Description:

raredecay 2.1.0

raredecay
This package consists of several tools for the event selection of
particle decays, mostly built on machine learning techniques. It
contains:

a data-container holding data, weights, labels and more and
implemented root-to-python data conversion as well as plots and
KFold-data splitting
reweighting tools from the hep_ml-repository wrapped in a
KFolding structure and with metrics to evaluate the reweighting
quality
classifier optimization tools for hyper-parameters as well as
feature selection involving a backward-elimination
an output handler which makes it easy to add text as well as
figures into your code and automatically save them to a file
… and more

HowTo examples
To get an idea of the package, have a look at the howto notebooks: HTML
version or the
IPython
Notebooks

Minimal example
Want to test whether your reweighting did overfit? Use train_similar:
import raredecay as rd

mc_data = rd.data.HEPDataStorage(df, weights=*pd.Series weights*, target=0)
real_data = rd.data.HEPDataStorage(df, weights=*pd.Series weights*, target=1)

score = rd.score.train_similar(mc_data, real_data, old_mc_weights=1 *or whatever weights the mc had before*)

Getting started right now
If you want it the easy, fast way, have a look at the Ready-to-use
scripts.
All you need to do is to have a look at every “TODO” task and probably
change them. Then you can run the script without the need of coding at
all.

Setup and installation

PyPI
The package with all extras requires root_numpy as well as rootpy (and
therefore a ROOT installation with python-bindings) to be installed on
your system. If that is not the case, some functions won’t work.
Recommended installation (requires ROOT):
pip install raredecay[all] --process-dependency-links

Anaconda
Easiest way: use conda to install everything (except of the rep, which
has to be upgraded with pip for some functionalities)
conda install raredecay -c mayou36
To make sure you can convert ROOT-NTuples, use
pip install raredecay[root] # *use raredecay\[root\] in a zsh-console*
or, instead of root/additionally (comma separated) reweight or
reweight for the specific functionalities.
