Any good resource on statistical probability theory notation and how to simplify/solve such expressions?
Like what the fuck is that notation?
What level of abstraction do I have to work with here. Where do I plug what?
>>
>>12970315
Which parts seem non-standard to you? Is it the Pr(dx,dy) or the conditional expectations? For the former, you can get reasonably far by just interpreting Pr(dx,dy) as an integral over the joint density or sum over the joint probability mass function -- e.g:

[eqn] \int [y - f(x)]^2 Pr(dx,dy)
= \int [y-f(x)]^2 \varphi_{x,y}(x,y) dx dy [/eqn]

Where phi is the joint density. Conditional expectation should really be learned on its own. If you've had a first course in probability I'd recommend Grimmett and Stirzaker's probability and random processes if you just want the meat, or Durrett's Probability theory if you want the whole thing with measure theory.
>>
>>12970885
I guess I should also mention that the reason that notation is used (Pr(dx,dy)) is because modern probability is built on measure theory, which uses different kinds of integrals, hence the different notation.

Supposedly this book has exercises in the following webpage:
deeplearningbook.org
However the github it links is nearly empty of any exercises.

Where can I find exercises for each chapter of this book? Or another book of the same quality but with actual exercises?
This book is damn perfect except for the fact that it doesn't have any exercises

What's the best way to get a good grasp on it?
I know a large part is remembering the distributions, but a lot of those equations look ugly as shit like the normal and chi-square distribution.
And also, is statistics worth it?

All of these questions depend a lot on what you do, why you want to learn stats, and how much math you know. Also, almost no one sits down to memorize the distributions. That just comes naturally with time.

Are you intentionally trying to act stupid or just plain stupid?

All rigorous results and methods in statistics can be stated in terms of probability. The two don't separate when you try to understand them.

So /sci/, I want to learn how to make hand/arm/leg robotic prosthesis, little robots (like link below), and quite possibly later on the future being able to create exoskeletons and robots like the ones of Boston Dynamics.
What exactly do I need to learn in terms of programming languages/ specific electronics/ physics? Can you guide me on this one?

Art school

Is there any mechanism within a reasonable amount of deviation from current physics that can lower the speed of light within a vacuum for a given region of spacetime?

I can theorize some effects this may cause, for example, decreasing c would impact both electromagnetic constants in Maxwell's equations by some factor n<1, making electric fields n times stronger and magnetic fields 1/n times as strong. The fine structure constant α would increase, therefore making larger structures such as large atomic nuclei or larger molecules unstable are α gets larger. Reducing c also causes nuclear energy production to decrease as per e=mc^2, making stars shrink as they reach a new equilibrium with gravity.

As for the mechanism for lowering c itself, I originally though by inducing photon mass through the Higgs Field or by creating a scalar field that induces photon mass, c may be lowered, but it appears that the speed a photon travels does not affect c.

Any thoughts?

No, not even close.

>>12969921
Began vaccinating in mid to late December. Three weeks before second dose, two weeks after second dose before full efficacy. So five weeks out from mid-December puts them at late January before first mass-vaccinated people reach peak immunity. Deaths began steadily falling after the maximum spike in deaths in late Jan/early Feb. I see nothing wrong with this timeline.

In general does anything in nature have meaning if you take the 3rd derivative of higher? I'm referring to jerk and snap when working with rate of change of position with respect to time and so on as you deal with acceleration it's clear there is still meaning but at a certain point the derivative is meaningless. Can someone give an example of a 3rd or higher derivative that is important for a real world problem?

>>12968954
A question I've been asking myself alot lately in the context of electromagnetism. as a statationary charge is an electric field, a moving charge is a magnetic field and an accelerating charge emits emf, what happens than if we talk higher orders? what does a jerked charge do?

The Taylor series approximation can approximate a function via point wise expansion, which gains accuracy with higher order derivatives added

Am I the only one that thinks that abstract theory of algorithms is sketchy as hell? It's almost entirely based upon a thesis that can't be properly proven.
>>
Nah Church Turing thesis is true.

Also look up Wilfried Sieg, he has done some work attempting to formally prove the CT thesis
>>
>>12970557
First you can't prove CT, it's a phenomenological statement akin to physical laws. Do you prove Maxwell's equations? No, you make experiments to try to refute it.

Second, it does not even matter. Even if we were to discover a supercomputational device, it wouldn't change the results since they are relativized to the class of Turing-complete computations. FYI there is actually a whole subfield dedicated to the study of computation when extended with non-computational primitives, see e.g. Turing degrees.
>>
CT is one of the greatest mathematical discoveries of the 20th century.
