Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness

Phys · · 716 words · By Krystal Kasal

Three mathematicians from Caltech and Princeton have proven Talagrand's convexity conjecture, a long-standing problem involving high-dimensional random structures. The proof was achieved by reformulating the geometric problem into probability theory and may have future applications in data science and machine learning.

“In 1995, Michel Talagrand came up with his famous mathematical problem, which asks whether convexity can be "created" in a fixed, uniform number of steps (using operations called Minkowski sums) in any number of dimensions.”
CORROBORATED
Multiple independent web sources (Scientific American and another specialized source) confirm that Michel Talagrand posed the 'convexity conjecture' in 1995 regarding creating convexity in constant steps regardless of dimension.
