Goal-Driven Autonomy (GDA)

Goal Driven Autonomy (GDA) is a new goal reasoning method for problem solving in which autonomous agents dynamically identify and self-select their goals throughout execution. The objective of goal-driven autonomy (GDA) is to enable autonomous agents to direct the focus of their activities, and thus become more self-sufficient.

This project aims to study of Goal-driven autonomy (GDA) agents that are capable of learning expectations, explanations, and goals in such a way that they can (1) identify situations where discrepancies take place between what they expect and what actually happens, (2) explain the discrepancy, (3) decide which goals to achieve as a result of these explanations, and (4) act to accomplish these goals. These agents will be able to act in complex environments, which exhibit nondeterministic action outcomes and are dynamic with changes occurring independently of the agent’s own actions.
