Paper 2: vONTSS: vMF based semi-supervised neural topic modeling with optimal transport Accepted by ACL 2023 as findings. It leverages vMF as prior for topic modeling. It is relevant to NTM with Different Structure / NTMs with Various Priors Paper link: https://aclanthology.org/2023.findings-acl.271/ Code link: https://github.com/xuweijieshuai/Neural-Topic-Modeling-vmf
