More exercises focused on cleaning and preprocessing data, including dealing with outliers, duplicates, and data normalization. [AnEditoris available at the bottom of the page to write and execute the scripts.] 1. Handling Missing Data in Pandas Write a Pandas program to fill missing values (NaN...
Data preprocessing is one of the first and most important steps in data analysis. In this project, you will learn how to improve the quality of your input data by removing the features with low predictive value, engineering new ones, and dealing with multicollinearity. You’ll apply these conc...
and feature engineering. If the data scientists are satisfied with the results, they can push the preprocessing task to adata engineerwho figures out how to scale it for production. If not, the data scientists go back and change how they executed the data cleansing and feature engineering steps...
Data integration is a key aspect of data preprocessing. It involves combining data from different sources into a single, coherent dataset. This process is crucial when dealing with large volumes of data from various sources, as it ensures that all the data is consistent and can be analyzed as...
