onelearn: Online learning in Python

Documentation | Reproduce experiments |

onelearn stands for ONE-shot LEARNning. It is a small python package for online learning with Python. It provides :

  • online (or one-shot) learning algorithms: each sample is processed once, only a single pass is performed on the data
  • including multi-class classification and regression algorithms
  • For now, only ensemble methods, namely Random Forests


The easiest way to install onelearn is using pip

pip install onelearn

But you can also use the latest development from github directly with

pip install git+
