Abstract

fetched live from OpenAlex

We propose a nonrigid registration approach for diffusion tensor images using\na multicomponent information-theoretic measure. Explicit orientation\noptimization is enabled by incorporating tensor reorientation, which is\nnecessary for wrapping diffusion tensor images. Experimental results on\ndiffusion tensor images indicate the feasibility of the proposed approach and a\nmuch better performance compared to the affine registration method based on\nmutual information in terms of registration accuracy in the presence of\ngeometric distortion.\n

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.
