Retraining Cost-Benefit

Problem

Compute the expected net benefit of retraining: drift_prob * daily_loss * days_saved - retrain_cost.

Hint

Retrain only when expected avoided loss exceeds the retraining cost.

case 1

in: [0.8,100,3,200]

expected: 40

case 2

in: [0.1,100,2,500]

expected: -480

case 3

in: [0,5,1,10]

expected: -10
