Clustered Naive Bayes
… In this thesis, I present the Clustered Naive Bayes classifier, a hierarchical extension of the classic Naive Bayes classifier that ties several distinct Naive Bayes classifiers by placing a Dirichlet Process prior over their parameters. A priori, the model assumes that there exists a …

Institutional theory of naive money
… how capital from unsophisticated investors (naive money) is associated with fund performance dynamics. In the framework, when naive money invested in a fund exceeds the ideal amount for the manager's skill, it leads funds to under-perform persistently. In contrast, the model predicts that, …

Masquerade detection using fortified naive Bayes
… Roy Maxion and Kevin Killourhy utilized a Naive Bayes classifier for detection using enriched Unix command lines, which are command line entries that still contain flags and other data. They discovered a problem with users that they dubbed supermasqueraders. These were users that would …

A Naive, Robust and Stable State Estimate
A naive approach to filtering for feedback control of dynamic systems that is robust and stable is proposed. Simulations are run on the filters presented to investigate the robustness properties of each filter. Each simulation with the comparison of the filters is carried out using the usual mean …

Causes of Naive Ethanol Avoidance in Drosophila Melanogaster
… a choice assay, the FRAPPE, to determine whether naive flies exhibited preference for 15% ethanol. To interfere with neuronal function, I used the Gal4/UAS system, which allows for tissue specific manipulation of the activity of both neurons and genes. RESULTS: On average, Drosophila flies ate …

Ontology-based annotation using naive Bayes and decision trees
… and model the annotations with a group of naive Bayes classifiers, then explore the inherent relationship among different components defined by the ontology using a probabilistic decision tree model. Our solution outperforms conventional text mining approaches by taking advantage of an …

Determining the Signalling Pathways that Govern Human Naive Pluripotency
… conditions are karyotypically normal, maintain a naive pluripotent transcriptional profile and exhibit reduced aberrant expression of mesodermal and endodermal lineage markers. I utilise the increased stringency of this culture system in combination with small molecule inhibitors to examine the …

Defining the essential regulators of naive human pluripotent stem cell reprogramming
Human pluripotent stem cells (PSCs) exist in two distinct states – naïve and primed, which are interconvertible. Naïve PSCs uniquely harbour several desirable properties that primed PSCs do not, including their ability to model human pre-implantation biology and developmentally-regulated epigenetic …

Modelling metabolic landscapes in human naive and primed embryonic stem cells
… pluripotent cells in culture which exist in a naive (more pluripotent) and a primed (epiblast like) state and show the same differences in metabolic regulation. These two cell states also show major differences in their epigenetic landscape including in DNA methylation, repressive histone …

Optimal versus naive diversification : do different loss functions improve portfolio choice?
I estimate the out-of-sample performance of the equal weight, minimum variance and mean-variance model portfolios in different settings. In each setting, I vary the loss function used when estimating returns and covariances, length of the estimation window, and number of factors used in our …

A study of the problems of man-computer dialogues for naive users
… for situations in which the 'man' is a 'naive' user i.e. a person without training or experience of computer procedures. Thus the aim of this project has been to produce a series of specialised guidelines for designers of dialogues for naive users. An examination of the literature reveals …

Contact-Dependent Activation of Macrophages by Naive CD4<sup>+</sup> T cells.
<p>Naive T cells are positioned at the origin of adaptive immune responses. The activation of naive T cells is usually viewed from the perspective of IL-2 production and entry into the cell cycle. This activation is antigen specific and MHC restricted via TCR ligation/CD3 signaling but also demands …

Responding Patterns of Naive Children and Adults to Artistic Styles in Paintings
… this thesis. More specifically, the ability of naive children and adults to use the visual information available in the works of five Impressionist painters and to identify painting style was explored.

Longest Common Subsequence Over Constant-Sized Alphabets: Beating the Naive Approximation Ratio
… gives the first nontrivial improvement over the naive 1/k approximation for the LCS of strings over alphabets of size k for all k ≥ 3.

Fault-injection through model checking via naive assumptions about state machine synchrony semantics
… with model checking. We introduce a concept of "naive assumptions" which exploits the assumptions of execution order, synchrony and fairness. "Naive assumptions" are applied to inject faults into our models. We use linear temporal logic to examine the model for anomalous behaviors. This method …

Effect of CDDO-me on Myelopoiesis in Naive Mice and Mice Undergoing Bone Marrow Transplantation (BMT)
To treat cancer and other hematological diseases, large numbers of hematopoietic stem cells (HSC) and hematopoietic progenitor cells (HPC) are needed. The objectives of this study were to examine the toxicity effect of the synthetic triterpenoid CDDO-me in vivo, to investigate the effect of CDDO-me …
