description         Magenta: Music and Art Generation with Machine Intelligence

long_description    Magenta is a research project exploring the role\
                    of machine learning in the process of creating art\
                    and music. Primarily this involves developing new\
                    deep learning and reinforcement learning\
                    algorithms for generating songs, images, drawings,\
                    and other materials. But it's also an exploration\
                    in building smart tools and interfaces that allow\
                    artists and musicians to extend (not replace!)\
                    their processes using these models.
