Perceptron to MLP: Inputs & Outputs

Inputs & Outputs for Perceptron to MLP.

Inputs and outputs contract

Inputs & Outputs for Perceptron to MLP focuses on model capacity vs error trend, parameter count, and inference latency estimate. The goal is to connect model behavior to hardware-aware decisions and operational risk.

Use this as a signed interface contract. Missing assumptions here create expensive rework loops between ML, EDA, and silicon teams.

INPUTS
  - dataset scope + split policy + revision tags
  - model architecture + training/inference config
  - runtime / compiler / hardware target assumptions
  - acceptance criteria tied to VLSI workflow outcome

OUTPUTS
  - quality metrics with calibration and confidence bands
  - runtime profile (latency / bandwidth / utilization)
  - signoff-correlation report for workflow impact
  - release or rollback decision memo

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.
