Показать описание
In this video, I’m going to tackle a simple, common machine learning interview question: how to deal with missing values in a dataset. This problem impacts the quality of a dataset, and it can even bias the results of the machine learning model trained based on the data. This is a question that is often asked in Data Science interviews, so we’ll cover why there may be missing values in your data set, and how to deal with them.
