Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| lower learning rate from 0.01 to 0.0001 (ablation) | BNN · ImageNet | top-5 accuracy: 43.5 -> 61.3 | Helped |
| PReLU instead of ReLU (absorbing scale factors) (ablation) | BNN · ImageNet | top-5 accuracy: 61.3 -> 65.6 | Helped |
| binarize last layer (no scale layer) (ablation) | BNN · ImageNet | top-5 accuracy: 65.6 -> 61.0 | Hurt |
| add scale layer after binarized last layer (ablation) | BNN · ImageNet | top-5 accuracy: 61.0 -> 64.6 | Helped |
| binarize last layer with scale layer (ablation) | BNN · ImageNet | compression rate: 5.98× -> 27.1× | Helped |
| multiple binarizations of activations (m=2) (ablation) | BNN · ImageNet | top-5 accuracy: 64.6 -> 70.4 | Helped |
| expand lower layers of baseline network (ablation) | BNN 2-bit · ImageNet | top-5 accuracy: 70.4 -> 75.6 | Helped |
| bipolar regularizer instead of L2 (ablation) | BNN · ImageNet | training loss stability | Helped |
| full method vs XNOR-net ResNet-18 | binary networks · ImageNet | top-5 accuracy: 73.2 -> 75.6 | Helped |
