WebLearn third grade math—fractions, area, arithmetic, and so much more. This course is aligned with Common Core standards. WebGradient descent is an algorithm that numerically estimates where a function outputs its lowest values. That means it finds local minima, but not by setting \nabla f = 0 ∇f = 0 like we've seen before. Instead of finding minima by manipulating symbols, gradient descent approximates the solution with numbers.

Learn how to think about absolute value as distance from zero, and practice finding absolute values. The absolute value of a number is its distance from 0 0. This seems kind of obvious. Of course the distance from 0 0 to 4 4 is \blueD4 4. Where absolute value gets interesting is with negative numbers.
