Running average of a convex function
Did you know?
WebbAcross all participants, we observed a relationship between an individual’s typical level of binocular visual function and the degree to which gaze is shifted toward the body. Thus the gaze–gait relationship is sensitive to the level of sensory uncertainty, and deficits in binocular visual function (whether transient or long-standing) have systematic effects on … WebbExamples of convex functions: ax+ bfor any a;b2<; exp(ax) for any a2<; x for x 0, 1 or 0. Another interesting example is the negative entropy: xlogxfor x 0. Examples of concave functions: ax+bfor any a;b2<; x for 2[0;1] and x 0; logx for x 0.

In this post we describe the high-level idea behind gradient descent for convex optimization. Much of the intuition comes from Nisheeth Vishnoi’s short course, but he provides a more theoretical treatment, while we aim to focus more on the intuition. We first describe why to use gradient descent. case nanuk
