Deep Jointly-Informed Neural Networks

DJINN: Deep jointly-informed neural networks

DJINN is an easy-to-use algorithm for training deep neural networks on supervised regression tasks. For additional information, refer to the paper "Deep neural network initialization with decision trees", cited below.

Getting Started

DJINN requires TensorFlow (v1.0.1 or later) and
scikit-learn (v0.18 or later is recommended). DJINN also uses numpy, matplotlib, and cPickle. Sphinx is required to view the html documentation.

Note that the sklearn version used when training a DJINN model must be the same version used when reloading/evaluating the saved model.

To use DJINN, clone the repo and install:

$ git clone https://github.com/LLNL/DJINN.git
$ cd DJINN
$ pip install -r requirements.txt
$ pip install .

Try it out! Examples for training DJINN models are included in the tests folder.

-python djinn_example.py (single output)

-python djinn_multiout_example.py (multiple outputs)

For Mac users with Anaconda installs, it might be necessary to manually install matplotlib via pip:

$ pip install matplotlib

If matplotlib will not import, try running "pythonw", for example:

$ pythonw djinn_example.py
