AUC comparison of SCALP for varying λ in Equation 5.
| λ | 0.99 | 0.90 | 0.85 | 0.80 | 0.75 | 0.70 |
|---|---|---|---|---|---|---|
| AUC | 0.766 | 0.794 | 0.822 | 0.839 | 0.818 | 0.785 |
A higher value of λ implies lower weight to the contrastive loss. Scalp achieves the best performance when 80% weight is given to classification loss and 20% weight is given to contrastive loss.
