Abstract

fetched live from OpenAlex

The fight against parasitic worm infections requires the investigation of a vast array of potential drug candidates. One important tool in this screening is microscopic image classification. These images are acquired from model organisms such as C. elegans exposed to drug candidates. We report a dataset and a novel self-supervised method of clustering and classification to identify natural product extracts that cause Abnormal phenotypes in C. elegans. Our method, Triple Cluster Classification (TriCC), has the ability to identify patterns in C. elegans that accurately map to 27 observed phenotype combinations with a weighted average area under ROC curve of 0.8. In binary classification, to identify drugs with any impact, the area under the ROC curve is 0.89.

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.

Teacher imitation

Not 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.
