Hello All,
I have a 12G dataset on which I want to run GradientBoostingRegressor. But
loading such a large dataset in memory is practically impossible. I can load it
in chunks and train the model in batch mode, but I don't see any partial_fit
method in gradient boosting.
Is there any other
Greetings scikit,
Last year I used delta idf and bm25 text weighting schemes with scikit
classifiers for an opinion classification task. Today I decided to clean
them and recheck them in order to propose it to scikit-learn text feature
extractors.
I only implemented delta idf and bm25 tf and
Hi Pavel,
First of all, this is an interesting subject, thanks for bringing it
up! I fear that it's too domain-specific to go very deep in this
direction.
That being said, and trying to interpret your benchmarks, it seems
that Delta-idf might actually be interesting.
Or, more generally, the idea

I don't know if this would be helpful to anybody or if this was already
discussed. That is why I am asking if it is worthy to be pull requested.

Yes! BM25 is high
I agree with Vlad that delta-IDF is interesting; but it is not well
supported by the community, and I'm not sure it is worth including ... yet.
As Lars points out (and as you suggest), there are other ways to supervise
feature weighting. I agree this has to be a separate transformer
Hey there,
Interesting discussion. Of course, the danger here is that it might be
borderline for the scope of scikit-learn. In case somebody is going to
docstringdo a PR on these topics, I would advise to work on the docstring
and narrative documentation to explain well why this can be useful
