Traits (predictors, variables, functions, features)are individual measurable properties or characteristics of an observed phenomenon. For example, quotes, day of the week, time of day, etc. In our case, as a rule, these are time series .
There is no need to redefine established concepts unnecessarily. This leads to confusion and misunderstanding of the purpose of the discussion. In your case: We are talking about an arbitrary length of a vector of consecutive values of a predictor(trait, function, feature, etc.).Hence the question about columns.
More carefully.
I understand that we need to distinguish more carefully between the length of columns and the number of columns. The former is equivalent to the number of rows, the latter to the length of rows).
Although, with different length of rows the concept of columns is somewhat blurred - instead of a rectangular table (dataframe) the concept of a list of rows becomes relevant.
PS. I also suggested for simplicity to limit ourselves to the case when all signs are only prices on the previous section (with different length)

That's what a total gypsy liar says, which you are. Don't flatter yourself.
You can tell who is a liar by the number of productive posts. All your posts are not backed up by research.
I can only respect people who speak on the matter and back up their words with research.
I have great respect for Aleksey Vyazmikin and others. He bravely brings out ideas for discussion and shows the result.
Now you know who you really are? Maksimka.)))))

You can respect anyone, it won't change your status.

I see what you're good at.)
But you're weak when it comes to understanding markets. That's what we're talking about.
I see what you're good at:)
But in understanding markets, you're weak. That's what we're talking about.
Well you do realise that you lack the natural intelligence to make such judgements
After such a judgement, I am silent.)))))
After such a conclusion, I am silent.)))))
