Experimental work on Data Clustering using Enhanced Random K-Mode Algorithm S. Sathappan
... In the real world, data mining applications are affected by data‟s uncertainty. All clustering algorithms aim of dividing the collection all data objects into subsets or similar clusters. A cluster is a collection of objects which are „similar‟ between them and are „dissimilar‟ to the objects belong ...

Partial-Sums Addition for Decimals
... As you work through Example 1 on page 17, point out that the partial sums should be written with the same number of decimal places as the addend with the greater (or greatest) number of decimal places. Use questions like the following to guide students through the examples: • Does it matter which pl ...

... This means that, by the Second Derivative Test, the function has a local maximum at (0, −2) and the local maximum value f (0, −2) = 4e−2 . The point (0, 0) is a saddle point. Find the absolute maximum and minimum values of f on the set D. 30. f (x, y) = 3+xy−x−2y, D is the closed triangular region w ...

Optimized association rule mining using genetic algorithm
... If I am a male then I am not a female. Negative association rule is an implication of the form X=>¬Y where X and Y are item sets and X∩Y=Φ. Mining association rules can be broken down into the following two sub-problems: 1. Generating all itemsets that have support greater than, or equal to, the use ...

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.
