December 2019: Together with Samson Abramsky and Alessandra Palmigiano we organised a Lorentz Centre workshop on Logic and Structures in Computer Science and Beyond, see here for the programme and description. We had a very nice combination of long and short impromptu talks, as well as very fruitful discussion and breakout sessions. I learnt quite a lot about contextually and Fock spaces.
December, I gave the Lunchtime lecture for the Lorentz Centre’s Faculty of Science “This weeks discovery”, with title “Understanding natural language: logic or statistics, which one is more important?”.
September 2019: I gave a talk in the Theoretical Neurobiology research group of the centre for Human NeuroImaging. The title of the talk was “Convergence in Dialogue via Incremental Vector Representations” and the material was based on our SemDial 2018 paper with Matt Purver, Ruth Kempson, and Julian Hough. Based on some recent joint work, I argued that a principle similar to the principle of free energy used by Prof. Karl Friston in the brain, can be applied to linguistic data exchanged by humans to achieve a degree of synchrony in dialogue, by measuring the decreasing rate of the distances between utterances vectors of the dialogue.
