Over the course of two days, we took a deep-dive into real-world industrial use-cases. #BAS21 addressed the ethical and societal challenges of human-machine interaction. The extensive international programme was filled with around 70 presentations, panels, and workshops from more than 120 speakers on two stages. This gave more than 3,000 participants the chance to learn and network with like-minded AI enthusiasts and Big Data experts. We are also grateful for the support of our 21 partners.
