OpenDeep vs. other frameworks

OpenDeep is meant to bridge industry data scientists with cutting edge researchers

OpenDeep has many sibling frameworks intended to help deep learning. Each has their own strengths and weaknesses, but OpenDeep was created to address a specific need to make novel deep learning research available in industry. It is focused on bridging the gap as a 'black box factory', where you can easily create new algorithms for other people to use as black box implementations at scale.
