WebbIn practice, using SimpleImputer might often be enough, at least as a first try. But there are several more advanced methods that might also be relevant. One of the most classical ones is based on nearest neighbors and implemented in the KNNImputer. The KNNImputer imputes each missing value using a combination of it’s k nearest neighbors.
