Talk:Multilinear subspace learning

Are the arrays here really tensors?
Over at Talk:Tensor is a discussion about whether this MSL stuff is really tensorial. That is, do the multidimensional arrays of numbers used in MSL really represent linear mappings of tensor products of vector spaces, or are they just numbers arranged in a grid? The intro to this article suggests the latter. On the other hand, some of the references do use some tensorial operations such as tensor products and contractions. This leads me to wonder whether there really are tensorial things happening, in a hidden way. Mgnbar (talk) 16:55, 4 March 2011 (UTC)

Multilinear subspace learning#Algorithms; typo?
Is there a typo in that string? "Multilinear subspace learning#Algorithms are higher-order generalizations . . . ." (PeacePeace (talk) 23:47, 20 June 2016 (UTC))
