Summary In this paper, we analysed classification rules under Bayesian decision theory. The setup we considered here is fairly general, which can represent all possible parametric models. The Bayes classification rule we investigated minimises the Bayes risk under general loss functions. Among the ...
1 Introduction Although Bayesian methods have been studied for many years, it is only recently that their practical application has become truly widespread. This is due in large part to the relatively high computational overhead of performing the marginalizations (integrations and summa- tions) which...
Naïve Bayesian classification is a supervised learning technique and a statistical classification method. Bayes theorem is used in decision-making and uses the knowledge of prior events to predict future events. (1.5)P(i|j)=P(j|i)∗P(i)/P(j) Eq. (1.5) states that the probability of...
The Bayesian spatial generalized linear (mixed) model offers a tool to accommodate both spatial and covariate sources of information in classification problems. In this paper, we formally define spatial classification rules based on these models in order to provide a principled empirical comparison to ...
Bayesian belief networks:ABayesianBelief Network is illustrated as adirected graph. Nodes show variables and the probability of the variables to take a specific value. Between the variables a cause-effect relationship exist. On the top a node for productivity is shown. The productivity can be defi...
as a fantasy animal and a dragon. Our Bayesian Aggregation algorithm, using the results of the kNN classifiers, produces a more accurate prediction for the flying_bird class, resolves the inconsistency with the flying_creature class, and rules out ...

5.601 (June 26, 2007) Preface Most of researches agree that kingdom-level classification of living things needs the special rules and principles. Two approaches are possible: (a) tree- based, Hennigian approach will look for main dichotomies inside so-called "Tree of Life"; and (b) space-...
(Atallah, Lo, King, & Yang, 2011) present a framework investigating on the sensor placement and the corresponding relevance for activity recognition. They use kNN with different values of k to assess the effect of outlier points and aBayesian classifierto model the data. (Janidarmian, Roshan ...
When operating a network, it may be necessary to specify rules and policies about the traffic that is carried in the network. For example, traffic that comes from a particular IP prefix may be treated differently than other traffic. Thus, traffic rules can be specified using the 5-tuple for...
