Shadow is a PyTorch based library for semi-supervised machine learning. The shadow python 3 package includes implementations of Virtual Adversarial Training, Mean Teacher, and Exponential Averaging Adversarial Training. Semi-supervised learning enables training a model (gold dashed line) from both labeled (red and blue) and unlabeled (grey) data, and is typically used in contexts in which labels are expensive to obtain but unlabeled examples are plentiful.

Shadow can by installed directly from pypi as:

pip install shadow-ssml
