Coarse Coding Overlap Count

Problem

Compute the fraction of coarse-coding receptive fields that are strictly positive in a feature vector. An empty vector returns 0.0.

Hint

Overlapping receptive fields give generalization between nearby states.

case 1

in: [[1,0,1,1]]

expected: 0.75

case 2

in: [[0,0]]

expected: 0

case 3

in: [[0.5]]

expected: 1

case 4

in: [[]]

expected: 0
