SMOTE Interpolation

Problem

Generate a synthetic SMOTE point by interpolating between two minority samples: a[i] + lam * (b[i] - a[i]) for every coordinate. Return the new vector; empty input returns [].

Hint

SMOTE places new minority points on the segment between a seed and one of its neighbors.

Test cases

case 1

in: [[0,0],[2,4],0.5]

expected: [1,2]

case 2

in: [[1,1,1],[3,5,7],0.25]

expected: [1.5,2,2.5]

case 3

in: [[],[],0.5]

expected: []

case 4

in: [[5,5],[5,5],0.9]

expected: [5,5]
