The impact of imputation quality on machine learning classifiers for datasets with missing values. [PDF]
Background Classifying samples in incomplete datasets is a common aim for machine learning practitioners, but is non-trivial. Missing data is found in most real-world datasets and these missing values are typically imputed using established methods ...

Benchmarking missing-values approaches for predictive models on health databases. [PDF]
Background As databases grow larger, it becomes harder to fully control their collection, and they frequently come with missing values. These large databases are well suited to train machine learning models, e.g., for forecasting or to extract biomarkers

A note on handling conditional missing values [PDF]
In medical research, some variables are conditionally defined on some levels of another variable, leading to conditional missing data. Imputation of this type of structural missing data is needed given inefficiency of listwise deletion inherent in ...

Capturing Missing Tuples and Missing Values [PDF]
Databases in real life are often neither entirely closed-world nor entirely open-world. Indeed, databases in an enterprise are typically partially closed, in which a part of the data is constrained by master data that contains complete information about the enter prise in certain aspects 121].
