Abstract

fetched live from OpenAlex

Abstract We survey methods for backtesting risk models using the ex ante risk measure forecasts from the model and the ex post realized portfolio profit or loss. The risk measure forecast can take the form of a Value at Risk, an expected shortfall, or a distribution forecast. The backtesting can be seen as a final diagnostic check on the aggregate risk model carried out by the risk management team that constructed the risk model or they can be used by external model evaluators such as bank supervisors. The approaches suggested require only information on the daily ex ante risk model forecast and the daily ex post corresponding profit and loss. In particular, knowledge about the assumptions behind the risk model and its construction is not required.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
