DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MPML/90/">Se
 mi-Supervised Learning and the infinite-Laplacian (Lectures 1 & 2)</a>\nby
  José Miguel Urbano (KAUST) as part of Mathematics\, Physics and Machine 
 Learning (IST\, Lisbon)\n\n\nAbstract\nMotivated by a recent application i
 n Semi-Supervised Learning (SSL)\, the minicourse is a brief introduction 
 to the analysis of infinity-harmonic functions. We will discuss the Lipsch
 itz extension problem\, its solution via MacShane-Whitney extensions and i
 ts several drawbacks\, leading to the notion of AMLE (Absolutely Minimisin
 g Lipschitz Extension). We then explore the equivalence between being abso
 lutely minimising Lipschitz\, enjoying comparison with cones and solving t
 he infinity-Laplace equation in the viscosity sense.\n
