Introduction to the signature method
Nozomi Sugiura
The sequential data observed in earth science can be regarded as paths in multidimensional space. To read the path effectively, it is useful to convert it into a sequence of number…
Clustering global ocean profiles according to temperature-salinity structure
Nozomi Sugiura
An unsupervised clustering using a Gaussian mixture model is applied to Argo profiles distributed over the entire ocean. We employ as the coordinate components in feature space the…
Estimating the population mean for a vertical profile of energy dissipation rate
Nozomi Sugiura, Shinya Kouketsu, Shuhei Masuda +2
Energy dissipation rates are an important characteristic of turbulence; however, their magnitude in observational profiles can be incorrectly determined owing to their irregular ap…
Machine learning technique using the signature method for automated quality control of the Argo profiles
Nozomi Sugiura, Shigeki Hosoda
A profile from the Argo ocean observation array is a sequence of three-dimensional vectors composed of pressure, salinity, and temperature, appearing as a continuous curve in three…
