Structured Problem Solving and Decomposition Questions

Frameworks and practices for framing ambiguous problems, decomposing complexity into tractable components, and designing an investigative plan. Includes problem framing, hypothesis tree and funnel approaches, logical decomposition of metrics and processes, prioritization of diagnostic paths, and communicating a clear problem statement and scope. Emphasis on translating vague business issues into testable questions, mapping metrics to subcomponents, and sequencing investigations based on impact and likelihood.

Sequence investigative steps to diagnose intermittent training instability (loss oscillation) observed during distributed training runs. Consider data shuffling, batch-size vs LR interplay, batch normalization across devices, mixed precision, random seeds, and recent code changes. Which logs and experiments would you run first to reproduce and isolate the issue?

Explain the difference between a well-framed problem statement and a vague business request in the context of building an AI system. Provide a concrete example: convert the request "improve personalization" into a concise problem statement that includes objective, primary success metrics (with units), key constraints (latency, privacy, training budget), and stakeholders to involve.

Perform a cost-benefit analysis for running a full model retrain daily versus weekly on a 50M-sample dataset. Include compute cost estimates, expected freshness benefit (reduction in error), human review overhead, risk of overfitting/noisy updates, and operational complexity. State assumptions clearly.

Design an instrumented investigation plan to isolate non-deterministic intermittent failures that affect roughly 0.1% of predictions. Describe reproducible logging, sampling strategies, end-to-end request ids, environment capture (container image, GPU driver), and statistical techniques you'd use to locate root causes.
MediumTechnical

For a multi-stage ML pipeline (data ingestion → feature store → training → serving), map the most valuable instrumentation points and the specific metrics or logs you would collect at each point. Explain how to connect identifiers across stages so you can build a hypothesis tree that traces issues end-to-end.
