Jang, Bum Soon (2009-05-15)Networks, and associative properties, prevalent in natural and artificial systems have been investigated extensively. A common method for network analysis is based on graph theory because graphs naturally represent the ...
-
Titriku, Alex K (2014-12-04)The past decade has seen a significant amount of academic and industrial research into interconnect topologies that employ optical channels for next generation high speed communication systems. Integrated optical interconnects ...
-
Niu, Wei (2017-12-04)The global sharing of fine-grained geo-spatial footprints – via smart mobile devices and social media services (e.g., Facebook, Twitter, Flickr) – is leading to the creation of a new class of geo-social systems. These ...
-
Li, Youjie (2016-04-27)There is a growing concern over reliability, power consumption, and performance of traditional Von Neumann machines, especially when dealing with complex tasks like pattern recognition. In contrast, the human brain can ...

Enhanced Reinforcement Learning with Attentional Feedback and Temporally Attenuated Distal Rewards Thulasiraman, Kumaran (2015-08-09)This thesis presents a new reinforcement learning mechanism suitable to be employed in artificial spiking neural networks of leaky integrate-and-fire (LIF) or Izhikevich neurons. The proposed mechanism is upgraded from, ...
-
Sunder, Gowrishankar (2015-05-07)Error Correction has applications in a variety of domains given the prevalence of errors of various kinds and the need to programmatically correct them as accurately as possible. For example, error correction is used in ...
-
Mueller, William Graham (2012-10-19)This dissertation contains two essays which examine the roles that individual incentives, competition, and information play in network formation. In the first essay, I examine a model in which two competing groups offer ...
-
Lee, Sang Han (2009-05-15)The objective of this dissertation is to develop a suitable statistical methodology for functional data analysis. Modern advanced technology allows researchers to collect samples as functional which means the ideal unit ...
-
Chung, Ji Ryang (2012-07-16)In the neuronal circuits of natural and artificial agents, memory is usually implemented with recurrent connections, since recurrence allows past agent state to affect the present, on-going behavior. Here, an interesting ...
-
Li, Qinbo (2022-05-03)Humans are good at using multimodal information to perceive and to interact with the world. Such information includes visual, auditory, kinesthetic, etc. Despite the advancement in deep learning using single modality in ...
-
Sung, Chul (2014-04-25)Advances in high-throughput, high-volume microscopy techniques have enabled the acquisition of extremely detailed anatomical structures on human or animal organs. The Knife-Edge Scanning Microscope (KESM) is one of the ...
-
Lee, Hyun Soo (2011-10-21)This dissertation investigates the extraction of knowledge from a known environment. Virtual ontology – the extracted knowledge – is defined as a structure of a virtual environment with semantics. While many existing 3D ...
-
Lim, Hee Jin (2009-06-02)Neural conduction delay is a serious issue for organisms that need to act in real time. Perceptual phenomena such as the flash-lag effect (FLE, where the position of a moving object is perceived to be ahead of a brief flash ...
-
Okyere, Jeffrey Kwabena (2017-01-04)Modern wireless applications require access to ultra-wide instantaneous RF bandwidths to provide frequency agility and multi-band RF processing. Wireless communications, radar and electronic warfare are examples of ...
-
Kim, Hong-Hoe (2016-05-05)Children’s self-regulation skills predict their school-readiness and social behaviors, and assessing these skills enables parents and teachers to target areas for improvement or prepare children to enter school ready to ...
-
Jiraraksopakun, Yuttapong (2010-07-14)A complex and challenging problem in flow study is to obtain quantitative flow information in opaque systems, for example, blood flow in biological systems and flow channels in chemical reactors. In this regard, MRI is ...
-
Sarmiento, Traci Ann (2017-07-26)This dissertation research shows a small unmanned rotorcraft system with onboard processing and a vision sensor can produce autonomous, collision-free flight in a restricted maneuverability environment with no a priori ...
-
Zhao, Guanlong (2020-06-22)Foreign accent conversion (FAC) aims to generate a synthetic voice that has the voice identity of a given non-native speaker (NNS), but the pronunciation patterns (i.e., accent) of a native speaker (NS). This synthetic ...
-
Dobreva, Iliyana D. (2010-07-14)Accurate areal measurements of snow-cover extent are important for hydrological and climate modeling. The traditional method of mapping snow cover is binary where a pixel is approximated to either snow-covered or snow-free. ...
