| | Bottom Line | It is difficult but possible to integrate predictive learning and behavior control into complex agent architectures using constructionist approaches (hand-coding); better methodologies are needed. | | | Bottom Line | It is difficult but possible to integrate predictive learning and behavior control into complex agent architectures using constructionist approaches (hand-coding); better methodologies are needed. | |

| | Complex | Complexity stems from interaction among parts, many of which are generated by the system at runtime and whose complexity may mirror some parts of the task-environment (if task-environment is complex, and lifetime is long, the resulting control structures are likely to be complex as well). \\ Examples: NARS, AERA. | | | Complex | Complexity stems from interaction among parts, many of which are generated by the system at runtime and whose complexity may mirror some parts of the task-environment (if task-environment is complex, and lifetime is long, the resulting control structures are likely to be complex as well). \\ Examples: NARS, AERA. | |
| | | Transversal Integration | A general-purpose system must tightly and finely coordinate a host of skills, including their acquisition, transitions between skills at runtime, how to combine two or more skills, and transfer of learning between them over time at many levels of temporal and topical detail. | | | | Transversal Integration | A general-purpose system must tightly and finely coordinate a host of skills, including their acquisition, transitions between skills at runtime, how to combine two or more skills, and transfer of learning between them over time at many levels of temporal and topical detail. | |
