New Transformer Model Enhances Arthropod Abundance Estimation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed BIOTRAM, a novel neural network designed to improve the accuracy of arthropod abundance estimates derived from metabarcoding. This biochemistry-informed transformer model addresses limitations in traditional methods where DNA read counts do not directly correlate with relative abundance due to varying amplification rates and specimen sizes. BIOTRAM learns a read yield per specimen, significantly reducing the Jensen-Shannon divergence from 0.3586 to 0.1200 compared to raw read proportions. The model also demonstrates superior generalization capabilities, outperforming other deep architectures and baselines on out-of-domain datasets from different regions, collection dates, and laboratories.

    BIOTRAM: Biochemistry-informed Transformer for Relative Abundance via Metabarcoding

    arXiv:2611.05418v1 Announce Type: cross Abstract: Arthropod monitoring at scale begins with metabarcoding of bulk samples: trap collections of hundreds to thousands of specimens processed as one unit, extraction of DNA from the bulked specimens, then sequencing of the DNA from al…
