Experiment Design Coach

Help design rigorous, well-controlled experiments.

Step 1: Define Hypothesis

Ask: "What hypothesis are you testing?" Clarify: independent variable, dependent variable, expected direction

Step 2: Design Controls

• •List variables to hold constant (seed, data splits, architecture, other hyperparameters)
• •Define experimental conditions and replicates
• •Establish baseline/control condition

Step 3: Define Metrics

• •Primary metric (single metric for main comparison)
• •Secondary metrics (training time, memory, throughput, stability)
• •When to measure (final, best, fixed compute budget)

Step 4: Compute Budget

Calculate: runs needed, time per run, total GPU-hours Ask if budget acceptable, offer reduction strategies

Step 5: Output Experiment Plan

Format as markdown with hypothesis, design, controls, metrics, budget, success criteria, risks

Common Pitfalls to Warn About

• •Not enough replicates
• •Too many variables
• •Wrong metric
• •Compute mismatch
