%description
A simple user-friendly library based on the 'python' module 'reservoirpy'.
It provides a flexible interface to implement efficient Reservoir
Computing (RC) architectures with a particular focus on Echo State
Networks (ESN). Some of its features are: offline and online training,
parallel implementation, sparse matrix computation, fast spectral
initialization, advanced learning rules (e.g. Intrinsic Plasticity) etc.
It also makes possible to easily create complex architectures with
multiple reservoirs (e.g. deep reservoirs), readouts, and complex feedback
loops. Moreover, graphical tools are included to easily explore
hyperparameters. Finally, it includes several tutorials exploring time
series forecasting, classification and hyperparameter tuning. For more
information about 'reservoirpy', please see Trouvain et al. (2020)
<doi:10.1007/978-3-030-61616-8_40>. This package was developed in the
framework of the University of Bordeaux’s IdEx "Investments for the
Future" program / RRI PHDS.
