Expand description
How a vector is compared, as the byte the image stores.
The same four values yo_shape::Metric has, written down here because this
crate is the format and it does not depend on the shape crate. A collection
built for cosine and searched as L2 answers wrongly and quietly, so the
metric travels with the image rather than being taken on trust from whatever
opened it.
Constants§
- COSINE
- Cosine similarity, stored as unit vectors.
- HAMMING
- Hamming distance.
- IP
- Inner product.
- L2
- Euclidean distance.
Functions§
- is_
known - Whether
bis a metric this version has a name for.
