It's a bit difficult to explain the visualization without pictures, but I'll give it a shot. The transpose is really about converting the matrix to operate on a different vector space, namely, the dual space. In particular, the du

I agree that having possible examples in mind is a great way to learn mathematics. There are whole books on useful counterexamples, e.g. https://www.amazon.com/Counterexamples-Analysis-Dover-Books-... These counterexamples

I'm not supporting the GP's viewpoint, but I think their point is that we don't have enough information to attribute warming specifically in the Arctic to human causes. I don't know very much about the subject, but given

Consider the following (traditional) program: x = raw_input() x *= 2 assert x >= 10 Now we can ask the question: "Assuming the assertion passed, what can we say about x?" In this simple example, we know that x >=

How do you know it's the same cat? A neural network needs to be explicitly told, "these are all the same cat".

The GP is saying that rational expectations is used not because it's simple, but because it makes the weakest assumptions about human behavior. However, I'm not sure this is entirely accurate since if some agents deviate from the

The standard approach to detecting signal lights is to have a database of GPS positions of the signals, along with rough location in the camera where the signal is expected to occur [1]. Then, when the car nears the signal, it locates the s

Word has its own version control built in, which works pretty well. You can see all revisions, and step through and accept/reject. You can also do diff of two documents.

I think one of the biggest challenges in moving from 1v1 to 5v5 is the substantially increased possibility of creative strategies. In a 1v1, there isn't that much room for innovation, making it a perfect target for existing AI techniqu

My understanding is that in a full match, AIs still have no hope against humans, since even though they can crush humans at micro, their macro is still abysmal [1]. I'm not aware of a match where any AI has beat a pro human player at S

Do you have a citation? As far as I know, existing AIs do not stand much of a chance again humans [1]. My understanding is that even if AIs can beat humans is small skirmishes due to superior micro, they lose so badly at macro that it simpl

Unless I am missing standing, the goal is only to produce a new interpretation of quantum mechanics. That is, the predicted physics do not change, only the formulation of the theory. Therefore, anything possible under this formulation is al

The attack you suggest is ruled out by differential privacy. The precise guarantee is a bit complicated. The first thing to note is that the output of a differentially private mechanism must be random. Then, the guarantee is that Pr[output]

Just because people collaborate from all over the planet to make the pencil, doesn't mean that's the way it has to be. This kind of collaboration simply enables economics of scale to kick in (and possibly improve quality as well).
