Abstract

fetched live from OpenAlex

In this paper, an analysis of the international financial markets was developed in response to different crisis events. The aim of this work is to evaluate the impact of these events that occurred from the year 2007 to 2022. Through the exploration of different representative stock indices of the international capital markets, it was possible to observe the dynamics in the valuation of the shares, as well as the application of machine learning models and grouping techniques such as hierarchical clustering made it possible to verify that the markets had differentiated responses to these events, which are associated with the geographical location of each market.

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.
