In probability theory, Talagrand's concentration inequality is an isoperimetric-type inequality for product probability spaces. It was first proved by the French mathematician Michel Talagrand. The inequality is one of the manifestations of the concentration of measure phenomenon.〔 ==Statement== The inequality states that if is a product space endowed with a product probability measure and is a subset in this space, then for any : where is the complement of ''At'' where this is defined by : and where is Talagrand's convex distance defined as : where , are -dimensional vectors with entries respectively and is the -norm.
