Yes, I do not really remember, I remember it changed something, but not so much... But this is a completely different picture

because the exponential growth in the log scale looks like a linear one)

 
Maxim Dmitrievsky:

because the exponential growth in the log scale looks like a linear one)

and it should have a better effect on generalization, in theory

 
mytarmailS:

Regarding the generation approach itself, a criticism from me)

When you create data and go through models looking for a model that will work on "new data" , do you understand that it's a fitting ? do you realize that it's a fitting?

Since this "new data" is involved in the choice of the model, it is not"new data"... it's not very obvious but it's true !

Maxim Dmitrievsky:

on the 3rd one i checked, yeah.

Continuing the theme.... dug up the old code of those GMMs of yours.

found 4 good models that are on the plus side of "like new data"

GMM model was generated on 500 points test on 15k points



And here they are, on really new data (third sample)




What is interesting, if we reverse the position opening signals for the last two (sinking) models, then they start to earn very well with the commission taken into account

 

And I slowly continue to experiment with training neural networks with fitness function ....

I came up with this way of describing the utility function (fitness function) , instead of teaching the network to get maximum profit I tried to teach the network to "maximally beautiful graph of income"

What is "maximally beautiful income graph"? I put it as coefficient of correlation of linearly increasing line and yield graph

here is the balance on the triple data, the commission is taken into account

correlation coefficient 0.9947626 almost unity)) even on the graph it is clear that it is like a ruler))


Blue shows balance on a test sample of 800 points of 5 min euro


And this is how balance looks like on a test sample of 5k points

nice))

cool )))

did you expect something else? )

 
mytarmailS:

Well, it should have a better effect on generalization, in theory

it doesn't owe anyone anything.

 
Maxim Dmitrievsky:

You were expecting something else? )

I, on the contrary, am satisfied, teaching to max. profits is, for example, a lottery on the test, and here at least a small island of stability

800 points on a 5 minute is not too little
 
Maxim Dmitrievsky:

But the reverse is more difficult. With MO on logic. Almost impossible, you can only approximate

IO can only be broken by another stronger IO

Reverse grid is an interesting topic.

Put noise on the inputs. Get the spectrum at the output. Build a filter on it.

Then it will turn out that it is possible to get the same result with a combination of bags.

Then we will come to random convolution packet (I forget its name).

And then fantasy will come to an end...

Fade. Darkness. The Factory.

funny ))

Same thing with pair trading, looking for nice spread and it runs away with AOS.

There the pattern ends, no matter how you teach it. For this you need to semplicate other examples, what was talked about yesterday
