Abstract

fetched live from OpenAlex

Since the outbreak of the COVID-19 epidemic, great changes have taken place in the world's economic situation. The interest rate increase by the Federal Reserve has become one of the most influential actions. Researchers have found that the Fed's interest rate hike not only has an impact on the American financial market but also on the world economic situation to a certain extent. Therefore, this paper collects the share price of US dollar and the exchange rate between US dollar and RMB since June, 2021, and uses VAR model and ARMA-GARCH model to model and analyze the data, to examine how the Fed's interest rate hike will affect the dollar's value and Apple's share price, and to predict the future exchange rate and the development trend of Apple's share price in the case of the Fed's interest rate increase, so as to further study the dynamic changes of American technology companies in the uncertain market.

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.
