Computational auditory saliency
… these salient sounds, we have developed a computational auditory saliency model inspired by our understanding of the human auditory system and auditory perception. By identifying salient sounds we can obtain a better understanding of how sounds are processed by the auditory system, and in …

Effective Computational Cosmology
… work investigates how the use of both EFTs and computational tools can help us to advance our knowledge of how the universe evolved and formed over time. Specifically, we review the successful EFT of Inflation, the EFT of Dark Energy (EFTDE), and introduce the EFT of Reheating as a generalized …

Computational information design
… together as part of a singular process titled Computational Information Design. This dissertation first examines the individual pedagogies of design, information, and computation with a focus on how they support one another as parts of a combined methodology for the exploration, analysis, and …

Computational immersive displays
… of ever-escalating hardware requirements and computational budgets. But what if one could increase a participant's sense of immersion, instead, by taking advantage of perceptual cues, neuroprocessing, and emotional engagement while adding only a small, yet distinctly targeted, set of …

Computational metric embeddings
We study the problem of computing a low-distortion embedding between two metric spaces. More precisely given an input metric space M we are interested in computing in polynomial time an embedding into a host space M' with minimum multiplicative distortion. This problem arises naturally in many …

Computational visual reality
It is not so far-fetched to envision a future student working through a difficult physics problem by using their hands to manipulate a 3D visualization that floats above the desk. A doctor preparing for heart surgery will rehearse on a photo-real replica of his patient's organ. A visitor to the …

Computational chunking in Chess
Adriaan de Groot, the Dutch psychologist and chess Master, argued that “perception and memory are more important differentiators of chess expertise than the ability to look ahead in selecting a chess move” (Groot 1978). A component of expertise in chess has been attributed to the expert having …
