Variational Learning is Effective for Large Deep Networks

1 code implementation27 Feb 2024 Yuesong Shen, Nico Daheim, Bai Cong, Peter Nickl, Gian Maria Marconi, Clement Bazan, Rio Yokota, Iryna Gurevych, Daniel Cremers, Mohammad Emtiyaz Khan, Thomas Möllenhoff

We give extensive empirical evidence against the common belief that variational learning is ineffective for large neural networks.

Model Merging by Uncertainty-Based Gradient Matching

no code implementations19 Oct 2023 Nico Daheim, Thomas Möllenhoff, Edoardo Maria Ponti, Iryna Gurevych, Mohammad Emtiyaz Khan

Models trained on different datasets can be merged by a weighted-averaging of their parameters, but why does it work and when can it fail?

Uncertainty in Natural Language Generation: From Theory to Applications

no code implementations28 Jul 2023 Joris Baan, Nico Daheim, Evgenia Ilia, Dennis Ulmer, Haau-Sing Li, Raquel Fernández, Barbara Plank, Rico Sennrich, Chrysoula Zerva, Wilker Aziz

Recent advances of powerful Language Models have allowed Natural Language Generation (NLG) to emerge as an important technology that can not only perform traditional tasks like summarisation or translation, but also serve as a natural language interface to a variety of applications.

MathDial: A Dialogue Tutoring Dataset with Rich Pedagogical Properties Grounded in Math Reasoning Problems

1 code implementation23 May 2023 Jakub Macina, Nico Daheim, Sankalan Pal Chowdhury, Tanmay Sinha, Manu Kapur, Iryna Gurevych, Mrinmaya Sachan

While automatic dialogue tutors hold great potential in making education personalized and more accessible, research on such systems has been hampered by a lack of sufficiently large and high-quality datasets.

Task-oriented Document-Grounded Dialog Systems by HLTPR@RWTH for DSTC9 and DSTC10

no code implementations14 Apr 2023 David Thulke, Nico Daheim, Christian Dugast, Hermann Ney

This paper summarizes our contributions to the document-grounded dialog tasks at the 9th and 10th Dialog System Technology Challenges (DSTC9 and DSTC10).

Elastic Weight Removal for Faithful and Abstractive Dialogue Generation

1 code implementation30 Mar 2023 Nico Daheim, Nouha Dziri, Mrinmaya Sachan, Iryna Gurevych, Edoardo M. Ponti

We evaluate our method -- using different variants of Flan-T5 as a backbone language model -- on multiple datasets for information-seeking dialogue generation and compare our method with state-of-the-art techniques for faithfulness, such as CTRL, Quark, DExperts, and Noisy Channel reranking.

Opportunities and Challenges in Neural Dialog Tutoring

1 code implementation24 Jan 2023 Jakub Macina, Nico Daheim, Lingzhi Wang, Tanmay Sinha, Manu Kapur, Iryna Gurevych, Mrinmaya Sachan

Designing dialog tutors has been challenging as it involves modeling the diverse and complex pedagogical strategies employed by human tutors.

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.

Adapting Document-Grounded Dialog Systems to Spoken Conversations using Data Augmentation and a Noisy Channel Model

1 code implementation16 Dec 2021 David Thulke, Nico Daheim, Christian Dugast, Hermann Ney

This paper summarizes our submission to Task 2 of the second track of the 10th Dialog System Technology Challenge (DSTC10) "Knowledge-grounded Task-oriented Dialogue Modeling on Spoken Conversations".

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.
