Deep learning for missing value imputation of continuous data and the effect of data discretization

作者:

Highlights:

• Deep learning for imputing missing continuous values of tabular or structured data is studied.

• In particular, multilayer perceptron (MLP) and deep belief networks (DBN) are employed.

• Two different ordered combinations of data discretization and imputation steps are examined.

• MLP and DBN significantly outperform the baseline imputation methods.

• DBN is the better choice for imputation when the discretization of continuous data is required.
