Vamos a resolver: Collaboratively configuring the internet in Havana
(Georgia Institute of Technology, 2019-07-08)
Globally, nearly four billion people do not have access to the world wide web (WWW), and efforts to expand WWW access are growing rapidly. Despite these initiatives, local and international barriers along political, economic, ...
Automated support for improving software quality of mobile applications before and after release
(Georgia Institute of Technology, 2019-07-16)
Mobile devices are becoming the platform of choice for a number of tasks, including news consumption, online shopping, and streaming content. Mobile applications (or simply apps) play an essential role in the success of ...
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 ...
Improvisational artificial intelligence for embodied co-creativity
(Georgia Institute of Technology, 2019-08-14)
This dissertation explores embodied agents that can improvise with people in an object-based gestural proto-narrative domain. I study the improvisational action selection problem (the challenge of performing action selection ...
Probabilistic techniques for analyzing sampling algorithms and the dynamics of lattice models
(Georgia Institute of Technology, 2019-11-11)
Statistical mechanics bridges the fields of physics and probability theory, providing critical insights into both disciplines. Statistical physics models capture key features of macroscopic phenomena and consist of a set ...
Efficient and refinable attack investigation
(Georgia Institute of Technology, 2019-10-04)
As modern attacks become more stealthy and persistent, detecting or preventing them at their early stages becomes virtually impossible. Instead, an attack investigation or provenance system aims to continuously monitor and ...
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 ...
Improving in-house testing using field execution data
(Georgia Institute of Technology, 2019-08-14)
Software testing is today the most widely used approach for assessing and improving software quality. Despite its popularity, however, software testing has a number of inherent limitations. First, due to resource limitations, ...
Inference of structural brain networks and modeling of cortical multi-sensory integration
(Georgia Institute of Technology, 2019-11-12)
Recent advances in neuroimaging have enabled major progress in the field of brain connectomics, i.e., constructing maps of connections between brain regions at different scales. Diffusion MRI (dMRI) and probabilistic ...
Map-centric visual data association across seasons in a natural environment
(Georgia Institute of Technology, 2019-11-01)
Vision is one of the primary sensory modalities of animals and robots, yet among robots it still has limited power in natural environments. Dynamic processes of Nature continuously change how an environment looks, which ...
