Students I co-supervise and co-supervised:


2020/07/25: We got two papers on neural text-to-speech accepted to Interspeech, both are available on arXiv: Tomáš Nekvinda's One Model, Many Languages: Meta-learning for Multilingual Text-to-Speech and Jan Vainer's SpeedySpeech: Efficient Neural Speech Synthesis.

2020/07/01: Me & Vojtěch started working on a joint project METOD with Agnostix, investigating dialogue management modelling and visualizations, supported by the City of Prague.

2020/05/26: We (Jindřich Libovický, Zdeněk Kasner, Jindřich Helcl & me) took part in the STAPLE/Duolingo translation & paraphrasing WNGT shared task. Our report is now in the ACL anthology.

2020/04/06: Our paper “Fact-based Content Weighting for Evaluating Abstractive Summarisation” (by Xinnuo Xu, me, Jingiy Li, Yannis Konstas & Verena Rieser) was accepted for ACL. You can read the paper in the ACL anthology.

2020/04/01: Our grant project THEaiTRE for automatically generating theatre plays was accepted by the Czech Technical Agency (and actually got the highest ranking of all submissions)! We plan to have a theatre play performed in January 2021, for the 100th anniversary of Karel Čapek's R.U.R.

2020/03/23: Verena Rieser and I were guests at the NLP Highlights podcast, and we talked about data-to-text generation. You can listen to the podcast on Soundcloud.

2020/03/03: I gave a short talk at the Czechbots chatbot meetup. You can find the slides here.

2020/02/18: Our undergrad Dialogue systems course started its 2020 run – lecture slides will appear on the course webpage.

2019/10/31: I presented 3 papers at INLG 2019: Neural Generation for Czech: Data and Baselines (work with Filip Jurčíček), Semantic Noise Matters for Neural Natural Language Generation (work with Dave Howcroft and Verena Rieser), and Automatic Quality Estimation for Natural Language Generation: Ranting (Jointly Rating and Ranking) (work with Karin Sevegnani, Ioannis Konstas and Verena Rieser).

2019/10/03: We started teaching a new course on Statistical dialogue systems – lecture slides will appear on the course webpage.

2019/09/13: Our paper User evaluation of a multi-dimensional statistical dialogue system (with Simon Keizer, Xingkun Liu and Verena Rieser) was presented at SIGDIAL in Stockholm and is now online on arXiv.

2019/07/10: Our paper analyzing the E2E NLG Challenge results is now published in Computer Speech and Language and available online as open access.
