Abstract

fetched live from OpenAlex

This study presents an innovative federated learning framework that addresses the challenge of identifying the breeds of Iranian sheep using an SNP-based genotype dataset which contains the SNP values of four breeds of Iranian sheep. In the first phase of the research, an SNP selection phase is performed using the Particle Swarm Optimization algorithm to find the best subset of SNPs which will result in the best possible classification accuracy. In this phase, PSO detected 5565 SNPs among 46000 which has resulted in 98% classification accuracy. The second phase then uses a federated learning framework with the aggregation algorithm kfedAvg to train different local learning models with different private local datasets. The result achieved from this phase indicates, on average, the accuracy of 85% by the clients on the local test data.

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.

Full frame distilled prediction

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.
