Powell singular function

WebSuch functions, albeit easy to understand, are rare in machine learning. Let us study a function with multiple minima. We have introduced Himmelblau's function in the module on Calculus. $$ f(x,y) = (x^2 + y - 11)^2 + (x + y^2 - 7)^2 $$ Himmelblau's function is nonconvex with 4 minima (marked in green) and 1 local maximum (marked in blue). WebFrom the production gate, the function may consider (where appropriate) operational use-life, recycling, secondary use, and sequestration of carbon in the product or biosphere. Panels: (a) Geologic sequestration of industrially captured CO 2 in either onshore well-regulated or poorly-regulated or offshore well-regulated reservoirs (b) carbon sequestered …

For each interval, you sample the function at a few carefully chosen points to obtain surprisingly high accuracy. There are different methods depending on the number of points in each interval, but the simplest is the 2-point method. WebAdj.
