I want to use a recurrent convolutional neural network for language identification, I am planning to feed mel-spectrograms to it as an input. This paper used RCNN but their implementation is mostly in CNTK, but I would prefer python libraries such as keras or tensorflow. Is there a reliable implementation of it. I have found any implementations of RCNN but they are all handling object detection problem and none of those provide a RCL layer to used in a network. I found this github-repo but it seems to be incomplete, or is it not?
