We outline sampling plans, annotation guidelines, and lightweight audits you can lead to raise signal, reduce bias, and protect privacy without writing scripts.
Cut through jargon with intuitive pictures of classification, regression, embeddings, ranking, and generative models. Compare strengths, failure modes, and data needs. You will speak confidently about baselines, ablations, and overfitting, enabling faster decisions and smarter bets when science partners propose alternatives with different risks and payoffs.
Translate human value into numbers: latency users feel, task completion, containment, false positive cost, fairness, and long‑term retention. Learn to connect offline metrics to business KPIs through phased experiments, guardrail thresholds, and honest dashboards that communicate uncertainty, avoid cherry‑picking, and guide responsible rollouts in complex, evolving environments.
