In this article, I'll use the example of scaling numerical data (numerical data: data consisting of numbers, as opposed to categories/strings; scaling: using basic arithmetic to change the range of the data; more details to follow) to demonstrate the importance of considering preprocessing as p...
You must have heard this phrase if you have ever encountered a senior Kaggle data scientist or machine learning engineer. The fact is that this is a true phrase. In a real-world data science project, data preprocessing is one of the most important things, and it is one of the common fac...
