Missing Labels

The challenge in multi-label learning with missing labels is that the training data often has incomplete label information. Collecting labels for multi-label datasets is a manual exercise and dependent on external sources, leading to the collection of only a subset of labels. This assumption of complete label information doesn't hold, especially when the label space is large. Inaccurate label-label and label-feature relationships can be captured, leading to suboptimal solutions in missing label settings.
