DATA PREPROCESSING

Importance of Data Preprocessing

  • If there is no data pre-processing your machine learning model won't work properly.

  • So its like preparing for a journey, imagine you are about to go for a long journey while you have to prepare your itinenary, your flights, your hotel bookings and packing your lauggage.

  • We have to prepare some stuff in order to make sure that we build our machine learning models without any issues.

  • And this stuff that we need to prepare for machine learning trip happens to be data pre-processing.

  • We have to do it because if we don't do it we miss out on all the fun of machine learning.

  • I will make sure to make sure it as simple as possible there is all you need to know about data-processing.

  • There is all you need to know how to do to prepare any data set for any machine learning model.
