Data pre-processing for Machine Learning in Python

Data Preprocessing refers to the steps applied to make data more suitable for data mining. In this course, we are going to focus on pre-processing techniques for machine learning. Pre-processing is the set of manipulations that transform a raw dataset to make it used by a machine learning model. It is necessary for making our data suitable for some machine learning models, to reduce the dimensionality, to better identify the relevant data, and to increase model performance. It's the most important part of a machine learning pipeline and it's strongly able to affect the success of a project.
