Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Keep the pyramidal-pyramidal weights between the two hidden layers fixed (ablation) | Dendritic error network · MNIST test | test error: 1.96% -> 2.11% | Hurt |
| Learn top-down weights on a slow time-scale while keeping all weights plastic (ablation) | One-hidden-layer dendritic error network · MNIST test | test error: 2.48% | No clear effect |
