skl-groups is a package to perform machine learning on sets (or "groups") of
features in Python. It extends the scikit-learn <http://scikit-learn.org>
_
library with support for either transforming sets into feature vectors that
can be operated on with standard scikit-learn constructs or obtaining
pairwise similarity/etc matrices that can be turned into kernels for use in
scikit-learn.
For an introduction to the package, why you might want to use it, and how to
do so, check out
the documentation <https://dougalsutherland.github.io/skl-groups/>
_.
skl-groups is still in fairly early development.
The precursor package, py-sdm <https://github.com/dougalsutherland/py-sdm/>
_,
is still somewhat easier to use for some tasks (though it has less functionality
and less documentation); skl-groups will hopefully match it in the next few weeks.
Feel free to get in touch (dsutherl@cs.cmu.edu) if you're interested.
Full instructions are
in the documentation <https://dougalsutherland.github.io/skl-groups/installation.html>
_,
but the short version is to do::
$ conda install -c dougal -c r skl-groups
if you use conda, or::
$ pip install skl-groups
if not. If you pip install and want to use the kNN divergence estimator,
you'll need to install either
cyflann <https://github.com/dougalsutherland/cyflann/>
_
or the regular pyflann bindings to FLANN,
and you'll want a version of FLANN with OpenMP support.
A much faster version of the kNN estimator is enabled by the skl-groups-accel package, which you can get via::
$ pip install skl-groups-accel
It requires cyflann and a working C compiler with OpenMP support (i.e. gcc, not clang).
