Why Machine Learning Does Not Have to Be So Hard

Last Updated on July 13, 2019 Technical topics like mathematics, physics, and even computer science are taught using a bottom-up approach. This approach involves laying out the topics in an area of study in a logical way with a natural progression in complexity and capability. The problem is, humans are not robots executing a learning program. We require motivation, excitement, and most importantly, a connection of the topic to tangible results. Useful skills we use every day like reading, driving, […]

Comparing 13 Algorithms on 165 Datasets (hint: use Gradient Boosting)

Last Updated on August 21, 2019 Which machine learning algorithm should you use? It is a central question in applied machine learning. In a recent paper by Randal Olson and others, they attempt to answer it and give you a guide for algorithms and parameters to try on your problem first, before spot checking a broader suite of algorithms. In this post, you will discover a study and findings from evaluating many machine learning algorithms across a large number of […]

How to Think About Machine Learning

Last Updated on August 15, 2019 Machine learning is a large and interdisciplinary field of study. You can achieve impressive results with machine learning and find solutions to very challenging problems. But this is only a small corner of the broader field of machine learning often called predictive modeling or predictive analytics. In this post, you will discover how to change the way you think about machine learning in order to best serve you as a machine learning practitioner. After […]

Machine Learning Development Environment

The development environment that you use for machine learning may be just as important as the machine learning methods that you use to solve your predictive modeling problem. A few times a week, I get a question such as: What is your development environment for machine learning? In this post, you will discover the development environment that I use and recommend for applied machine learning for developers. After reading this post, you will know: The important distinctions between the role […]

Analytical vs Numerical Solutions in Machine Learning

Do you have questions like: What data is best for my problem? What algorithm is best for my data? How do I best configure my algorithm? Why can’t a machine learning expert just give you a straight answer to your question? In this post, I want to help you see why no one can ever tell you what algorithm to use or how to configure it for your specific dataset. I want to help you see that finding good data/algorithm/configuration […]

How to Get the Most From Your Machine Learning Data

Last Updated on June 30, 2020 The data that you use, and how you use it, will likely define the success of your predictive modeling problem. Data and the framing of your problem may be the point of biggest leverage on your project. Choosing the wrong data or the wrong framing for your problem may lead to a model with poor performance or, at worst, a model that cannot converge. It is not possible to analytically calculate what data to […]

The Model Performance Mismatch Problem (and what to do about it)

What To Do If Model Test Results Are Worse than Training. The procedure when evaluating machine learning models is to fit and evaluate them on training data, then verify that the model has good skill on a held-back test dataset. Often, you will get a very promising performance when evaluating the model on the training dataset and poor performance when evaluating the model on the test set. In this post, you will discover techniques and issues to consider when you […]
