    <div class="sphx-glr-thumbcontainer" tooltip="NanLVQ `[1]`_ refers to a extension that can be implemented for various distance functions. It uses the partial distance strategy to ignore any NaN values in the data. Another interpretation would be that it imputes the missing values with those of the prototypes. Hence, the distance will be zero, which results in a zero update for the feature containing the NaN value.">
