Abstract

fetched live from OpenAlex

Abstract We survey methods for backtesting risk models using theex anterisk measure forecasts from the model and theex postrealized 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 dailyex anterisk model forecast and the dailyex postcorresponding profit and loss. In particular, knowledge about the assumptions behind the risk model and its construction is not required.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
