... After doing these we formed 6 sets of feature-subsets (decision factors): Set1 contained 1 over 7, that is 7 subsets, each with one (distinct) features in it. Set2 contained 2 over 7 that is 21 subsets, each subset with 2 features in it,…, Sk contained k over 7 subsets, each with k elements in it (1 ...

... To get around these obstacles, one proposal is to characterize network traffic based on features of the transport-layer statistics irrespective of port-based identification or payload content. The idea here is that different applications on the network will exhibit different patterns of behavior wh ...

An Efficient Approach to Clustering in Large Multimedia
... Let us rst consider the locality-based clustering algorithm DBSCAN. Using a square wave in uence function with =EPS and an outlier-bound =MinPts, the abitary-shape clusters dened by our method (c.f. denition 5) are the same as the clusters found by DBSCAN. The reason is that in case of the sq ...

Expectation–maximization algorithm

In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
