	Bayesian spam filtering - Wikipedia, the free encyclopedia
		Bayesian spam filtering is the process of using Bayesian statistical methods to classify documents into categories.
		For instance, Bayesian spam filters will typically have learned a very high spam probability for the words "Viagra" and "refinance", but a very low spam probability for words seen only in legitimate email, such as the names of friends and family members.
		There is recent speculation that even the brain uses Bayesian methods to classify sensory stimuli and decide on behavioural responses (Trends in Neuroscience, 27(12):712-9, 2004) (pdf).

	Bayesian Analysis of U.S. Hurricane Climate
		The approach is Bayesian, combining the reliable records of hurricane activity during the 20th century with the less precise accounts of activity during the 19th century, to produce a best estimate of the posterior distribution on the annual rates.
		The analysis shows that the number of major hurricanes expected to reach the U.S. coast over the next 30 years is 18, while the number of hurricanes expected to hit Florida is 20.
		Bayesian theory provides a framework to define a predictive hurricane climate that uses all the available records, and that can to be used as a benchmark against which future activity is gauged.

	An Introduction to Bayesian Networks and their Contemporary Applications
		Bayesian Networks are becoming an increasingly important area for research and application in the entire field of Artificial Intelligence.
		Bayesian networks are useful for both inferential exploration of previously undetermined relationships among variables as well as descriptions of these relationships upon discovery.
		Bayesian inference is useful because it allows the inference system to construct its own potential systems of meaning upon the data.

	Bayesian networks and significance of place (Site not responding. Last check: 2007-10-26)
		The spatial analysis of the Nazi party was conducted at the national scale in order to maximize the number of cases and, therefore, assist in facilitating the robustness of the Bayesian network created later.
		A drawback to the construction of Bayesian networks is the determination of its structure with respect to causality and dependence among the nodes.
		To determine the structure of a Bayesian network, two things are required: some order of the variables that indicates which variables are causes and which are effects, and an assessment of the subset of variables that are conditionally independent of one another.

	A Plan for Spam
		I thought I was being very clever, but I found that the Bayesian filter did the same thing for me, and moreover discovered of a lot of words I hadn't thought of.
		To beat Bayesian filters, it would not be enough for spammers to make their emails unique or to stop using individual naughty words.
		You could use a Bayesian filter to rate the site just as you would an email, and whatever was found on the site could be included in calculating the probability of the email being a spam.

	New View of Statistics: Confidence Limits (Site not responding. Last check: 2007-10-26)
		A Bayesian concludes (from the credibility limits of -1.0% to 3.2%) that the drug has anything from a marginal negative effect to a small positive effect.
		(Bayesians give their belief a complete probability distribution, but the principle is the same.) You could--and probably do--base the belief on the results of other studies, but you might just as well meta-analyze these other studies to get your prior "belief".
		Bayesian analysis may be justified where a decision has to be made with limited real data.

	Weibull-Bayesian Analysis
		In this section, the Bayesian methods are presented for the two-parameter Weibull distribution.
		Bayesian concepts were introduced in the Statistical Background chapter.
		The procedure for obtaining other points of the posterior distribution is similar to the one for obtaining the median values, where instead of 0.5 the percentage of interest is given.

	Bayesian Epistemology
		Bayesians propose additional standards of synchronic coherence — standards of probabilistic coherence — and additional rules of inference — probabilistic rules of inference — in both cases, to apply not to beliefs, but degrees of belief (degrees of confidence).
		What unifies Bayesian epistemology is a conviction that conditionalizing (perhaps of a generalized sort) is rationally required in some important contexts — that is, that some sort of conditionalization principle is an important principle governing rational changes in degrees of belief.
		On a Bayesian account, the effect of evidence E in confirming (or disconfirming) a hypothesis is solely a function of the increase in probability that accrues to E when it is first determined to be true.

	Bayesian filter - a definition from Whatis.com
		A Bayesian filter is a program that uses Bayesian logic, also called Bayesian analysis, to evaluate the header and content of an incoming e-mail message and determine the probability that it constitutes spam.
		Bayesian logic is an extension of the work of the 18th-century English mathematician Thomas Bayes.
		Bayesian filters aren't perfect, but because spam characteristically contains certain types of text, such a program can be amazingly effective when it is fine-tuned over a period of time.

	Applied Bayesian Statistics
		By the end of the term, you should be in a position to extend the Bayesian approach in a wide assortment of directions that you can tailor to your own interests.
		Students will be expected to write a fully Bayesian research paper where they apply a technique that they learned in class to a research question that interests them.
		Miracles are not expected—a Bayesian multiple regression would be more than adequate, especially since you may run into computational problems beyond the purview of the class with more sophisticated applications.

	Graphical Models (Site not responding. Last check: 2007-10-26)
		The simplest conditional independence relationship encoded in a Bayesian network can be stated as follows: a node is independent of its ancestors given its parents, where the ancestor/parent relationship is with respect to some fixed topological ordering of the nodes.
		Note that "temporal Bayesian network" would be a better name than "dynamic Bayesian network", since it is assumed that the model structure does not change, but the term DBN has become entrenched.
		The standard approach in the reconstructibility analysis (RA) community uses the fact that \chi^2(X,Y) \approx I(X,Y) N \ln(4), where N is the number of samples and I(X,Y) is the mutual information (MI) between X and Y. Hence we can use a \chi^2 test to decide whether an increase in the MI score is statistically significant.

	Better Bayesian Filtering
		Spam filtering is a subset of text classification, which is a well established field, but the first papers about Bayesian spam filtering per se seem to have been two given at the same conference in 1998, one by Pantel and Lin [2], and another by a group from Microsoft Research [3].
		So their numbers may not even be an accurate measure of the performance of their algorithm, let alone of Bayesian spam filtering in general.
		If you were doing Bayesian filtering in a situation where the ratio of spam to nonspam was consistently very high or (especially) very low, you could probably improve filter performance by incorporating prior probabilities.

	Bayesian bootstrap for proportional hazards models, Yongdai Kim, Jaeyong Lee
		The binomial form Bayesian bootstrap is the limit of the posterior distribution with a beta process prior as the amount of the prior information vanishes, and thus can be considered as a default nonparametric Bayesian analysis.
		The Poisson form Bayesian bootstrap is equivalent to the Bayesian analysis with Cox's profile likelihood.
		Finally, it is shown that both Bayesian bootstrap posteriors are asymptotically equivalent to the sampling distribution of the maximum likelihood estimator.

	Bayesian logic - a definition from Whatis.com
		Named for Thomas Bayes, an English clergyman and mathematician, Bayesian logic is a branch of logic applied to decision making and inferential statistics that deals with probability inference: using the knowledge of prior events to predict future events.
		The International Society for Bayesian Analysis (ISBA) was founded in 1992 with the purpose of promoting the application of Bayesian methods to problems in diverse industries and government, as well as throughout the Sciences.
		The modern incarnation of Bayesian logic has evolved beyond Bayes' initial theorem, developed further by the 18th century French theorist Pierre-Simon de Laplace, and 20th and 21st century practitioners such as Edwin Jaynes, Larry Bretthorst, and Tom Loredo.

	Bayesian Analysis (Site not responding. Last check: 2007-10-26)
		The "Bayesian method" is based on the Bayesian theorem which suggests that the degree to which one believes that a propositioon is true depends on on the a priori belief which one has in the truth of the proposition and in the evidence collected to to investigate the proposition.

		To that end, we introduce a Bayesian analysis of gene expression level (BAGEL) model for statistical inference of gene expression and demonstrate its utility by re-examining cDNA microarray data on the response of yeast to ethanol shock [11], on transcriptional regulation by SNF2 and SWI1 [12], and on zinc regulation [13].
		For instance, BAGEL analysis of the zinc-regulation data revealed 96 genes whose levels of gene expression in a wild-type genotype and zinc-deficient medium were significantly greater than both zinc-supplemented wild-type and zap1 in zinc-deficient medium.
		A hierarchical Bayesian model [34] has been used to analyze ratio data and provide 95% confidence intervals for the log ratio of gene expression from reference to control.
