When substituting for a data point, it is known as " unit imputation "; when substituting for a component of a data point, it is known as " item imputation ".

Witryna28 lip 2024 · Multivariate imputation by chained equations (MICE) is an imputation method based on Fully Conditional Specification, where different models impute incomplete attributes. Hence, MICE can impute missing values in datasets with continuous, binary, and categorical attributes by using a different model for each … Witrynain time series. It outputs an imputed time series dataset. The discriminator attempts to identify which components are ob-served and which ones are imputed by the generator. We arm the discriminator with a temporal reminder matrix that encodes a proportion of missing information in the original time series data. Using the temporal reminder ...
