I find that the best way to learn and understand a new machine learning method is to sit down and implement the algorithm. In this tutorial we’ll work on decision trees in Python (ID3/C4.5 variant).
In most machine learning courses a lot of emphasis is given to binary classification tasks. However, I found that the most useful machine learning tasks try to predict multiple classes and more often than not those classes are grossly unbalanced.
In this post we’ll see how to clean data, and how to deal with geographical information in Python. This post is part of a data science project of the room rental prices in Vancouver.
In this post we’ll describe how I downloaded 1000 room listings per day from a popular website, and extracted the information I needed (like price, description and title).
Have you ever wondered what is a good price for a room in Vancouver?
In this post we will learn how to use the ast module to extract docstrings from Python files.
