Part of data reduction but with particular importance, E.g., many tuples have no recorded value for several, attributes, such as customer income in sales data, inconsistent with other recorded data and thus deleted, certain data may not be considered important at the, not register history or changes of the data, (assuming the tasks in classification—not effective when the, percentage of missing values per attribute varies, Use a global constant to fill in the missing value, Use the attribute mean to fill in the missing value, Use the attribute mean for all samples belonging to the same.

Tech II semester (JNTUH-R13) INFORMATION TECHNOLOGY Web mining uncover knowledge about web contents, web structure, web usage and web dynamics Data Mining is a process of discovering various models, summaries, and derived values from a given collection of data. Quality decisions must be based on quality data, Data warehouse needs consistent integration of, intrinsic, contextual, representational, and, Fill in missing values, smooth noisy data, identify or, remove outliers, and resolve inconsistencies, Integration of multiple databases, data cubes, or files, Obtains reduced representation in volume but produces. Use the most probable value to fill in the missing value: inference-based such as Bayesian formula or decision tree.
