Re: Stupid question of the day

Looks spoiled, almost full MC.. that's pretty far from minimal spanning.  You can still save it, but it'll cost you log log log n time.

Re: Stupid question of the day

tt is a weeping willow. It is suffering from watermark sickness. It is rust in peace. It was planted by the previous owner to the memory of his daughter who fell into the adjoining waterway and drowned. That's so sad! But on the literal bright side, the recommended treatment is felling and burning ...

Re: Those crazeeeee Dutch

Giro, NMB. it's all ING now. I'm there too (and Rabo, Triodos). When I was a option trader at Beurplein I spend a couple of year in the ABN-AMRO pit. ABN-AMRO options was the 2nd most actively traded options market in the world at that time because of a couple of crazy ego traders who tries to burry...

Re: Does Cauchy sequence ever occur in the real world or is it all the minds of mathematicians?

BTW I am trying to get my head around DE for backpropagation by using it instead of *GD. Correct me if I am wrong, but the jury is still out on the applicability of GD. Lets start at the beginning: what variable specify the loss functions, and what is the goal of minimizing a loss function? One of ...

Re: Does Cauchy sequence ever occur in the real world or is it all the minds of mathematicians?

"outdated pseudophilosophical banter"? What you need is a water massage! Theory-ladenness is a very profound concept (yes, another concept!) That concept was discussed by physicists half a century ago, if I'm precise. The problem is you first need to know the subject to which you apply it. A lot se...

Re: Does Cauchy sequence ever occur in the real world or is it all the minds of mathematicians?

I think this trying to give you an friendly opportunity to let it dawn?  He knows the answers, everything DE is theory laden by definition. You can't proof that your model of reality *is* reality.  (and you can't present a counter example to a "are there X?" questions, but that's just simple 2nd ord...

Re: Does Cauchy sequence ever occur in the real world or is it all the minds of mathematicians?

The distance from reality to concept >> distance from concept to realty.  This is "theory-laden" too. What distance metric, and what space are we going to position both "the concept" and "reality"? Do we have a final model of reality as well as how concepts are represented in our brain? Does "a bra...

It's only a model and that is a product of the mind.
That's the main point of this topic.

Re: Trump -- the last 100 days

I knew something was wrong with this White House, but had perhaps not put my finger right on the root cause: not enough Kardashians! In the name of more photo ops for Trump, this has now been remedied.
From what I've heard Kim is visiting Donald to discuss law reforms.

What was *that*??! Kraftwerk? Joaquin Phoenix or leonardo di Caprisun playing Howard Hughes?
I think leonardo di Caprisun playing Howard Hughes
Time for some eccentric Moloko then!
