Three basic operations including crossover, mutation, and selection are performed on chromosomes for the next generations. Data mining is defined as a "type of database analysis that attempts to Data mining, also referred to as text mining, is the process of using software to search large volumes of data or text to extract out specific, relevant data for use. During the procedure to hide the sensitive information, side effects of missing cost and artificial cost are thus generated and should be concerned in PPDM. Such data may implicitly contain confidential information that will lead to privacy threats if it is misused. Written Report of Part II. It is a process of extracting previously unknown and processable information from large databases and using it to make important business decisions. For instance, you may decide to remove apparently irrelevant attributes, replace missing values if any, discretize attributes in a different way, etc. Will the node be pruned or not by the technique. Privacy-preserving data mining PPDM [ 19 — 22 ] was proposed to reduce privacy threats by hiding sensitive information while allowing required information to be discovered from databases.

The process of extracting patterns from data is called data mining. ReplaceMissingValuesFilter in Weka. Supply input data to Weka and use n-fold crossvalidation to test your results. This joint analysis of the results should include: Description of the similarities and differences of the experiments run by each of you, and hence of the results obtained.

Review of Related Works Related works of genetic algorithms, data sanitization, and prelarge concept are briefly reviewed in this section. The amount of chromosomes is thus required to process the several operations in evaluation process of simple GAs. In particular, explore different ways of discretizing continuous attributes.
