Abstract

fetched live from OpenAlex

Les reseaux de capteurs lies a des bases de donnees sont de plus en plus frequemment utilises pour la surveillance de milieux a risques. Ces systemes sont usuellement composes d'un ensemble de capteurs envoyant les mesures effectuees vers une base de donnees centralisee. La frequence des mesures aussi bien que les besoins des utilisateurs imposent a la base des contraintes temps-reel douces, tout en valorisant les donnees les plus recentes. Quant au besoin semi-generalise d'acceder aux donnees en fonction de criteres spatiaux, il impose a son tour des caracteristiques spatiotemporelles. Afin de repondre aux specificites de ces systemes, cet article propose deux methodes d’indexation de donnees. La premiere, dediee a l'indexation d'un grand nombre de donnees issues de capteurs fixes se nomme le PoTree. Son evolution, le PasTree, privilegie la gestion de l'agilite des capteurs et la diversification des methodes d’interrogation

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.
