Brasileira de Geofísica Este texto foi preparado para a apresentação no VIII Simpósio Brasileiro de Geofísica, Salinópolis, 18 a 20 de setembro de 2018.Seu conteúdo foi revisado pelo Comitê Técnico do VIII SimBGf, mas não necessariamente representa a opinião da SBGf ou de seus associados.É proibida a reprodução total ou parcial deste material para propósitos comerciais sem prévia autorização da SBGf.____________________________________________________________________ Resumo Desenvolvemos um método de interpretação automática para o mapeamento geológico utilizando a Relação de Poisson entre os campos gravimétricos e magnetométricos.Presumimos que diferentes unidades geológicas apresentam diferentes propriedades físicas, e que a estimação destas propriedades, bem como a da Razão de Poisson, permite mapeá-las.Para mapearmos a Razão de Poisson realizamos a filtragem transformando os campos e a inversão estimando as prioridades físicas sempre no domínio do espaço.Nas inversões, utilizamos os funcionais regularizadores: Suavidade Global e Variação Total.Aplicamos estes procedimentos a um conjunto de dados sintéticos e a metodologia mostrou-se efetiva para o mapeamento de unidades geológicas.

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.
