Dissect the Data
Study the dataset structure, file layout, columns, and samples, noting key observations that shape a practical baseline.
Inspect the Problem
Read the constraints, scoring, allowed tools, and edge cases, identifying hidden traps that could change the baseline.
Validate the Baseline
Build a simple yet solid baseline, run it end-to-end, and verify each prediction, metric, and submission file.
Enhance the Heuristics
Use error analysis, ablations, and small refinements to boost baseline performance after the first run is trusted.
