Having one or two algorithms that perform reasonably well on a problem is a good start, but sometimes you may be incentivised to get the best result you can given the time and resources you have available. In this post, you will review methods you can use to squeeze out extra performance and improve the […]

How to Evaluate Machine Learning Algorithms
Once you have defined your problem and prepared your data you need to apply machine learning algorithms to the data in order to solve your problem. You can spend a lot of time choosing, running and tuning algorithms. You want to make sure you are using your time effectively to get closer to your goal. […]
How to Prepare Data For Machine Learning
Machine learning algorithms learn from data. It is critical that you feed them the right data for the problem you want to solve. Even if you have good data, you need to make sure that it is in a useful scale, format and even that meaningful features are included. In this post you will learn […]
How to Define Your Machine Learning Problem
The first step in any project is defining your problem. You can use the most powerful and shiniest algorithms available, but the results will be meaningless if you are solving the wrong problem. In this post you will learn the process for thinking deeply about your problem before you get started. This is unarguably the […]
Data, Learning and Modeling
There are key concepts in machine learning that lay the foundation for understanding the field. In this post, you will learn the nomenclature (standard terms) that is used when describing data and datasets. You will also learn the concepts and terms used to describe learning and modeling from data that will provide a valuable intuition […]
Where Does Machine Learning Fit In?
Machine Learning is a multidisciplinary field and it can be very confusing when you are getting started to differentiate machine learning from the closely related fields of Artificial Intelligence and Data Mining. In this post you will learn about those fields that are related to machine learning. Specifically, you will learn about the boundaries of […]
Programmers Should Get Into Machine Learning
Programmers should get involved in the field of machine learning because they are uniquely skilled to make huge contributions. In this post you will learn that as a programmer it can be easy to overlook the skills you have and overvalue those things you don’t know. You will learn about four opportunities for programmers to […]
