Balancing generality and specialization for machine learning in the post-ISA era
(Georgia Institute of Technology, 2019-03-29)
A growing number of commercial and enterprise systems are increasingly relying on compute-intensive machine learning algorithms. While the demand for these apaplications is growing, the performance benefits from general-purpose ...
Automated iterative game design
(Georgia Institute of Technology, 2016-12-06)
Computational systems to model aspects of iterative game design were proposed, encompassing: game generation, sampling behaviors in a game, analyzing game behaviors for patterns, and iteratively altering a game design. ...
Human-centered algorithms and ethical practices to understand deviant mental health behaviors in online communities
(Georgia Institute of Technology, 2019-07-19)
Social media has changed how individuals cope with health challenges in complex ways. In some mental health communities, individuals promote deliberate self-injury, disordered eating habits, and suicidal ideas as acceptable ...
Combinational machine learning creativity
(Georgia Institute of Technology, 2019-07-24)
Computational creativity is a field focused on the study and development of behaviors in computers an observer would deem creative. Traditionally, it has relied upon rules-based and search-based artificial intelligence. ...
Visual attribute labeling of images
(Georgia Institute of Technology, 2019-08-12)
In this work, we analyze and apply various recent techniques in visual attribute recognition and labeling on a common benchmark dataset in order to motivate the design of a novel framework for this task. Using the large ...
AI-infused security: Robust defense by bridging theory and practice
(Georgia Institute of Technology, 2019-09-20)
While Artificial Intelligence (AI) has tremendous potential as a defense against real-world cybersecurity threats, understanding the capabilities and robustness of AI remains a fundamental challenge. This dissertation ...
Visual question answering and beyond
(Georgia Institute of Technology, 2019-09-03)
In this dissertation, I propose and study a multi-modal Artificial Intelligence (AI) task called Visual Question Answering (VQA) -- given an image and a natural language question about the image (e.g., "What kind of store ...
Process-structure linkages with materials knowledge systems
(Georgia Institute of Technology, 2016-09-09)
The search for optimal manufacturing process routes that results in the combination of desired properties for any application is a highly dimensional optimization problem due to the hierarchical nature of material structure. ...
Evaluating visual conversational agents via cooperative human-AI games
(Georgia Institute of Technology, 2019-04-26)
As AI continues to advance, human-AI teams are inevitable. However, progress in AI is routinely measured in isolation, without a human in the loop. It is crucial to benchmark progress in AI, not just in isolation, but ...
Urban 3D scene understanding from images
(Georgia Institute of Technology, 2018-01-22)
Human vision is marvelous in obtaining a structured representation of complex dynamic scenes, such as spatial scene-layout, re-organization of the scene into its constituent objects, support of each object, etc. We also ...
