What is Field Types in Machine Learning

Each field (feature, prediction value, raw input or actual value) has a field type that must be explicitly defined during model version creation.

The available field types are:

  • numeric
  • boolean
  • categorical – the categories must be numbers
  • string – a categorical field with string values
  • datetime – this can contain either python datetime objects, or an ISO-8601 timestamp string
  • vector – currently not supported in predictions
  • text – not supported in features and predictions
