JSON schemas for models

JSON schemas for models

  • model-schema.json A generic ML model, containing fields shared by most models despite of their concrete type. It uses:
    • sample-schema.json The schema for dataset sampling specifications
    • field-collection-schema.json Auxiliary schema describing a collection of field (or "properties") descriptors
    • generic-field-schema.json Properties shared by all fields, regardless of their type.
    • field-schema.json The union schema of all field descriptor types, with their specific properties.
  • tree-model-schema.json A specialization of the model schema to decision tree models. It uses:
  • node-schema The schema for the nodes in a decision tree
