My first thought was that this was related to multilinear algebra (algebra of tensors and higher-order vector spaces) which has lead to many interesting and suggestive advances in machine learning, but apparently it's not. What a truly opaque collection of nomenclature they've chosen...

After glancing through a couple papers I can't entirely shake the feeling that the entire thing might be a social experiment to see how much jargon and fantastical sound words can be mashed together before people notice it's nonsense (even though I realise it's not).
