Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

These historical transaction data of financial market are downloaded from the official website of Investing, and which constitute the following stock index dataset, bond index dataset, forex index dataset, and gold index dataset, where the web address is (https://cn.investing.com/). The stock index dataset is mainly composed of 1220 historical opening index values of the four China’s stock indices, which are the Shanghai Securities Composite Index (SSEC), the SZSE Component Index (SZI), the Growth Enterprise Index (CNT), and the SSE SME Composite Index (SZSMEPI). The time period is from January. 1st, 2014 to December. 31th, 2018. The bond index dataset is mainly composed of 1219 historical opening price values of the four China’s bond indices, which are the Shanghai Securities National Bond Index (SSEBI), the Shanghai Securities Company Bond Index (SSECBI), the Shanghai Securities Enterprise Bond Index (SSEEBI), and the Shanghai Securities 5-year Term Credit Bond Inde (SSE5YCB). The time period is from January. 1st, 2015 to December. 31th, 2019. The forex index dataset mainly consists of 1043 historical data of the exchange rate between the four currencies and RMB, which are the United States Dollar to RMB (USD-CNY), the Canadian Dollar to RMB (CAD-CNY), the Euro to RMB (EUR-CNY), and the Swiss Franc to RMB (CHF-CNY). The time period is from January. 1st, 2016 to December. 31th, 2019. The Gold index dataset is mainly composed of 1213 historical opening price values of the four precious metal spots, which are the London gold (XAU), trading-delayed gold (AUTD), London silver (XAG), and trading-delayed silver (AGTD). The time period is from January. 1st, 2015 to December. 31th, 2019. Since the four data sets are all financial time series, they can be used to verify the financial time series model. At the same time, the time series in each data set have a strong correlation, so it can be used to verify the multi-task learning model.

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.

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.
