A Data-Driven Approach to Choosing Machine Learning Algorithms

Last Updated on April 4, 2018 If You Knew Which Algorithm or Algorithm Configuration To Use,You Would Not Need To Use Machine Learning There is no best machine learning algorithm or algorithm parameters. I want to cure you of this type of silver bullet mindset. I see these questions a lot, even daily: Which is the best machine learning algorithm? What is the mapping between machine learning algorithms and problems? What are the best parameters for a machine learning algorithm? There […]

How to Build an Intuition for Machine Learning Algorithms

Last Updated on December 13, 2019 Machine learning algorithms are complex. To get good at applying a given algorithm you need to study it from multiple perspectives: algorithmic, mathematical and empirical. It’s this last point I want to stress. You need to build up an intuition or how an algorithm behaves on real data. You need to work on lots of problems. In this post I want to encourage you to use small in-memory datasets when starting out and when […]

Inteview: Discover the Methodology and Mindset of a Kaggle Master

Last Updated on July 5, 2019 What does it take to do well in competitive machine learning? To really dig into this question, you need to dig into the people that do well. In 2010 I participated in a Kaggle competition to predict the outcome of chess games in the future. It was a fascinating problem because it required you to model the rating of the players from historical games and propagating those ratings into the future to make predictions. […]

An Introduction to Feature Selection

Last Updated on August 15, 2020 Which features should you use to create a predictive model? This is a difficult question that may require deep knowledge of the problem domain. It is possible to automatically select those features in your data that are most useful or most relevant for the problem you are working on. This is a process called feature selection. In this post you will discover feature selection, the types of methods that you can use and a […]

5 Machine Learning Areas You Should Be Cultivating

Last Updated on June 7, 2016 You want to learn machine learning to have more opportunities at work or to get a job. You may already be working as a data scientist or machine learning engineer and looking to improve your skills. It is about as easy to pigeonhole machine learning skills as it is programming skills (you can’t). There is a wide array of tasks that require some skill in data mining and machine learning in business from data […]

Model Selection Tips From Competitive Machine Learning

Last Updated on June 7, 2016 After spot checking algorithms on your problem and tuning the better few, you ultimately need to select one or two best models with which to proceed. This problem is called model selection and can be vexing because you need to make a choice given incomplete information. This is where the test harness you create and test options you choose are critical. In this post you will discover the tips for model selection inspired from […]
