Our experience of the world is multimodal and understanding multimodal data streams (complex sequences of data from different sources), is a key challenge of rough path theory and more generally for data science. This workshop therefore aims to increase awareness of the research and applications being undertaken by the DataSıg team. The Programme seeks to further develop signature-based mathematical tools for dealing with complex streamed data, and connect with partners who have the capability and the challenges to benefit from and achieve significant outcomes with the methodology.
