    • Priority: Critical
    • Resolution: Fixed

      Description

      Summary: Create a class hierarchy for learning algorithms and the models those algorithms produce.

      This is a super-task of several sub-tasks (but JIRA does not allow subtasks of subtasks). See the "requires" links below for subtasks.

      Goals:

      • give intuitive structure to API, both for developers and for generated documentation
      • support meta-algorithms (e.g., boosting)
      • support generic functionality (e.g., evaluation)
      • reduce code duplication across classes
