fMRI and DOI Non-Rigid Registration with Discrete Curvature Flows and Mutual Information
Bibliographic record
Abstract
Combined fMRI and optical imaging of intrinsic (hemodynamic) signals has been performed in earlier studied simultaneously. Simultaneous measurements showed a general spatial overlap, low TR (2 sec) and a poor spatial resolution (0.5x1 mm in=plane, slice thickness=2mm) from. Good correspondence between BOLD signal and optically measured Hb was also shown in simultaneous fMRI/DOI human studies, albeit on a low-resolution spatial scale inherent to diffuse optical methods. Multiple-wavelength (spectroscopic) optical imaging of the intrinsic signals enable simultaneous measurements of oxyhemoglobin (HbO), deoxyhemoglobin (Hb) and total hemoglobin (HbT). Quantitative estimates of the concentrations of Hb, HbO, and HbT are obtained by fitting the observed signal changes at all wavelengths to a model, taking into account the respective absorption spectra of HbO and Hb.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
