Abstract

fetched live from OpenAlex

This paper presents and experiments with a new validation dataset using a method that models anoxia in estuaries. The proposed method incorporates nonlinear time series characterization, time delay methods, unsupervised techniques for intrinsic dimensionality estimation, and manifold learning to predict anoxic events. Characterizing dissolved oxygen time series with features derived from nonlinear time series analysis effectively identified families of series exhibiting differences in their dynamics. The built models showed high correlations and relatively low errors, thus validating the approach on these additional data. However, further work is needed to develop more advanced models capable of operating with time-ordered events.

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.
