Espnet: [Info] C++ backend

Created on 4 Jan 2019 · 3Comments · Source: espnet/espnet

As a proof of concept, I'm making a C++ backend of ESPnet during my winter vacation. It can read ESPnet's dump features (json/scp) and train neural networks. Here is tiny AN4 example. Have fun.

I found that current C++ backend is little bit faster than Python in training. (base transformer with minibatch 16)

Python backend 5.0 iter/sec
C++ backend 6.5 iter/sec

30% speed up!
