Flow Classification Using Clustering And Association Rule Mining
Flow Classification Using Clustering And Association Rule Mining

... The classification model is evaluated by the conventional machine learning metrics such as Precision, Recall and Accuracy [5]. The data set from a classification algorithm can be placed in a combination of the following categories - Positive and Negative. The following metrics are used as evaluation ...

In these models, it is usually assumed that the rate at a site is chosen i.i.d. from a given distribution. Such a “rates across sites” model is subtly different from a “variable site ...

Mixture model

In statistics, a mixture model is a probabilistic model for representing the presence of subpopulations within an overall population, without requiring that an observed data set should identify the sub-population to which an individual observation belongs. Formally a mixture model corresponds to the mixture distribution that represents the probability distribution of observations in the overall population. However, while problems associated with ""mixture distributions"" relate to deriving the properties of the overall population from those of the sub-populations, ""mixture models"" are used to make statistical inferences about the properties of the sub-populations given only observations on the pooled population, without sub-population identity information.Some ways of implementing mixture models involve steps that attribute postulated sub-population-identities to individual observations (or weights towards such sub-populations), in which case these can be regarded as types of unsupervised learning or clustering procedures. However not all inference procedures involve such steps.Mixture models should not be confused with models for compositional data, i.e., data whose components are constrained to sum to a constant value (1, 100%, etc.). However, compositional models can be thought of as mixture models, where members of the population are sampled at random. Conversely, mixture models can be thought of as compositional models, where the total size of the population has been normalized to 1.
