Services and Algorithms

This section describes each of the services compared in the throwdown and the algorithms/models used.

Decision trees.

JSON PML: 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
