Biodiversity is crucial for ecosystem stability and resilience, acting as a natural defense against disturbances like climate change and invasive species. It also supports the economy by providing essential resources such as food, medicine, and genetic material. Understanding biodiversity is key for sustainable resource management, ensuring these resources remain available for future generations. BIOSCAN’s global biodiversity assessment aims to comprehensively catalog living organisms worldwide, encompassing the intricate tapestry of insect biodiversity. As a fundamental component of global ecosystems, insects contribute significantly to pollination, nutrient cycling, and overall ecosystem stability, embodying a remarkable diversity of species.

BIOSCAN-5M

A comprehensive dataset containing multi-modal information for over 5 million insect specimens, and it significantly expands existing image-based biological datasets by including taxonomic labels, raw nucleotide barcode sequences, assigned barcode index numbers, and geographical information. Every record has both image and DNA data. 

Attributes

Each record of the BIOSCAN-5M dataset contains six primary attributes:

• RGB image
• DNA nucleotide barcode sequence
• Barcode Index Number (BIN)
• Biological taxonomic classification
• Geographical information
• Specimen size

Benchmark Experiments

BIOSCAN-5M paper proposes three benchmark experiments to demonstrate the impact of the multi-modal data types on the classification and clustering accuracy:

• We pretrain a masked language model on the DNA barcode sequences of the BIOSCAN-5M dataset and demonstrate the impact of using this large reference library on species- and genus-level classification performance.
• We propose a zero-shot transfer learning task applied to images and DNA barcodes to cluster feature embeddings obtained from self-supervised learning, to investigate whether meaningful clusters can be derived from these representation embeddings.
• We benchmark multi-modality by performing contrastive learning on DNA barcodes, image data, and taxonomic information. This yields a general shared embedding space enabling taxonomic classification using multiple types of information and modalities.

BIOSCAN-1M 

In 2023, we proposed a rich repository featuring one million intricately labeled insect images. Each entry underwent expert taxonomic classification and was enriched with genetic data, including raw nucleotide barcode sequences and barcode index numbers—a genetic-based proxy for species classification. The BIOSCAN-1M Insect Dataset is designed primarily to support the training of advanced computer-vision models for image-based taxonomic assessments. Apart from its application in machine learning, it distinguishes itself with unique attributes including distinctive long-tailed class-imbalance distribution commonly observed in biological datasets. The taxonomic labeling adopts a hierarchical classification scheme, presenting a nuanced and fine-grained challenge, particularly at finer-grained taxonomic levels. This distinctive feature not only advances machine learning but also extends its relevance to the broader machine learning community. The initial phase of the project has been successfully completed with the release of the BIOSCAN-1M Insect Dataset, featured in the Advances in Neural Information Processing Systems (NeurIPS 2023) Datasets & Benchmarks Track. 

Attributes

Each record of the BIOSCAN-1M Insect dataset contains 4 primary attributes:

• RGB Image
• DNA nucleotide barcode sequence
• Barcode Index Number (BIN)
• Biological taxonomic classification

Benchmark Experiments

BIOSCAN-1M Insect paper proposes two benchmark experiments on three subsets of the dataset:

• Image-based taxonomic classification on 16 distinct taxonomic orders within the insect community.
• Image-based taxonomic classification on 40 distinct taxonomic families within the insect community.
