Bounding mutual information given bounds on pointwise mutual information Yes, it is certainly true that pmi$(x,y)$ can be equal for all $x$ and $y$, but that does not rule out a tighter bound. For example, it is not hard to prove that $I(X; Y) \leq k(e^k-1)$. This is $\approx k^2$ when $k < 1$, and is a non-trivial strengthening of the bound $k$ when $k < 1$. I am wondering if there are non-trivial bounds that hold more generally. |
