One of the most crucial preprocessing steps in any machine learning project is feature encoding. It is the process of turning categorical data in a dataset into numerical data. It is essential that we perform feature encoding because most machine learning models can only interpret numerical data and not data in text form.
In this article, we will learn:
As usual, I will demonstrate these concepts through a practical case study using the students’ performance in exams dataset on Kaggle.
