La ocupación paleolítica del Alentejo meridional: investigación en la cuenca del río Sado
Bibliographic record
Abstract
El proyecto de prospección de la cuenca del río Sado (SRDS), llevado a cabo entre el 2004 y el 2008, se diseñó para suplir la carencia de información concerniente al conocimiento actual de la Prehistoria de Portugal. Aunque la cuenca del río Sado conforma casi un tercio de la superficie continental de Portugal, aún no había recibido la debida atención para el Paleolítico. Antes de este proyecto, prácticamente nada se conocía acerca de la Prehistoria de dicha cuenca, incluyendo la llanura de Alentejo. Nuestros resultados indican una baja densidad de población durante el Paleolítico Medio, rastro de ocupaciones del Paleolítico Inferior y casi ninguna evidencia de ocupaciones asociadas al Paleolítico Reciente. A partir de los datos obtenidos, se desprende un modelo en el que se evidencia que, hacia finales del Paleolítico Medio, hubo una discontinuidad en la ocupación, probablemente asociada a cambios climáticos o del uso del territorio.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
