Self-Assessment And Robust Anomaly Detection With Bayesian Deep Learning, Giuseppina Carannante, Dimah Dera, Orune Aminul, Nidhal Bouaynaya, Ghulam Rasool

Electrical and Computer Engineering Faculty Publications

Deep Learning (DL) models have achieved or even surpassed human-level accuracy in several areas, including computer vision and pattern recognition. The state-of-art performance of DL models has raised the interest in using them in real-world applications, such as disease diagnosis and clinical decision support systems. However, the challenge remains the lack of trustworthiness and reliability of these DL models. The detection of incorrect decisions or flagging suspicious input samples is essential for the reliability of machine learning models. Uncertainty estimation in the output decision is a key component in establishing the trustworthiness and reliability of these models. In this work, …

Can You See Me, Or Can You Smell Me? An Investigation Into Information Transfer In Betta Splendens, Alex Daniel Lynch Jan 2022

Can You See Me, Or Can You Smell Me? An Investigation Into Information Transfer In Betta Splendens, Alex Daniel Lynch

School of Biological and Marine Sciences Theses

Visual communication in Betta splendens has been studied in great detail. Chemical information transfer in this species has been studied less, and the interaction between chemical and visual information transfer less still. Betta may have a need for chemical information transfer; a need which is often neglected when housing this species in isolation from conspecifics. There is evidence that many fish species communicate using visual signals and spy on one another using chemical cues. Which type of information transfer is important and how they interact in which social context is less clear. Eavesdropping and mate choice has been studied extensively …

A Step Towards Automating Real-Time Collection Of Ecological Data On Observational Platforms : A Pilot Study On Deep-Sea Benthic Species Syringammina Fragilissima, Erin Browne Jan 2022

A Step Towards Automating Real-Time Collection Of Ecological Data On Observational Platforms : A Pilot Study On Deep-Sea Benthic Species Syringammina Fragilissima, Erin Browne

School of Biological and Marine Sciences Theses

Despite current efforts to study deep-sea life, there is a dependency on technological advancements to asses it at a scale and pace required to inform effective management and conservation. Data collection platforms, such as Remotely Operated Vehicles (ROVs) are routinely applied to studying the deep sea due to their ability to collect large image-based datasets. Thus, data collection in the deep sea is becoming less of a problem in comparison to data interpretation, where terabytes of video data is collected during expeditions and manual interpretation of this is currently the standard procedure. Deep learning (DL), a sub-field of artificial intelligence …

Nonpharmacological Pain Control Following Hip And Knee Replacements In Older Adults, Adraine Cox

Walden Dissertations and Doctoral Studies

Abstract Over prescribing opioids after hip and knee replacements in older adults is closely linked to the opioid epidemic. Despite being a public health concern associated with increased mortality rates, opioids are the most frequently used method for controlling postoperative pain. Therefore is important to know whether nonpharmacological pain control methods may effectively reduce the burden of opioid addiction, thus reducing the risk of opioid-related fatalities. The purpose of this study was to determine whether a systematic review of the literature provided evidence supporting nonpharmacological methods of pain control following hip and knee replacements in older adults compared to use …

Coherence-Based Resilience Effects On Antenatal Autonomic Nervous System Stress Markers Controlled, Patrice Fortune

Walden Dissertations and Doctoral Studies

AbstractAntenatal stress disrupts autonomic nervous system (ANS) equilibrium within the neuro-cardio-utero-placental (NCUP) structure perpetuating treatable conditions of depressive-based gestational hypertension disorders. The present ANS-based study of the NCUP system investigated the effect of coherence-based stress resilience (CBSR) post-4-week intervention. This quasi-experimental research design involved experimental (n = 8) and waitlist control (n = 3) conditions. Controlling for pretest values, quantitative pre-post methodology was used to assess the effect of CBSR to evaluate change in variables. Resultant of small sample size, significant findings are considered tentatively. Heart rate variability (p = 0.044), dehydroepiandrosterone/ dehydroepiandrosterone sulfate (p = 0.142), Pregnancy Experience Scale …
