Crino: a neural-network library based on Theano

Crino is an open-source Python library aimed at building and training artificial neural-networks. It has been developed on top of Theano, by researchers from the LITIS laboratory. It helps scientists and/or programmers to design neural-network architectures adapted to their needs, using a modular framework inspired by Torch. Our library also provides vanilla implementations, and learning algorithms, for these architectures :

• auto-encoders (AE)
• multi-layer perceptrons (MLP)
• deep neural networks (DNN)
• input-output deep architectures (IODA)

IODA is an extension of DNN architectures, which is useful in cases where both input and output spaces are high-dimensional, and where there are strong interdependences between output labels. The input and output layers of a IODA are initialized with an unsupervised pre-training step, based on the stacked auto-encoder strategy, commonly used in DNN training algorithms. Then, the backpropagation algorithm performs the final supervised learning step.

Crino and IODA are research topics of the Deep in Normandy research program, which is a NVIDIA GPU Research Center.
