Hello. I am a machine learning enthusiast. Recently I got interested in NLP and I found attention model interesting.

I was reading https://arxiv.org/pdf/1409.0473.pdf

and I couldn’t find how to compute Cz, Cr, and C.

You can find them in the paper, Appendix A where they explain how to compute update gates and reset gates.

I have searched on google but seems like people don’t mention how to compute them.

​

1. How to compute Cz, Cr, and C in Bahdanau attention model?
2. Where should I ask these questions? ( I am new to Machine learning and don’t have anyone to ask in person)
3. Am I focus on too much detail? Should I just use libraries which has pre-built attention models? Actually I am working on a simple chat-bot project.
