The post shares a rare 1956 photo of C. R. Rao with Sir R. A. Fisher and highlights Rao's celebrated 1945 paper.
This foundational work profoundly shaped modern statistics and machine learning, introducing key concepts such as the Cramér-Rao lower bound (setting a theoretical limit on estimator variance), the Blackwell-Rao theorem (a method for improving estimators), and Fisher-Rao geometry.
