Abstract

fetched live from OpenAlex

植物花粉资料用来恢复千年-万年尺度的气候变化是一种比较成熟的方法, 并取得了大量的成果, 但应用于十年至百年尺度的气候序列重建仍属探讨性研究. 本文采用花粉资料, 以50 a为时间尺度单元, 对加拿大过去1 ka的温度进行了历史重建. 近千年来北美地区气候环境受人为干扰甚少, 1~ 0.1 ka尺度的气候变化主要受自然因子控制, 因此可为认识和鉴定中国千年来气候变化序列中人为影响程度提供有价值的参照系. 此外, 本文所采用的花粉-气候转换法可以为中国的千年尺度的气候重建提供实用技术.

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.
