neural_filters is a PyTorch toolbox implementing linear IIR filters as recurrent neural units
This package implements Neural Filters related to the following paper:
"François Marelli, Bastian Schnell, Hervé Bourlard, Thierry Dutoit, and Philip N. Garner. An end-to-end network to synthesize intonation using a generalized command response model. In Proceedings of the IEEE International Conference on Acoustics, Speech and Signal Processing, Brighton, UK, May 2019"
Neural Filters are linear IIR filters integrated in the PyTorch framework, which can be interfaced with neural networks and trained by gradient descent.
