Abstract
The Bank of Canada uses core CPI inflation, the year-over-year rate of change of the consumer price index excluding food, energy, and the effects of changes in indirect taxes, as the operational guide for monetary policy. In this report we study the concept and measurement of core or underlying inflation more generally by examining several alternative measures of core inflation, from the viewpoint that core inflation is a tool for policy purposes, either as an indicator of current and future trends in inflation, or as a viable target for monetary policy. A simple model of price determination is proposed that defines the core conceptually, and illustrates the process by which aggregate inflation rates may differ from the core. As a measure of inflation for policy purposes, core inflation is useful to the extent that it can be measured accurately. Therefore, following a discussion of conceptual issues, the report's focus narrows and we introduce the various measures of core inflation, concluding with a comparative evaluation of those measures. We find the alternatives quite similar in many respects. However, a closer assessment based on their suitability to various policy purposes suggests that different measures do well along different dimensions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
