Re: Universal Approximation theorem

That was "less than useful", love.
It's what Wiki says, so it must be right..
Or was it a rhetorical question on your part?  :shock:

Re: Universal Approximation theorem

People trying to communicate but not speaking the same language .... This thread is going nowhere. Correct. Too bad, maybe a little bit of good will could help ? For me the topic is good, if I understood it well : "dig in Cybenko Theorem to turn it into a practical tool". This could really help the...

Re: Universal Approximation theorem

There is a difference between numerical optimisation and statistical learning algorithms, which I think you and Cuch are missing. The goal of the first is, given f(x), find x0 = argmin x f(x). The goal of the latter is given a training set, find model parameters which lead to the expected error rat...

Re: Universal Approximation theorem

If you're talking about UAT, then what does GD have to do with it? Oh dear.  UAT talks about activation functon AF used in GD Ergo  UAT related to GD. AF is a confounder here. Another less than useful 1-liner.  Achtung: I'm writing the requirements. Don't change the problem. The properties of AF de...

Re: Universal Approximation theorem

I thought we were talking about approximation theory and numerical approximation. Are they contingent on  statistical learning algorithms in some way?> I would be inclined to say they are weakly coupled or not contingent on each other Maybe give a concrete example to help us understand your thesis. ...

Re: All Things DUP (Democratic Unionist)

I can't speak for them, but I had not. It looks like a very interesting place! And to add a language connection (which I'm guessing is real), the Norwegian word for puffin is "lundefugl", i.e. bird of Lundy.  Lundy is reviled in Ulster loyalism    to this day as a traitor and is burned in effigy du...

Re: UK and the EU: In or out?

I suppose the English never forgave the Dutch for the naval attack on the Medway.

The English lost that war.
