Agent software comprehension : explaining agent behavior

Lâm, Dũng Ngọc, 1977- 28 August 2008 (has links)
It is important for designers, developers, and end-users to comprehend (or explain) why a software agent acts in a particular way when situated in its operating environment. Comprehending agent behaviors in an agent-based system is a challenging task due to environmental uncertainty and the dynamics and multitude of agent interactions, which must be captured, processed, and analyzed by the human user. While traditional software comprehension answers "what is happening in the implementation?", this research takes a step further to facilitate comprehension by answering "why is the behavior happening in the implementation?". To explain agent behaviors in the implemented system, this research takes the model-checking approach for representing abstracted software behavior and the reverse engineering approach for verifying the expected behavior model against the implementation's actual behavior, while assimilating the terminology and framework from abductive reasoning. This research empirically shows that maintaining accurate background knowledge of how the implementation is expected to behave is crucial in generating accurate explanations of agent behavior. The resulting Tracing Method and accompanying Tracer Tool build on ideas from existing approaches and extend the state-of-the-art to better assist human users (of various skill levels) in comprehending agent-based software by automating many reasoning tasks. The Tracing Method is applied to two domains to demonstrate the capabilities of the Tracer Tool in (1) suggesting background knowledge updates, (2) interpreting actual behaviors from implementation executions, and (3) explaining observed agent behaviors. This research aims to help designers who want to improve agent behavior; developers who need to debug and verify agent behavior; and end-users who want to comprehend agent behaviors. / text

Teaming human-agent in intelligent environment /

Ichalkaranje, Nikhil, Unknown Date (has links)
This thesis presents the innovative design of intelligent agent architectures specifically focusing on their human-agent teaming ability for use in a simulation environment. Agent teaming has gained popularity in recent years. It is believed that three important aspects, communication, co-ordination and co-operation play important roles in agent teaming. Multi agent teaming takes inspiration from human organisational models of team operation, where role playing such as leadership and communicative, co-operative and collaborative skills empower the success of the team. Additionally, the second major step in agent teaming is the “human-centric” nature of the agent. The current trend of agent development is very much concentrated on its agent only interaction within teams. This thesis contributes to the understanding of human-agent teaming within current agent architectures such as Belief Desire Intention (BDI) architectures. / Thesis (PhDComputerSystemsEng)--University of South Australia, 2006.

Adaptive trust modeling in multi-agent systems: utilizing experience and reputation

Fullam, Karen Katherine, 1977- 28 August 2008 (has links)
Trust among individuals is essential for transactions. A human or software agent in need of resources may reduce transaction risk by modeling the trustworthiness of potential partners. Experience- and reputation-based trust models have unique advantages and disadvantages depending on environment factors, including availability of experience opportunities, trustee trustworthiness dynamics, reputation accuracy, and reputation cost. This research identifies how trusters may utilize both experience- and reputation-based trust modeling to achieve more accurate decision-making tools than using either modeling technique alone. The research produces: 1) the Adaptive Trust Modeling technique for combining experience- vs. reputation-based models to produce the most accurate aggregated model possible, 2) a quantitative analysis of the tradeoffs between experience- and reputation-based models to determine conditions under which each type of model is favorable, and 3) an Adaptive Cost Selection algorithm for assessing the value of trust information given acquisition costs. Experiments show that Adaptive Trust Modeling yields an aggregate trust model more accurate than either experience- or reputation-based modeling alone, and Adaptive Cost Selection acquires the optimal combination of trust information, maximizing a truster's transaction payoff while minimizing trust information costs. These tools enable humans and software agents to make effective trust-based decisions given dynamic system conditions.
