For example, the identity matrix (all zeroes except for ones on the diagonal) is given by the ith element of the jth row is the Kronecker delta of i and j.

Simple things like '0', the identity matrix, 'i', 'e', 'pi', can have profound implications but by themselves seem anywhere from trivial to self-evident. Rather than pontificate (bombasticate, wax reflectively) on my own experiences/random-thoughts/free-associations, I'd be interested in what others here might know of where the Kronecker Delta would be likely applicable to the types of things many of us (might?) assume Tom is interested in (application to big data, natural language processing, etc. in the context of Journalism?)
Kronecker delta Is trivial. It has two arguments. If they're equal the result is 1. If not the result is 0.
