Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Add TAIL-τ instance-based staleness-adaptive step size (mean-preserving) | AsyncSGD (ASYNC, HOG, LSH) on LeNet · MNIST, Fashion-MNIST, CIFAR-10 | wall-clock time to convergence speedup: up to 1.92x (5%) and avg 1.29-1.6x across settings | Helped |
| Replace constant step size with commonly used ×τ^-1 staleness dampening (ablation) | AsyncSGD on MNIST (MLP and LeNet) · MNIST | convergence rate | Hurt |
| Replace constant step size with FLeet exponential dampening (ablation) | AsyncSGD on MNIST (MLP and LeNet) · MNIST | convergence rate | Hurt |
| Add TAIL-τ step size to AsyncSGD implementations | AsyncSGD (HOG, LSH, ASYNC) · MNIST and Fashion-MNIST higher-precision convergence | fraction of executions reaching target precision: success ratio 3.53 for MLP MNIST 5%-convergence | Helped |
