Optimistic knowledge gradient

In statistics The optimistic knowledge gradient is a approximation policy proposed by Xi Chen, Qihang Lin and Dengyong Zhou in 2013. This policy is created to solve the challenge of computationally intractable of large size of optimal computing budget allocation problem in binary/multi-class crowd labeling where each label from the crowd has a certain cost.

Finding The Gradient Of A Straight Line | Graphs | Maths | FuseSchool

The gradient of a line tells us how steep the line is. Lines going in this / direction have positive gradients, and lines going in this \ direction have negative gradients. The gradient can be found by finding how much the line goes up - the rise, and dividing it by how much the line goe
