I've read a wonderful paper on what information people use when driving, it is pretty similar to this driving simulation. The basic cue is "where you will be in T milliseconds", extrapolated using the current vehicle velocity

The original article has the same error in the title. x^(-1/2) is the reciprocal square root. The fault is with math notation where rasing x to a negative power, i.e. x^-a means 1/(x^a); while inverse function F(x) is written F^-1

Those videos are amazing. Analog computers are computing by analogy, eg. rotation speed represents variable A, and the roatation position represents the integral of A. Programming an analog computer means setting up an analog of a system of

One option is starting to learn about DL from the big picture, then filling in the details as you go along, eventually going to higher math. I prefer this approach to the opposite where you first learn math foundation and then the implement

OOP could only have been inspired by the then-available knowledge of cell biology, and it seems that even today we still have a lot to learn.

I had a very different reading of the article. The author acknowledges that books do work after the reader actively engages with the topic, does the exercises, rereads, etc. The issue is that this process of transmitting knowledge could b

There are many developments relevant for cybernetics that were not mentioned in the book Cybernetics, like discoveries of H.S. Black and other engineers in Bell labs, or early mechanical analog computers. Here is a short review of book on t

Control theory certainly predates Wiener's cybernetics. He did not invent negative feedback analysis nor design of control systems. He did fail to cite previous work, so adherents of cybernetics think he did.

That's what I get, too. A "reward" is a subjective experience. If someone doesn't care about grades, then good grades will not be rewarding, and bad grades will not be punishment.

I think the core problem is our ignorance of psychology - we don't know how humans really work, what makes us tick, what are the 'incentives' that should be put in system design to move toward better science, and whether &#x2
