Optimal Recovery of Missing Values for Non-Negative Matrix Factorization

open access: yesIEEE Open Journal of Signal Processing, 2021
Missing values imputation is often evaluated on some similarity measure between actual and imputed data. However, it may be more meaningful to evaluate downstream algorithm performance after imputation than the imputation itself.
