Rough path signature

WebThe signature is then computed by calling stream2sig(path_data, truncation_degree), after formatting path_data as a numpy.array. The degree d is roughly defined as the maximal order to which iterated integration is performed. The signature can then be represented as a linear combination of words of length at most d. WebJul 9, 2024 · At the core of rough path theory is the so-called signature transform which, while being simple to define, has rich mathematical properties bringing in aspects of analysis, geometry, and algebra. Hambly and Lyons (Annals of Math, 2010) built upon earlier work of Chen, showing how the signature represents the path uniquely up to generalized …

WebThe main objective of my research is to explore di erent applications of rough path signatures. Developed in the 1990s by Terry Lyons, rough path theory aimed to study di erential equations driven by rough signals. However, over the past decade the use of signatures in various applications such as data science has opened a new line of research. WebOct 23, 2016 · Abstract: In the context of controlled differential equations, the signature is the exponential function on paths. B. Hambly and T. Lyons proved that the signature of a bounded variation path is trivial if and only if the path is tree-like. We extend Hambly–Lyons' result and their notion of tree-like paths to the setting of weakly geometric rough paths in …
