# Dataset Card for TreeOfLife-10M Vector database
Persistent files for vector Database created with [chromadb](https://docs.trychroma.com/docs/overview/introduction)
containing the embeddings for all images in the [imageomics/TreeOfLife-10M](https://huggingface.co/datasets/imageomics/TreeOfLife-10M) dataset.

This dataset contains the generated vector database built using ChromaDb as the backend vector database solution for the entire TreeOfLife-10M dataset.
The rationale behind creating a vector database was to enable blazingly fast nearest neighbor search.
The vector database is loaded into memory and for a given query embedding in the same dimension as the vectors in the database, we calculate the inner product (ip) to calculate distances.
In this case all vectors are of the same dimension i.e. 512 dims.
The files in this dataset are binaries and cannot be read in raw format. The files in this dataset are intended to be used with chromadb.
Below is an example usage:
```py
import chromadb
client = chromadb.PersistentClient(path=self._collection_dir)
collection = client.get_or_create_collection(
name="imageomics/TreeOfLife-10M",
metadata={"hnsw:space": "ip", "hnsw:search_ef": 10},
)
# returns ID of 10 nearest neighbor. If an exact match exists,
# that will be the first returned result with a distance of 0.
collection.query(query_embeddings=[query_embedding], n_results=10)
```

## Dataset Creation
### Source Data
[imageomics/TreeOfLife-10M](https://huggingface.co/datasets/imageomics/TreeOfLife-10M) dataset was the source for all images in the database.
Along with every image in the database we also store the taxonomic information as additional columns in the vector database:
* kingdom
* phylum
* class
* order
* family
* genus
* species
* common name
The image embedding were generated using the [`TreeOfLifeClassifier`](https://github.com/Imageomics/pybioclip/blob/35ad338bb904d18b295dabf8b23377a343273c06/src/bioclip/predict.py#L429) available in the [pybioclip](https://github.com/Imageomics/pybioclip/tree/main) library.
