Artificial Bandwidth-Extension with Sum-Product Networks
This package performs training and inference for ABE, using an HMM/SPN-model as described in . It is based on Matlab, but calls C++ binaries for training and inference of SPNs. The core routine for training is the Poon & Domingos algorithm for training SPNs , which was ported to C++ here.
