Engineered Agents

Subsumption agents

• Higher layers can override the inputs or outputs of lower layers

• Gat: "By the common metric that speed equals intelligence, Subsumption appeared to be a major breakthrough."

Three Layer Architectures

Cognitive agents

• ACT-R / SOAR

  • ACT-R

BDI Agents

• See Wayne Wobcke's course

AIXI:

• Agent developed by Marcus Hutter at ANU
• Has strong performance guarantees in general environments
• Is provably not computable, and hence is a theoretical, not practical, system
