ClimateGPT: Towards AI Synthesizing Interdisciplinary Research on Climate Change

1 code implementation17 Jan 2024 David Thulke, Yingbo Gao, Petrus Pelser, Rein Brune, Rricha Jalota, Floris Fok, Michael Ramos, Ian van Wyk, Abdallah Nasir, Hayden Goldstein, Taylor Tragemann, Katie Nguyen, Ariana Fowler, Andrew Stanco, Jon Gabriel, Jordan Taylor, Dean Moro, Evgenii Tsymbalov, Juliette de Waal, Evgeny Matusov, Mudar Yaghi, Mohammad Shihadah, Hermann Ney, Christian Dugast, Jonathan Dotan, Daniel Erasmus

To increase the accessibility of our model to non-English speakers, we propose to make use of cascaded machine translation and show that this approach can perform comparably to natively multilingual models while being easier to scale to a large number of languages.

Controllable Factuality in Document-Grounded Dialog Systems Using a Noisy Channel Model

1 code implementation31 Oct 2022 Nico Daheim, David Thulke, Christian Dugast, Hermann Ney

In this work, we present a model for document-grounded response generation in dialog that is decomposed into two components according to Bayes theorem.

Cascaded Span Extraction and Response Generation for Document-Grounded Dialog

1 code implementation ACL (dialdoc) 2021 Nico Daheim, David Thulke, Christian Dugast, Hermann Ney

For the second subtask, we use a cascaded model which grounds the response prediction on the predicted span instead of the full document.
