Trees look for splits by sorting each column.
Apparently you should take as many columns as possible and fill NAN in those rows where they are not used. If the model can handle NAN.
Or with something else: -INF, 0, +INF... so that all unused rows are on the same side when sorting.
This is more or less understandable. I'd like some kind of more creative approach or something. There are a lot of new tasks like working with video scenes of different length, etc.
What do you mean? Describe the problem
For example, I want to feed the classifier input price chunks not of a fixed length in bars (or in links of a zigzag pattern), but starting from some significant moment.

Recurrence nets are suitable, like many-to-many

The associative rules should be ok, i'll show an example
The data is in the form of a list , each row is a vector with observations of any length .
the code to search for patterns in the form of asociation rules
the rules
The algorithm looks for associations between elements regardless of their order...
There are order-aware algorithms, but they're greedy.
Or if you want more, there's a recommender system called recommenderlab, but I didn't get into it.
Recurrent networks are suitable, the many-to-many type
Thanks, I'll have a look.
Of course, I would like to have some kind of review text on the subject, with a description and comparison of approaches (there's no harm in wishing). In theory, there should be such a text somewhere, but so far I haven't found it.

I have only seen about input-output of variable length in such networks, and that is purely review, without going into it.
for word processing, translationsassociative rules should work, i will give you an example

Still, with us, order does matter. You can always for example get SB by mixing up the increments randomly.
I also remembered that I think you wrote here some time ago about sequential pattern mining and sequence alignment problem arising there. It also seems to be one of the methods of solving the problem. Although, belonging of sequences to one class does not necessarily mean their similarity.

Sparked one gold strategy from the marketplace ))
Capital curve in my tester.
threw it into tslab to get a better look
It looks like it's a good match.
I looked at the trades.
I looked at it as if it was a manual trader with extremely long sit and vague trading algorithm...
Forrest certainly could not identify anything, but it was interesting and informative )))
Recurrent networks are suitable, many-to-many type
Might be useful... I have a many-to-many without recurrence. And no convolutional layers. And I chose this model after I've analyzed the neural network mechanism. We're looking for a common denominator here, aren't we? Argue.
