Group testing for image compression
This thesis studies the application of group testing to image compression. Group testing is a technique used for identifying a few significant items out of a large set. Image compression studies techniques for making image data take up less storage space. We first explain the many interesting and …

Topics in Heterogeneous Group Testing
<p>DISS_abstract> Since the early 1940s, group testing has been widely used to reduce costs in a variety of applications, including infectious disease screening, drug discovery, and genetics. Statistical research in group testing generally splits into two areas: classification and estimation. …

On Privacy in Group Testing
Group testing is a method of designing collections of samples of individual items and assessing them as collections (rather than individuals) with the goal of revealing individuals who are positive for some attribute. It has been used to test for highly contagious diseases, such as coronavirus in …

New group testing paradigms: from practice to theory
We propose a novel group testing framework, termed semi-quantitative group testing, motivated by a class of problems arising in genome screening experiments in addition to other applications such as interpretable rule learning for decision making. Semi-quantitative group testing (SQGT) is a …

Improved upper bounds for several variants of group testing
Group testing is a class of search problems, in which we aim to identify all of n items as either good or defective. We may perform tests on arbitrary subsets, which indicate whether the tested group contains only good items or at least one defective. In the (d,n) and generalized (d,n) group …

Biological applications for de Bruijn subgraphs and interval group testing
… more theoretical, presents a study on Interval Group Testing in the presence of erroneous test outcomes. Although the subjects of both parts are from the computational viewpoint completely distinct, their motivations are closely related: while the study of de Bruijn subgraphs was motivated by …

Edge search in graphs using incidence tests
In this work we consider the $(2,n)$ group testing problem with test sets of cardinality at most $p$. We present sharp upper and lower bounds for the worst case number $c_p(2,n)$ of tests for this group testing problem and show that the maximum difference between the upper and lower bounds is 3. …

Optimal Risk-based Pooled Testing in Public Health Screening, with Equity and Robustness Considerations
Group (pooled) testing, i.e., testing multiple subjects simultaneously with a single test, is essential for classifying a large population of subjects as positive or negative for a binary characteristic (e.g., presence of a disease, genetic disorder, or a product defect). While group testing is …

Inference and Diffusion in Networks
… Inference, which focuses on estimation, testing, and uncertainty quantification, provides the mathematical tools to learn from data rigorously. This thesis utilizes both theory and data in order to address several real-world challenges. In the first chapter, we study epidemic spread and …

Algorithmic advances in learning from large dimensional matrices and scientific data
… coding scheme perform exceptionally well for the group testing problem. Lastly, we present a novel machine learning application for coding theory, that of solving large scale multilabel classification problems. We propose a new algorithm for multilabel classification which is based on group …

Forensic analysis of unallocated space
… tree indexing for fast searching. We also apply group testing to identify the fragmentation point of the file and locate the starting cluster of each fragment based on statistics on the gap between the fragments. Furthermore, in order to retrieve evidence and clues from unallocated space by …

Efficient Prevalence Estimation for Emerging and Seasonal Diseases Under Limited Resources
… planning of healthcare services. Due to limited testing budgets and resources, prevalence estimation typically entails pooled, or group, testing where specimens (e.g., blood, urine, tissue swabs) from a number of subjects are combined into a testing pool, which is then tested via a single test. …

Values and Academic Achievement among Rural Indian High School Students in North Dakota
… teachers from seven schools were surveyed in group testing sessions. All subjects completed questionnaires eliciting personal information, character trait preferences, and perceptions of themselves, ideal self, and others. Students completed two additional self-esteem measures. Relevant …

Approximate Message Passing for Matrix Regression
… model to the pooled data and the quantitative group testing (QGT) problem, where the design matrix is binary-valued. For the noiseless pooled data setting, we show that the studied AMP algorithm is equivalent to one recently proposed by El Alaoui et al. Our results provide a rigorous version of …

Alleviating Stress in Clergy Wives: The Development and Formative Evaluation of a Psychoeducational Group Intervention
… Wife Wings (CWW), a 5-session psychoeducational group plan for 6 to 10 clergy wives, to alleviate ministry-related stress and (b) the formative evaluation of the plan in its first implementation. Conclusions drawn suggested that CWW showed good potential as an intervention in helping clergy wives …

The Impact of the Vocational Assessment Process on Juvenile Offender Self Concept

The relationship between social anxiety and alcohol consumption in college students: Scale development, construct validation, and testing of a social cognitive model
… in socially anxious college students. Using group testing and individual interview formats questionnaires assessing alcohol expectancies of improved sociability and self-efficacy were developed and shown to have adequate levels of reliability and construct validity. These questionnaires, …

Spatial Coupling for High-Dimensional Estimation
… sensing matrices and apply them to quantitative group testing and pooled data testing. In both cases, we show that AMP achieves almost-exact recovery of a linear number of defectives from a sublinear number of tests. The performance of these spatially coupled AMP algorithms surpasses that of …

An investigation of laying hen interactions with ammoniated environments by means of preference testing
