Multivariate time series data in practical applications, such as health care, geoscience, and biology, are characterized by a variety of missing values.
PyPOTS is an open-source Python library dedicated to data mining and analysis on multivariate partially-observed time series, i. e. incomplete time series with missing values, A. K. A.
A user-driven case-based reasoning tool for infilling missing values in daily mean river flow records
In this work, we introduce gapIt, a user-driven case-based reasoning tool for infilling gaps in daily mean river flow records.
Existing methods address this estimation problem by interpolating within data streams or imputing across data streams (both of which ignore important information) or ignoring the temporal aspect of the data and imposing strong assumptions about the nature of the data-generating process and/or the pattern of missing data (both of which are especially problematic for medical data).
