| ## Dataset structure |
|
|
| Each dataset is distributed as an HDF5 file. |
|
|
| The HDF5 files contain the following attributes: |
| - dimension: The dimensionality of the data. |
| - distance: The distance metric to use. |
| - point_type: The precision of the vectors, one of "float", "uint8", or "binary". |
| |
| The HDF5 files contain the following HDF5 datasets: |
| - train: numpy array of size (n_corpus, dim) containing the embeddings used to build the vector index |
| - test: numpy array of size (n_test, dim) containing the test query embeddings |
| - neighbors: numpy array of size (n_test, 100) containing the IDs of the true 100 k-nn of each test query |
| - distances: numpy array of size (n_test, 100) containing the distances of the true 100 k-nn of each test query |
| - avg_distances: numpy array of size n_test containing the average distance from each test query to the corpus points |
| |
| Additionally, the HDF5 files of OOD datasets contain the following HDF5 datasets: |
| - learn: numpy array of size (n_learn, dim) containing a larger sample from the query distribution |
| - learn_neighbors: numpy array of size (n_learn, 100) containing the true 100 k-nn (from the corpus) for each point in learn |
