Why do you care? Are you trying to sell these people something? Bottom line...some people arent degenerate gamblers (calculated risk takers) like us. Some people dont care that much about money to spend there time staring at a screen.

A gaussian mixture model isn't really making a strong gaussian assumption, in my opinion (I'm often lose with my definitions...) Another option (not a great one, it's inefficient) is to pose your regression problem as a classification problem using cross entropy loss. The outputs will be a...

I only used it as an example of how you can estimate a distribution as opposed to a single value.

You don't just blindly apply algorithms to data you know nothing about.....unless you like buzzwords. AI/ML bro! Also, every function/process...even deterministic ones have a distribution

Neural networks are all about structure, and you can coax them to do different things by using different loss functions and Input/Ouput configurations. Mean square error, which is what is suspect your using, is the most basic, and it works great if your simply trying to fit y = f(x), where your...

Whats the difference between a false signal and and an adverse draw from a stochastic process? I don't try to filter anything...just estimate the probability of future events. You should be fitting a distribution...not a point estimate. At least that's my method.

I use them. Ill say...if you think youre simply going to train a neural network to make accurate trading decisions, you are mistaken. For me, "the sauce" was figuring out how to properly stage the data for the network and how to combine the network with other tools. Sequence learning can be...

If speed is your biggest concern....checkout dask and/or pytorch. Vectorization on crack....if you have a Nvidia cuda enabled gpu. Dask distributed is also nice, If you want to split your work across multiple machines.

Yes. If you know what your math is..

What's wrong with Excel? Can you really rattle off a formula by voice faster than you could have typed it into Excel and just changed the inputs?

Fortran 90...I used to use that a minute ago when I was working on "bleeding edge" aerospace products...u aerospace?

Notice that this is TEDx and not TED. TEDx are independently organized events, so the organizers could have been anyone... including the clown giving the speech

It certainly is a scam, but I don't think even dumb people are dumb enough to buy it.

This guy is clueless...who gave him a microphone? I mean, seriously...if youre going to get on stage and claim you are a fund manager...pay someone to make you some decent looking charts ....and maybe put some axis labels on there...

You're also trading your own money. When you have no personal exposure....risk management is optional.... allegedly

I wish he'd write a book ....I just finished Ed Thorpe's book, and I'd imagine a Simons book would be equally interesting

How can you say it shouldn't have happened? If the plane is trying to prevent a stall, and the pilot keeps bringing it closer to stall by pulling up while the stall avoidance system is active....the systems response going to become more and more severe. Pilot induced oscillations are a thing...

Okay, when an aircraft is beginning to stall...you pitch the nose down, and trade altitude for airspeed. If youre too low, your screwed anyway (Presumably, the stall system is aware of the ground....) Aerodynamics are complicated and highly non-linear, especially near stall when you start...

Airplane Pilot vs Missile Guidance Engineer terminology, I suppose. The design engineers refer to the autopilot as anything that translates inputs from the "guidance system" (human or computer) into control deflections....at least in the missile world (where there is rarely a human in the...

Well, yeah...but: Its completely plausible that the autopilot was attempting to do the right thing for the flight condition (i.e pitch down), which would seem counter-intuitive to a human pilot. I can't think of a situation where fighting the autopilot would be advisable. To your point, the...
