Numerical vector

Numerical data

Numerical data is the atomic element which compose numerical vector.

Representation

Keys _id, name, stepId, domainInformation, dataset, project, processingInfo, creationTS , latestUpdateTS are unchanged and follow the classic of representation only dataSpecification keys are changed and are described as above :

• dataSpecification :

  • keyword: Its value is “numericalVector” . Cf to mandatory keys.

  • valueType: Cf to mandatory keys.

    • dataType: Its value is “numerical” . Cf to mandatory keys
    • structureType: Its value is “vector” . Cf to mandatory keys

  • meaning: Its value is “Vector of numerical features” . Cf to mandatory keys.

  • view: Cf to mandatory keys.

  • dataLocationId: Cf to mandatory keys.
