We were super honored and delighted to have Richard Socher (you.com) as a guest speaker at TU Dresden on May 11, 2023. Richard Socher has shared his view on state-of-the-art Natural Language Processing (NLP) research in the field of Machine Learning with us and joined a panel discussion with the local experts, Sunna Torge (TU Dresden, SCADS.AI, OpenGPT-X), Anna Poetsch (TU Dresden, CMCB/MSNZ), Oliver Guhr (Moderator, HTW Dresden) and Peter Steinbach (Moderator, Helmholtz-Zentrum Dresden-Rossendorf, Helmholtz.AI).
