"defn":"MozartNet is a sequence to sequence deep neural network trained on the music of Wolfgang Amadeus Mozart. It is used to generate music for a piano transcription in a completely unsupervised fashion. MozartNet is an instance of a more general family of networks known as 'autoregressive networks', and is trained on a synthetic dataset of about 1 million short sequences of piano notes. The network is a two layer LSTM and is trained with L2 regularization to minimize the total number of parameters. MozartNet is one of the most widely used and best-performing autoregressive networks, and is often cited as an example of using a neural network for the purpose of learning the structure of music.",
