Label Propagation for Learning with Label Proportions
Learning with Label Proportions (LLP) is the problem of recovering the
underlying true labels given a dataset when the data is presented in the form
of bags. This paradigm is particularly suitable in contexts where providing
individual labels is expensive and label aggregates are more easily obtained.
In the healthcare domain, it is a burden for a patient to keep a detailed diary
of their daily routines, but often they will be amenable to provide higher
level summaries of daily behavior. We present a novel and efficient graph-based
algorithm that encourages local smoothness and exploits the global structure of
the data, while preserving the `mass' of each bag.Comment: Accepted to MLSP 201
