Abstract

fetched live from OpenAlex

Processing heterogeneous information is necessary in many domains, but it is specially important in the study of complex systems like geologic phenomena responsible for natural hazards. The developments in sensor, communication and computer technologies allows the monitoring and storage of different geophysical, geochemical and geological variables on a continuous base. In addition, field observation and laboratory analysis incorporate more information, also changing with time. Some of the problems associated with these large masses of information are: (a) the presence of heterogeneous variables (i.e. ratio, interval, nominal, ordinal, and other more complex like images, spectra, etc.), (b) the uncertainty associated with the observed variables in terms of observation or measurement errors, vagueness, subjectivity, etc, and (c) the incompleteness due to monitoring gaps, irregular sampling frequencies and missing data.

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.
