Abstract

fetched live from OpenAlex

The goal of this thesis is to analyse the Haezendonck-Goovaerts (HG) risk measure and see how it compares to other well known and used risk metrics. In particular a focus on Expected Shortfall is presented as the main source of comparison due to the similarities between the two risk measures. The Young Function associated with the HG risk measure that will be k focused on will be of the form ’(t) = tk. In the case where k = 1, the HG risk measure is equivalent to Expected Shortfall[1], and it is for this reason in this thesis the focus will be on the k = 2 case. An experiment is then run on the risk measures where a model is used on the returns of a portfolio, and see which gives a more conservative result at the same significance level.

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.
