Information theoretic approach to quantization and classification for signal processing, communications, and machine learning applications

Creator:: Thuan Nguyen D.
Abstract:: There are five main contributions of this dissertation. The first contribution is new closed-form expressions for channel capacity of a new class of channel matrices. The second contribution is the discovery of the structure for optimal binary quantizer and the associated methods for finding an optimal quantizer that maximizes mutual...

Part-based and Uncertainty-Aware Few-shot Object Segmentation in Images

Creator:: Nguyen, Khoi D.
Abstract:: This dissertation addresses few-shot object segmentation in images. The goal of segmentation is to label every image pixel with a class of the object occupying that pixel, where the class may represent a semantic object category or instance. In few-shot segmentation, training and test datasets have different classes. Every new...

Convergence Analysis Framework for Fixed-Point Algorithms in Machine Learning and Signal Processing

Creator:: Vu, Trung
Abstract:: Iterative algorithms are simple yet efficient in solving large-scale optimization problems in practice. With a surge in the amount of data in past decades, these methods have become increasingly important in many application areas including matrix/tensor recovery, deep learning, data mining, and reinforcement learning. To optimize or improve iterative algorithms,...

Exploring Southeast Asian American Women in Community College Leadership: A Narrative and Life Story Study

Creator:: Vu, Emily P. T.
Abstract:: Background: The numbers of Southeast Asian women in higher education, whether within administration, teaching faculty, or counseling and student services are scarce. The specific needs of minority women go largely unnoticed and remain unaddressed and may contribute to the low numbers of minority women in higher education leadership. Purpose: The...

Multiagent Learning via Dynamic Skill Selection

Creator:: Sachdeva, Enna
Abstract:: Multiagent coordination has many real-world applications such as self-driving cars, inventory management, search and rescue, package delivery, traﬃc management, warehouse management, and transportation. These tasks are generally character-ized by a global team objective that is often temporally sparse - realized only upon completing an episode. The sparsity of the shared...

Visual object discovery and understanding

Creator:: Yuan, Jialin
Abstract:: Learning to recognize objects is a fundamental and essential step in human perception and understanding of the world. Accordingly, research of object discovery across diverse modalities plays a pivotal role in the context of computer vision. This field not only contributes significantly to enhancing our understanding of visual information but...

Climate-Smart Aquaculture: A Conceptual Framework for Evaluating Air-Breathing Fish for Sustainable Food Systems

Creator:: Ichien, Stephanie T.
Abstract:: The global demand for food is expected to double by 2050, presenting a need that is complicated by the many interrelated of pressures on the world’s natural resources from climate change, growing urban populations, and increasing development. As one of the fastest growing food production sectors, aquaculture is poised to...

Evaluating the Dietary Toxicity of Per- and Polyfluoroalkyl Substances and Development of a High Throughput Non-Invasive Zebrafish Cortisol Assay

Creator:: Leong, Connor A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are contaminants of concern because they do not readily degrade in the environment. Some in vivo studies report that PFAS alter neurological development and are carcinogenic. Perfluorohexanesulfonamide (FHxSA) and 6:2 fluorotelomer sulfonate (6:2 FTS) are two PFASs, which are often detected in drinking water sources....

A Novel CCRW Receiver with Variable Width Window for Mitigating Multipath and Ambiguity in GNSS Positioning

Creator:: Alhussein, Fahad
Abstract:: This work presents a novel CCRW receiver that utilizes a window of variable width, for e˙ectively mitigating multipath and ambiguity in both civil and military positioning applica-tions using Global Navigation Satellite Systems (GNSS). This CCRW receiver incorporates a single stroboscopic window, whose width is iteratively reduced until the e˙ect of...

Per- and Polyfluoroalkyl Substances (PFAS) in Environmental Air-Water Matrices and Light Non-Aqueous Phase Liquids (LNAPL)

Creator:: Schwichtenberg, Trever J.
Abstract:: The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...
