dtw, spectral analysis... a bunch...
i managed to create an algorithm that can see the same patterns regardless of their magnitude, i.e. the algorithm looks at one chart and sees the pattern on both the 1-minute and weekly charts, looking at only one chart, and it can really make predictions, but there is still a lot of work
i've started to read about dtw, but i don't know how to apply it to finance lines and what for i need it) but it may be an interesting topic
i started to read something about dtw, but did not understand how to apply it to fin rows and why i need it) but the topic is interesting, i guess
voice and music files are compressed using dtw and they are BP too
;)
voice and music files are compressed with dtw, and they are also BP
;)
but what is the point of compressing dtw :)
But why compress fin. vr :)
Well, I have already studied this topic, in my own words, it's about this:
here in general, the value ofdtw - this is the correct algorithm for compressing BP - just BP, and not just any and whatever the data
well, if we know how to compress data correctly - do we get packages? images? - or let it be data patterns - this is exactly the data patterns which allow you to create speech recognition algorithms
this is how i seedtw being used
In principle it is possible to apply dtwto financial BP, imho if there is no data loss after conversion (i.e. reverse conversion is possible), then it makes sense to try to apply it to financial BP, as they say, but what if?

Well, it will be possible to do some digging sometime later, yes. To retrieve the same patterns from returns mb
On the other hand, why bother, if there is a neural networkon the other hand there is no need, if there is a neural network
i don't know, i abandoned the study of all this, it's interesting, but imho, there should and there are easier ways to understand what's what in the market
about NS, you know that data processing is more important than config or type of NS, imho, dtw is the correct processing of BP ( when processing exactly BP!!! ) it's the sequence of data that matters!
about the same dtw in voice processing - the sequence / alternation of letters is important ? ;)
UPD:
if you feed just a sliding window of BP data (bars) to the NS during training, then imho, it is an illusion that through the inputs of the NS - exactly as we drew 1,2,3...N input, the NS will perceive that the data are fed sequentially as we want, inside all inputs will be mixed up, imho, it will not be a sliding window for the NS

I'm not knowledgeable in these matters, as far as I know recurrent and ultra-precise neural networks have been used for a long time. For example Google's seq2seq algorithm. Would not dtw look pale on that background, I would not want to squeeze my knuckles in a chair for unnecessary time :)
I read about recurrent and ultra-precise, well, as if yes, but all the examples are as always on the recognition of pictures, and there start tricks with palette compression like to produce
I don't know, sound waves are closer to BP than pictures - also not stationary, and pictures seem to lose more by compressing information during processing than try to recover - it's like the NS learns faster and better

NLP and seq2seq, those are for speech sounds and stuff.
I haven't heard about them at all, although I've read a lot of material! I'll look it up tomorrow, thanks.
