaisans and view points, you can gather a list of subreddits that have submitted this article on Reddit and compare which subreddits it garnered attention on and which ones, again, appropriately cast it aside: https://www.reddit.com/submit?url=http%3A%2F%2Fwww.dailymail...

Is there any record of Snopes not living up to their stated goal, or doing anything that should have damaged their reputation as an organization?
I think it is because there is also a lot of value of just assisting the driver.

It is much more comfortable to drive if the car itself keeps the same speed as the car in front of me and follows the road. I also feel a lot safer if my car would automatically brake if I'm distracted and a kid runs out in front of the car.
Bingo. You can't pretend to be anything in a Waffle House. You are hungover, we know it, you know it. Who cares if you drove up in a Bugatti? You're still eating dollar fried eggs and dollar coffee just like the rest of us, you just can't showboat.

This is Hacker News. Open source is generally appreciated here even when there isn't a direct, concrete benefit to most end users.

But if you're here, there's a good chance you're the sort of person who could get an AVR programmer and tweak something if you don't like it. Different modes? Timed stepdowns to prevent overheating or not, or more sophisticated thermal regulation for the attiny25 based drivers that have a temperature sensor? A firmware with completely different behavior like near-continuous ramping instead of fixed modes?

It's hackable, and hackable is good.

Sure, but this isn't due to capability, but for regulatory reasons. As far as I know, the firefly vehicles (the cute little bubble ones) don't have steering wheels, and were in use 3 years ago. This argument doesn't make sense to me.

Maybe this is where regional differences come out as most students in the UK have had some programming lessons before starting uni

At the level of professional-standard software architecture for UIs?

There have been some positive efforts in the UK over the past few years to introduce programming as a more serious subject at secondary school level (roughly, ages 11-18). I think it's great if kids get to write a simple mobile app to chat with their friends or make a simple game, instead of only learning things like how to use a word processor or graphics program. I think it's great if there are teachers in schools who themselves have the skills and knowledge to help the kids do that, too.

However, there are plenty of new starters entering the industry who have just graduated with degrees in CS or related subjects from good universities and still won't have been exposed to these kinds of ideas at more than a trivial level. I'd be surprised and impressed if I had a school-leaver turn up for an interview for a programming position with more than a passing knowledge of these subjects.

For what it's worth, I don't think the original author does themselves any favours by inflating their experience as they do. The way they describe themselves in the introduction on their web site seems rather out of proportion to their actual experience, and their CV screams "I read a guide to how to write impressive-sounding CVs and I'm trying way too hard". But as a card-carrying member of the "I thought I knew everything at the start of my career and tried way too hard" club, I think you just have to see that as a combination of genuine enthusiasm and understandable immaturity, and give them credit for having a go and sharing their experience. I'm happy to see someone at that stage in their development taking an interest and spending the time to experiment and discuss and learn, and surely we should all be encouraging the next generation of programmers along that path?
All of statistics and machine learning involves lots of integrals and derivatives. For example: expected values are integrals, and model fitting is done by hill climbing in the direction of the derivative.
