Data Preprocessing in Python - Towards Data Science

The transform function will transform all the data to a same standardized scale. X_train = sc_X.fit_transform(X_train) X_test = sc_X.transform(X_test) So here you go, you have learned the basics steps involved in data preprocessing. Now you can try applying these preprocessing techniques on some real-world data sets.

Data pre-processing - Wikipedia

Data preprocessing is an important step in the data mining process. The phrase "garbage in, garbage out" is particularly applicable to data mining and machine learning projects. Data-gathering methods are often loosely controlled, resulting in out-of-range values (e.g., Income: −100), impossible data combinations (e.g., Sex: Male, Pregnant: Yes), missing values, etc. Analyzing data that has ...
