“Machine Learning-assisted Animal Activity Sensing and Understanding”

Abstract. In this talk, our project related to AI-assisted systems for studies on animal navigation is presented. To elucidate the navigation ability of animals such as birds and mammals, biologists measure behaviors of the animals by attaching sensor loggers (e.g., GPS, acceleration, and camera loggers) to the animals, and then analyze the measurements to discover new findings or prove hypotheses. However, due to the restriction of the mass of the loggers, the running time of highly functional loggers (e.g., camera loggers) is limited, making it difficult to capture interesting animal behaviors. In addition, manual analysis of collected behavioral data (e.g., GPS trajectories) by biologists is burdensome because they need to analyze a large amount of behavioral data to acquire new discovery. In this talk, our AI-enabled bio-loggers to target potential interesting behaviors and explainable AI to support knowledge discovery from animal behavioral data are introduced.

“ A Neuro-symbolic Approach for IoT Applications”

Abstract. Automatically applying AI techniques to IoT applications is key given the exponential growth of data. This asks for an AI approach that can integrate methodical and domain knowledge which can be tackled by combining semantic models, machine learning and optimization. The talk presents such a neuro-symbolic approach which enables data scientists and domain experts alike to access insights trough Digital Twins. The benefits of the approach will be demonstrated on different real-world datasets ranging from Industry 4.0 over supply chains, to Covid 19.

Bio. Jörn Plönnigs is the IBM Research lead for “AI for Digital Twins”. His goal is to enable autonomous, highly scalable, and accessible IoT solutions for a sustainable future. He tackles it by developing AI solutions for IoT applications using machine learning and semantic models as well as natural interfaces. Prior to joining IBM in 2012, he was leading a junior research group at the Technical University Dresden, Germany, and the data analytics group of the Irish strategic research cluster ITOBO as Feodor-Lynen fellow of the Humboldt-Foundation. He holds a master in electrical engineering as well as a PhD and a Habilitation in computer science from Technical University Dresden. He is program committee member of several renowned international conferences and journals, founding editor of the IEEE IoT Magazine and board member of the IEEE IoT initiative.
