Data preprocessing, a component ofdata preparation, describes any type of processing performed on raw data to prepare it for anotherdata processingprocedure. It has traditionally been an important preliminary step fordata mining. More recently, data preprocessing techniques have been adapted for training...

relationships, and insights from the prepared data. The engine executes tasks such asclassification, clustering,regression, and association rule mining, depending on the specific goals of the analysis. The engine’s performance
Data preprocessing involves cleaning, transforming, and integrating data from different sources. This includes handling missing values, removing outliers, and normalizing data to ensure data quality and consistency. Data exploration and visualization techniques help you understand the underlying patterns and ...
Data preprocessingResearch performanceUbiquitous learning challenges students to become adept at information retrieval, management and synthesis from a variety of sources. This sparks discovery activities that are student-centred and personalized. Personalized means that the learning is best conducted in the ...
