MaMI dataset
Bibliographic record
Abstract
The mammalian MRI (MaMI) data set is a comprehensive database that encompasses high-resolution <em>ex vivo</em> diffusion and structural (T1- and T2-weighted) MRI scans of 124 mammalian species, and a total of 225 scans including replicas. This data set was originally used by Yaniv Assaf (Assaf, Y. et al., 2020, Nat. Neurosci.; doi: https://doi.org/10.1038/s41593-020-0641-7). The version of the data set included in this repository only includes the network matrices obtained from the MRI scans. Details on the preprocessing of the data and the reconstruction of the matrices can be found in Suarez, LE. et al., 2022, bioRxiv; doi: https://doi.org/10.1101/2022.03.11.483995.
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.
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; both teacher heads agree on what is shown here.
