There are so many flavors of machine learning that we should probably just refer to whole field as XML.
At some point we might need to cross-reference (X-ref) language models. This may involve using a dedicated data interchange format - perhaps an extensible markup language for language model cross-referencing. Or, in short, LMX-XML.
My mind still unabbreviates "ML" into "Machine Language" before anything else, only because it was the first of these three for me.
