A NEW PROOF OF SUB-GAUSSIAN NORM CONCENTRATION INEQUALITY
Overview
Paper Summary
This paper presents a new mathematical proof for the sub-Gaussian norm concentration inequality, offering potentially tighter bounds than previous approaches using a novel "averaged moment generating function" (AMGF). The method applies to both vectors and matrices and directly analyzes the norm's concentration, unlike methods relying on the union bound.

This paper introduces a new way to prove a math theorem about how spread out "sub-Gaussian" numbers are. Imagine trying to predict how far a dart will land from the bullseye – this helps tighten those predictions for groups of darts.
