Many of the words used by the machine learning community are gratuitously unrelated to what they mean in other fields. If you hear a ML person use a term and you don't know the ML meaning, you probably need to ask for clarification.
This is true of every field of science and even social science I’ve known. Also the same terms have different meaning in different fields. Also the standard use of a term within a subfield can be different from its usage in another subfield. There are even variations in usage within communities of the same subfield (e.g. inside different ML communities).
