There aren't many links (sadly, most of them aren't github users), but I
hope it might help someone here! Also, feel free to add any
cathegory/repository you are using!

There are feature selection algorithms based on Evolutionary Algorithms,
so, despite the exponential space of search, you can fix a number of
evaluations.
Experimentally, this approach have found optimal solutions on
Instace/Feature/Classifier selection, without exploring the whole search
space.

Mario, as I said, the correct would be:
- AUC = (1 + TP_rate - FP_rate) / 2
But you are also right, that is another evaluation metric stated in those
references
could
change to this approach!
Again, thanks!

Hi Olivier,
I solved this issue, but talking to some people in the maillist,
they adviced me to start
Also, is there any plans to add a transform(X, y, axis=1) in the pipe?
Is anybody working on that?
Thanks,

Hi Nicholas,
I have some works on outlier detection, let me know how can I help, once
you start this project.
Thanks,

orthogonal set of algorithms (which may not be seminal enough for
inclusion anyway) seems unlikely at present. I suggest you make the
instance reduction directory a separate repository, and invite comment
there.
Cheers,

Given that the technique seems to be KNN-focused, it could be
incorporated as an extension to the KNN classifier/regressor classes, by
providing an option to reduce the population when fitting, rather than a
set of separate estimators.

Hi There,
I am working on Instance Reduction (noise removal) on sklearn as my first
contribution (hopefully) and I know a SMOTE implementation would be very
helpful.
Checkout Garcia et all Evolutionary Based IR for imbalanced Datasets. It
concludes that SMOTE oversampling is very helpful for
, but I do not think that's the case.
Thanks,
