They don't use huggingface, but some of the modern approaches for topic modeling use variational auto-encoders, see:

Open-SESAME (2017): https://arxiv.org/abs/1706.09528 / https://github.com/swabhs/open-sesame

VAMPIRE (2019): https://arxiv.org/abs/1906.02242 / https://github.com/allenai/vampire



Thanks! I hadn’t seen VAMPIRE! So stoked to see a new approach to topic modeling. SVD etc are very much a local max
