Data preprocessingis a fundamental step in data analysis and machine learning. It’s an intricate process that sets the stage for the success of any data-driven endeavor. At its core, data preprocessing encompasses an array of techniques to transform raw, unrefined data into a structured and coh...
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...

Data preprocessing involves transforming raw data to well-formed data sets so that data mining analytics can be applied. Raw data is often incomplete and has inconsistent formatting. The adequacy or inadequacy of data preparation has a direct correlation with the success of any project that involve...
This data preparation chapter is of paramount importance for implementing statistical machine learning methods for genomic selection. We present the basic linear mixed model that gives rise to BLUE and BLUP and explain how to decide when to use fixed or random effects that give rise to best ...
