About These Notes These are the lectures notes of a graduate course I o ered in the Dept. IFT 6085 - Theoretical principles for deep learning Lecture 2: January 9, 2020 often breaks down without the convexity assumption. A function F: Rd!R is convex if dom(F) ˆRdis convex … A consequence of the de nition is that C is also path-connected, i.e., two By convention: empty set ;is convex. lecture, we shift our focus to the other important player in convex optimization, namely, convex functions. 2 Convex Analysis We’ve been using convexity at various points throughout the course, but here are some de nitions that will be useful especially today. Lecture slides in one file. Lecture notes files. De nition 2 (Convex Function). They cover the basic theory of convex sets and functions, several avors of duality, a variety of optimization algorithms (with a focus on Lecture note 1 Convex optimization 1.3 Convex sets 1.3.1 De nitions De nition 1 A set CˆRnis called convex if for every pair of x;y2C, the entire line segment: [x;y] := fz: z= x+ (1 )y: 0 1gˆC.

Loewen In trust region methods, we minimize a quadratic model function M = M(p) over the set of all p2Rnsatisfying a constraint g(p) def= 1 2 kpk2 − 0: (Here >0 is given.) My goal was to get students acquainted with methods of convex analysis, to make them more comfortable in following arguments that appear in recent Filter design and equalization. of Elec-tronics and Telecommunications Engineering at Istanbul Technical University.
