Considering User Preferences In Autonomous Agent Tasks
Autonomous agents working in an environment shared with humans must respond to a variety of changes. Human users have a variety of needs and preferences, and agents should be able to follow those preferences across a wide range of users. This thesis advances human-robot interaction by adapting …

Using Heading to Improve Autonomous Agent Movement on Networks
… diagnosing threats is needed. A mobile software agent system modeled on ants provides one possible solution to this problem. Using this approach, software agents visit nodes (computing devices) in the network and look for evidence of a security threat. Agents operate autonomously, determining the …

A Dynamic Workflow Framework for Mass Customization Using Web Service and Autonomous Agent Technologies
… workflow paths. Strategies for developing an autonomous agent-based framework and for identifying and creating web services for specific process tasks are presented. The proposed methods are outlined in two different case studies to illustrate the approach for both a generic process with …

Robust object exploration and detection
… we explore models and algorithms used by an autonomous agent to find objects in the real world. We begin by tackling the problem of determining the existence and location of an object robustly given the sensors employed on an agent. Our major contribution lies in modeling the spatial …

Explorations into the behaviour-oriented nature of intelligence : Fuzzy behavioural maps.
… development framework for providing complex autonomous agent behaviour. This thesis provides a proof-of-concept for simple FBMs, including some experimental results in Mobile Robotics and Fuzzy Logic Control. This practical work shows the design of a collision avoidance behaviour (of a mobile …

Depression, Volition, and Death: The Effect of Depressive Disorders on the Autonomous Choice to Forgo Medical Treatment
… processes. These models tend to suggest an autonomous agent free from cognitive bias and systematic distortion (e.g., Kantian or Cartesian rational agents). Evidence is emerging from the fields of cognitive psychology, cognitive science, and neuroscience that fundamentally challenge this …

Using Negative Information in simultaneous localization and mapping
The problem of autonomous navigation is one of efficiently utilizing available information from sensors and intelligently processing that information to determine the state of the robot and its environment. This thesis explores a topic often ignored in the Simultaneous Localization And Mapping …

Anticipatory communication strategies for human robot team coordination
Increasing prevalence of autonomous systems has generated interest in effective inclusion of robots as team members in many domains, especially where complex and safety-critical tasks must be performed. We envision a world where autonomous systems can be seamlessly integrated into high performing …

Flexible execution of plans with choice and uncertainty
Dynamic plan execution strategies allow an autonomous agent to respond to uncertainties, while improving robustness and reducing the need for an overly conservative plan. Executives have improved robustness by expanding the types of choices made dynamically, such as selecting alternate methods. …

State discovery for autonomous learning
… algorithms for early perceptual learning for an autonomous agent in the presence of feedback. In the framework of associative perceptual learning with indirect supervision, three learning techniques are examined in detail: * short-term on-line memory-based model learning; * long-term on-line …

Learning State and Action Abstractions for Effective and Efficient Planning
An autonomous agent should make good decisions quickly. These two considerations --- effectiveness and efficiency --- are especially important, and often competing, when an agent plans to make decisions sequentially in long-horizon tasks. Unfortunately, planning directly in the state and action …

Impact of carbon emission regulatory policies on the electricity market : a simulation study
… stakeholders of the electricity market. An agent based simulation approach was used to model the market where each market stakeholder was represented as an autonomous agent. We use the simulation model to compare the effectiveness of cap-and-trade policy and taxation policy in achieving …

Grounding natural language with autonomous interaction
… resource scenarios. In particular, I describe an autonomous agent that can learn to acquire and integrate external information to enhance information extraction. Our experiments on two databases - shooting incidents and food adulteration cases - demonstrate that our system significantly improves …

Learning 3D Robotics Perception using Inductive Priors
… as assumptions of how the world works, helps the autonomous agent generalize better and adapt their behavior based on past experience. In this thesis, I demonstrate the use of prior knowledge in three different robotics perception problems. 1. object-centric 3D reconstruction, 2. vision and …

Blame Ascriptions Toward Autonomous Agents
As autonomous agents become embedded in organizational and everyday contexts, humans are increasingly delegating tasks to them. Yet when undesirable outcomes occur, people may blame the autonomous agent. This thesis investigates how blame is socially expressed, referred to as blame ascriptions, …

‘Talent’ Mentalities: Young People’s Experience of Being in a Sports Talent Development Programme
… the young person or regard the participant as an autonomous agent. This study employed phenomenological enquiry to focus on the conditions of lived reality to afford the young person the opportunity to convey their unique experience. The aim of the research was to employ a participatory approach …

Developing and Coordinating Autonomous Agents for Efficient Electricity Markets
… of data. The methods of game theory and multi-agent systems provide a natural framework for modeling the competing incentives of electricity market participants. This thesis focuses on the use of learning, optimization, mechanism design, and preference elicitation methods to coordinate …

Autonomous agents for serving complex information needs
… novel paradigm for information service in which autonomous agents help dissatisfied users in web communities by proactively posting responses to their unresolved queries. The main contribution of this work is to concretely define three application tasks based on this paradigm in the healthcare …

Believable conversational agents for teaching ancient history and culture in 3D virtual worlds
This thesis introduces believable conversational agents as an engaging and motivational learning tool for teaching ancient history and culture in virtual worlds. Traditional approaches are lacking engagement, interactivity and socialisation, features that are of tremendous importance to modern …
