Orthogonally decomposable tensors

I know nothing about orthogonally decomposable tensors, but they look at a glance to generalise your usual linear algebra in a way useful for the statistical inference of mixture models, while nonetheless being more computationally tractable than your garden variety tensor methods, which would be useful if it is indeed so.
