hep_ml, python library for high energy physics

Main points

  • uniform classifiers - the classifiers with low correlation of predictions and mass (or some other variable, or even set of variables)
    • uBoost optimized implementation inside
    • UGradientBoosting (with different losses, specially FlatnessLoss is very interesting)
  • measures of uniformity (see hep_ml.metrics)
  • advanced losses for classification, regression and ranking for UGradientBoosting (see hep_ml.losses).
  • hep_ml.nnet - theano-based flexible neural networks
  • hep_ml.reweight - reweighting multidimensional distributions
    (multi here means 2, 3, 5 and more dimensions - see GBReweighter!)
  • hep_ml.splot - minimalistic sPlot-ting
  • hep_ml.speedup - building models for fast classification (Bonsai BDT)
  • sklearn-compatibility of estimators.

Installation

Basic installation:

pip install hep_ml

If you're new to python and never used pip, first install scikit-learn with these instructions.

To use latest development version, clone it and install with pip:

git clone https://github.com/arogozhnikov/hep_ml.git
cd hep_ml
sudo pip install .
