МОСКВА, 17 дек — РИА Новости. Ученые выяснили, что нейронная система обработки визуальной информации намного сложнее, чем считалось ранее. Эксперимент на мышах показал, что лишь небольшая часть нейронов зрительной коры мозга ведет себя так, как предсказывает классическая модель. Результаты исследования опубликованы в журнале Nature...
 
 
Maxim Dmitrievsky:

when Y changes in proportion to X, i.e. there is a linear dependence + cycles + noise, it makes no difference which way both razrevulki go, even in different directions

Well, there are not enough observations, it would be 1000 times more. Or to assess the fundamental law behind the curves, how much it is consistent.

That's it, I'm off the forum. Happy New Year!

How does this help us?

 
Maxim Dmitrievsky:

Do you know why the visual cortex is in the back of the head and not closer to the eyes?

Evolution has decided so.

 
Anatolii Zainchkovskii:
Boris, a synthetic is just a sum of financial series. The only thing you can do on a synthetic is to narrow the variance indefinitely. Hence, I suggest to continue observing the diverging curves of the original series instead of synthetics. You will see the same picture, with the same expanding curves.Alas, I can't tell you how to trade this expanding pattern. But I can suggest that if some part of the curvatures began to change the directional vector, most likely some other part should also change its vector of directionality.
It will be more interesting to find out when this expanding cloud of curvulus has a strong offset from the center, then it will be possible to collect statistics and try to reveal something useful. But this is not MO, and therefore I apologize for throwing in information off-topic.

Well, the dispersion can be narrowed down as much as you want.

It is even possible to get the synthetics to sometimes meet the "stationary process" part of the definition, but what's the use?

Here's one of the curves

 
Boris:

How does that help us?

Well, cointegration.

 
Aleksey Vyazmikin:

Evolution decided that.

Yes, amphibians had balls on top of the head, then they moved forward and the brain stayed there

 
Maxim Dmitrievsky:

Yes, amphibians had balls on top of the head, then they moved forward and the brain stayed there.

It is possible, but all this is written with holes in the water - until the evolutionary genetic material is thoroughly studied, it is all a hypothesis.

 
Aleksey Vyazmikin:

Perhaps, but it's all written with holes in the water - until the evolutionary genetic material is thoroughly studied - it's all a hypothesis.

It's all been studied for a long time.

fish came as amphibians, some evolved into mammals and then you evolved.
