Abstract

fetched live from OpenAlex

For the influences of noise,interpolation and image modality,the medical image registration method based on mutual information or normalized mutual information would cause local extrema,small convergence area,and even inaccurate registration.A new generalized Jensen-Schur measure was defined,which used nonlinear increasing of butterworth function to eliminate false extrema.Four new generalized Jensen-Schur measures,mutual information and normalized mutual information were analyzed and compared by applying them to rigid registration.The results of tests show that the new constructed JS22 and JS23 measures outperform other measures in noise immunity and convergence,and eliminating false extrema caused by PV interpolation.

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.
