Abstract

fetched live from OpenAlex

Abstract BLAST (Basic Local Alignment Search Theorem) is one of the most elegant, and widely used bioinformatics analysis developed to date. Like many bioinformatic analyses, BLAST uses evolutionary theory as the basis for its assumptions. Therefore, an understanding of evolutionary theory is critical to the appropriate interpretation, and further analysis, of BLAST results. Viewing essentially one‐dimensional BLAST analysis from the perspective of a two‐dimensional phylogenetic analysis has a number of benefits including more accurate identification of the true “top hit”, delineation of gene families, identification of true homologs, and improved functional assignment of orthologs and paralogs. Performing such phylogenetic analyses has become easier, now that semiautomated methods have been developed that permit rough phylogenetic overviews of the data. However, it should be emphasized that phylogenetic analysis must often be customized for a given experiment or research question. Such issues are relevant not only to the further analysis of a BLAST output, but also to similar analyses of outputs from other widely used algorithms for rapid database search. Critical analysis of results is becoming increasingly important as sequence databases increase in both size and complexity – and as we begin to understand that even these large sequence databases are only scratching the surface of the true complexity and variety of sequences that exist in nature.

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.
