CLIBD: Bridging Vision and Genomics for Biodiversity Monitoring at Scale
Keywords: Multimodal Learning, Contrastive Learning, DNA Barcodes, Taxonomic Classification, Fine-grained Classification, Biodiversity Monitoring
TL;DR: CLIBD uses a multimodal machine learning approach with images, DNA, and text to enhance insect classification, outperforming traditional methods in identifying known and unknown species without specific fine-tuning.
Abstract: Measuring biodiversity is crucial for understanding ecosystem health. While prior works have developed machine learning models for taxonomic classification of photographic images and DNA separately, in this work, we introduce a multi-modal approach combining both, using CLIP-style contrastive learning to align images, barcode DNA, and text-based representations of taxonomic labels in a unified embedding space. This allows for accurate classification of both known and unknown insect species without task-specific fine-tuning, leveraging contrastive learning for the first time to fuse DNA and image data. Our method surpasses previous single-modality approaches in accuracy by over 8% on zero-shot learning tasks, showcasing its effectiveness in biodiversity studies.
