About me

Hello there! I'm Silvia Terragni and I'm a Senior NLP Research Engineer at Telepathy Labs, previously a Ph.D. Student at the University of Milano-Bicocca. My research as a PhD Student focused on Topic Models and NLP. My work appeared in the top-ranked NLP venues (ACL, EACL, EMNLP) and Q1 Journals in Artificial Intelligence. I usually open-sourced the code I produced during my PhD. These are my main projects:
  • I collaborated with MilaNLP Lab on the combination of neural topic models and language models' representations. I am a maintainer and contributor of the python package contextualized-topic-models.
  • I designed and developed OCTIS, an open-source and comprehensive python framework for training Topic Models. It uses hyper-parameter Bayesian Optimization to ensure a fairer comparison between the models.


If you want to know more about my projects and stuff, here you can currently find a small selection of my projects, my my talks and my publications . Otherwise we can get in touch on Twitter or by email :)
