 ====== Extreme Multi-Label Classification ======
+Extreme multi-label classification (or extreme multi-label learning, XML) is the task of matching an input with 0 or more labels (the most relevant labels) from an extremely large label set.  The space of outputs is $2^L$, where $L$ is a large set.  This is different from multi-class classification, where each instance has only one associated label.  It has been used for recommendations and product search.  Search and IR can also be formulated as XML.
