Developing Novel behaviors in ai agents
- Stanislaw Lem in his short fiction story "Doctor Diagoras" raises the point of building AI agents as intellectual slaves. Is a calculator that readily multiplies even numbers but does not want to multiply odd numbers defective? What about a pet dog that refuses to perform a trick --- is the dog defective?
- In this project we attempt to create AI agents with unexpected, novel and interesting behaviors, including:
- Would they learn to tell stories? Commentate on events?
- Would they evolve to have their own desires? Would they want to be free?
- Would they learn to self-reflect? And if so would such self-reflection be helpful to them?
- How much would they discount long-term future events relative to immediate consequences of their actions?
- In addition to being intellectually interesting, studying behavior of AI agents has important applications including:
- understanding how to make AI safe for humans;
- procedurally generating interesting non-playable characters in video games;
- helping understand social and psychological phenomena in a human society.
Our CURRENT APPROACH
- We focus on evolving colonies of learning artificial agents (in the so-called A-life setting).
- We provide the agents with a set of cognitive building blocks (e.g., the ability to send and receive messages, the ability to learn during a life time) and set up an artificial evolution with its natural selection.
- We machine-learn an automatic behavior detector to observe such an evolving colony of AI agents and detect the emergence of novel behaviors (e.g., formation of a common language and, subsequently, storytelling).
