| Abstract(in English) | A profile in the ARGO ocean observing array can be viewed as a sequence of three-dimensional vectors composed of pressure, salinity, and temperature. Since it appears as a continuous curve in three-dimensional space, the collection of all the iterated integrals, the signature, is able to represent its shape, and the set of signatures fits into an algebraic structure. Moreover, a nonlinear function of the profile shape can be represented by a linear combination of the iterated integrals. Such a mathematical structure allows us to perform machine learning for nonlinear functions with respect to the shape of profiles. This method is applicable to the automatic quality control of the ARGO profile data. |
