Dynamic Pairwise Sparse Tuning (Dpst) Vs. Static Two-Predictor Selection: A Neural Network Approach, Raymond Dacosta Azadda

Mathematics and Statistics

Identifying two active predictors driving a response variable is critical in fields like genomics, medicine, and finance, yet standard methods, such as penalized regression, often fail to isolate these pairs consistently. We propose Dynamic Pairwise Sparse Tuning (DPST), a novel feedforward neural network (FNN) method that enhances sparse predictor selection by augmenting standard backpropagation with custom weight updates using adaptive thresholding, smoothed refinement, and pruning. Through simulations across predictor counts (P = 3, 4, 5) and sample sizes (N = 1800, 3600) using a controlled sparse coefficient matrix defining pair relationships, DPST consistently outperforms our static FNN baseline, also developed …

Modeling The Effects Of Socioeconomic And Environmental Factors On Child Malnutrition And Contamination Risk Using Generalized Estimating Equations, Samuel Amoateng

Pharmacy and Wellness Review

Treatment-resistant depression (TRD) is a challenging and possibly life-threatening condition that affects millions of people worldwide. Patients with major depressive disorder (MDD) are diagnosed with TRD once they have tried and failed to respond to two antidepressant treatments at the maximum dose for a full trial of six to eight weeks. Most traditional antidepressant therapies work by increasing the levels of monoamine neurotransmitters such as dopamine, serotonin, and norepinephrine in the brain. These medications have a delayed onset of action, ranging from two to eight weeks, and often fail to relieve depressive symptoms in a patient with TRD. Therefore, targeting …

Guidelines For The Creation And Implementation Of A School-Based Vision Program For The Greater Seattle Area, Suzanna P. Gill

Honors Projects

Proper vision care contributes to a child’s ability to perform academically as well as their overall health and wellbeing. Pediatric vision care begins with vision screening, which occurs in public schools in Washington state. These vision screenings allow for possible vision issues to be identified in children. They are not, however, a replacement for eye examinations that help determine what is causing the problem and provide treatment. A substantial proportion of children that are recommended to receive the exams will not, partially because Washington does not require parents to take their children to eye care professionals. These children are more …

The identification of causal genomic regions for liver fat accumulation in the context of metabolic dysfunction remains a challenging goal. This study aimed to identify potential endophenotypes for liver fat content and employ them in bivariate linkage searches for pleiotropic genetic regions where targeted association analysis is more likely to reveal significant variants. Multiple metabolic risk and adiposity distribution traits were assessed using the endophenotype ranking value. The top-ranked endophenotypes were then used in a bivariate linkage analysis, paired with liver fat content. Quantitative trait loci (QTLs) identified as significant or suggestive were targeted for measured genotype association analyses. The …

Worship Through Miniature Gesture: The Tell Asmar Hoard As Ritual Role Models, Libby Bush

Art History Theses and Dissertations

This thesis argues for a new approach to hand gesture in the Early Dynastic period, and more broadly, the Ancient Near East. I use the Tell Asmar hoard, a group of twelve miniature sculptures that were found buried in a temple in ancient Eshnunna in the Diyala region of Iraq, as a case study. The sculptures are dated to the Early Dynastic (2900-2334 BCE) and belong to the larger corpus of sculptures of Mesopotamia. I argue that the Tell Asmar hoard act as role models and mediators for the temple worshiper. My argument is built upon miniaturization theory, as the …
