G032 HIGH RESOLUTION IMAGING M.D. SACCHI 1 J. WANG 1 and H. KUEHL 2 1 University of Alberta Department of Physics Institute for Geophysical Research Edmonton AB Canada T6G 1W2 2 Shell Canada Calgary Summary ¢¡¤£¥£ ¦¨§�©���£¥£¥� Linearized inversion of seismic data entails minimizing a cost function � ¦ of the § form where denotes the forward modeling operator that maps an angle dependent reflection strength to � a measurable seismic wavefield . Minimizing the cost function in the least squares sense leads to the so-called leastsquares migration methods. Migration algorithms on the other hand are capable of estimating

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.
