Reports and metrics

Reports & Metrics for Datasets, Splits & Augmentation focuses on train/val/test leakage score, sample diversity index, and augmentation gain. The goal is to connect model behavior to hardware-aware decisions and operational risk.

Reports must convert train/val/test leakage score, sample diversity index, and augmentation gain into release decisions. Single-number gains are insufficient without workload context, artifact traceability, and owner accountability.

Convergence depends on stable loop timing and signal quality.

• Track train/val/test leakage score, sample diversity index, and augmentation gain across representative workload slices.

• Show quality, latency, and power together for deployment decisions.

• Tag every report with dataset/model/runtime revisions.

• Include confidence and uncertainty, not only point estimates.

Reports and artifacts

• split audit

• augmentation effect report

• hyperparameter tracker

• scaling efficiency chart

Mini case study

A minor split leakage inflated validation gains and delayed a critical workflow decision.

Debug branches

• Rebuild split lineage

• Check seed reproducibility

• Re-run baseline before tuning

Senior review question

Ask: what evidence connects this ML claim to a concrete VLSI workflow decision and owner signoff?

Key takeaways

• Every AI claim should map to a measurable engineering outcome.

• Validate both model quality and hardware/runtime feasibility before adoption.

Common pitfalls

• Optimizing benchmark metrics that do not correlate with signoff goals.

• Ignoring data drift and calibration after deployment.

• Shipping ML workflows without clear rollback ownership.
