The conference is organized as the culminating event of the "Signatures for Images" (SFI@CAS) project at the Centre for Advanced Studies (CAS) in Oslo. 

Over the last decade, the concept of path signature, viewed as a one-parameter object formed by iterated integrals along a path, has gained significant traction, particularly in data science applications. Its success lies in its ability to furnish features that effectively describe the path. This effectiveness is attributed to the linear-time computability of the path signature, facilitated by Chen’s identity. Expanding this concept to surfaces necessitates an augmentation of parameters, entailing the consideration of iterated integrals along surfaces. The conference seeks to unite experts in discussions surrounding the latest advancements on path and surface signatures. It aims to explore emerging trends and applications within these domains, fostering collaborations and knowledge exchange among researchers.
