Aayush Srivastava takes us through some pre-processing activities in machine learning:
After selecting the raw data for ML training, the most important task is data pre-processing. In broad sense, data preprocessing will convert the selected data into a form we can work with or can feed to ML algorithms. We always need to preprocess our data so that it can be as per the expectation of machine learning algorithm
Read on for examples of pre-processing steps and how pre-processing differs from data cleaning.
