Data Mining | Data Preprocessing: In this tutorial, we are going to learn about the data preprocessing, need of data preprocessing, data cleaning process, data integration process, data reduction process, and data transformations process.ByHarshita JainLast updated : April 17, 2023 ...
However, it is known that original data is always dirty and not suitable for further analysis which have become a major obstacle of finding knowledge.This thesis aims to introduce this new field and data preprocessing as a critical step in a data mining project as well as its practical part ...
This is a simple yet effective method for filling gaps in numerical features. Advanced Methods: Approximate missing values based on neighboring data points. Linear interpolation or other statistical techniques can help when data follows a predictable trend.Similar Read: Data Preprocessing In Data Mining...
