Embedding 0.6.0

Store a vector and (optionally) the algorithm or embedding model which generated it. Supports both array (dense) and object (sparse) representations.

This is an older version of embedding.

The latest version is 0.8.0. Releases before 0.7.0 use the $id https://dorsalhub.com/schemas/open/embedding and are served by DorsalHub.

Fields

model string

The model, tool or algorithm used to create this embedding.
- at most 1024 characters
target string

The name of or a reference to the variable, feature, or file being embedded.
- at most 256 characters
vector array of number | object required

The embedding vector data.
Exactly one of these forms:
1. Array Representation array of number
  
  A flat list of numbers (typically used for dense vectors).
  - 1 to 16384 items
2. Object Representation object
  
  A coordinate list of indices and values (typically used for sparse vectors). 'indices' and 'values' must be the same length, and every index must be less than 'dimensions'.
  - dimensions integer required
    
    The total size of the vector space (e.g. the vocabulary size).
    - ≥ 1
  - indices array of integer required
    
    The positions of the non-zero elements.
    - 1 to 100000 items
    - items must be unique
    - each ≥ 0
  - values array of number required
    
    The values corresponding to the indices.
    - 1 to 100000 items
attributes object

Arbitrary metadata relevant to this embedding.
- at most 16 properties
- keys at most 128 characters
- * string | number | boolean | null
  
  Any other key.
  - string: at most 1024 characters
