 DeepLearning.scala is heavily inspired by my colleague [@MarisaKirisame](https://github.com/MarisaKirisame). Originally, we worked together on a prototype of a deep learning framework, and eventually split our work into this project and [DeepDarkFantasy](https://github.com/ThoughtWorksInc/DeepDarkFantasy).
