Geological data handling using Oracle 3D : a study on data services and management
Bibliographic record
Abstract
Efficient management of 3D geological and subsurface models require a robust 3D data modeling environment which can provide the necessary functions and flexibility to enable accessing 3D models in a collaborative work environment through the Internet. This allows geoscientists and geo-engineers to work collaboratively for better, informed decisions. Today, there is no data standard that satisfies the entire 3D geological modelling requirement in a collaborative work environment. This thesis presents the result of a research project that focuses on identifying modelling and analytical requirements of geological models and the usability of existing technologies for both database management and applications that allow sharing 3D models in a collaborative modeling environment. Specifically, it examines current 3D data models and how they can fit into the requirements of the 3D geological modeling. Based on identified system requirements, an integrated solution prototype has been implemented that allows large-scale 3D data management and provides real-time Internet access to the underlying 3D models.

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.
