Graphical methods in prior elicitation.
Prior elicitation is the process of quantifying an expert's belief in the form of a probability distribution on a parameter(s) to be used in a Bayesian data analysis. Existing methods require experts to quantify their belief by specifying multiple distribution summaries, which are then converted …

Prior information for brain parcellation
… of problems. This framework employs anatomical prior information in order to simplify the detection process. In this thesis, we experiment with different types of prior information such as spatial priors, shape models, and trees describing hierarchical anatomical relationships. We pose a maximum …

Phase Retrieval Under a Generative Prior
… the problem requires additional assumptions, or priors, on its structure in order to guarantee recovery. Many techniques enforce a sparsity prior, meaning that the signal has very few non-zero entries. However, these methods have seen various computational bottlenecks. We sidestep this issue by …

Autonomous Navigation without HD Prior Maps
… systems currently rely on High Definition (HD) prior maps both to localize, and to retrieve detailed geometric and semantic information about the environment. This information is necessary to enable safe operation of many downstream driving components including, prediction, planning, and …

Prior Pidginization and Creolization in Moroccan Arabic
This thesis makes a claim about the processes of prior pidginization and creolization, and a process of current decreolization in Moroccan Arabic (a colloquial dialect of Arabic spoken in Morocco). The claim of this thesis is based on the theory of pidginization and creolization in Arabic as …

Novice Teachers Perceptions of Prior Mentoring Experiences
<p>More than 50% of novice educators leave the profession in the first 5 years of service. Novice educators were defined as educators with 5 or fewer years of teaching experience. The State of Tennessee has estimated the cost for that decision to around $28,000.00 per teacher for each local …

Alignability and Prior Knowledge in Category Learning
… with the roles of structural alignment and prior knowledge in category learning. Structural alignment (Gentner, 1983, 1989) is a theory that claims that similarity comparisons entail a process of aligning the components of the things being compared, determining what corresponds to what. The …

Prior Knowledge and Reading Comprehension Test Bias
… examined bias, especially that due to prior knowledge, in tests of reading comprehension. A pilot study demonstrated that prior knowledge has a strong and measurable effect on comprehension from expository text, even when measured with multiple choice questions. This was demonstrated in …

Surface Prior Information Reflectance Estimation (SPIRE) algorithms
… approaches, we assumed the presence of a prior reflectance image cube and ensembles of typical multiplicative and additive illumination noise vectors, and developed algorithms which estimate reflectance using this prior information. These algorithms were developed under the additional …

Improving prior knowledge assessment in process characterization
… intensive, both human and capital, so leveraging prior knowledge from previous experiments is essential. Until now, using data from past experiments data relied on a centralized static document called Prior Knowledge Assessment (PKA). The PKA aggregates the results of many statistical models that …

Measuring organisational readiness prior to IT/IS investment
… which don't address organisational readiness prior to IT/ISinvestment. This PhD study has developed a holistic model to measure the capabilityorganisations to 'successfully' implement IT by measuring their readiness status toimplement new IT/IS systems, prior to IT/IS investment. The model is …

Prior Information Guided Image Processing and Compressive Sensing
… models if the given data lacks some certainties. Prior information, including geometric priors, high frequency priors, spatially variant intensity variations and image regularities, assists to establish mathematical models by providing a more accurate description of the underlying signal/image. We …

3D Non-Rigid Reconstruction with Prior Shape Constraints
… based on both the observations and the prior learned manifold. Firstly, an incremental approach is proposed for estimating the deformable objects. An important advantage of this method is the ability to reconstruct the 3D shape from a newly observed image and update the parameters in 3D …

The effect of prior exercise on postprandial lipaemia
… chapters within this thesis are that: prior moderate exercise reduces the lipaemia associated with moderate and high fat meals to a very similar extent in percentage terms; a single session of resistance exercise does not lower postprandial TAG concentrations in overweight, sedentary …

Model sensitivity to prior selection in replication studies
… Analysis for a replication study, selecting priors is a widely discussed issue. On one hand, we could argue that an informative prior specified by previous research is preferable because we have some knowledge and expectations regarding the phenomena. However, when the goal is to replicate …
