Assessment Metrics for Clustering Algorithms
Assessing the quality of your model is one of the most important considerations when deploying any machine learning algorithm. For supervised learning problems, this is easy. There are already labels for every example, so the practitioner can test the model’s performance on a reserved evaluation set. We don’t have... Read more
Three Challenges for Open Data Science
There are three types of lies: lies, damned lies, and ‘big data.’ That’s the message Amazon machine learning director Neil Lawrence began his ODSC Europe 2016 lecture with before laying out the three largest challenges for open data science and our data-centered society. As Lawrence sees it, those challenges... Read more
Comparing Features of 4 Popular Machine Learning Platforms
Machine learning, the term and the technology, has been of paramount importance and relevance in the context of computational applications for years. Arthur Samuel first came up with the word “machine learning” in 1957. Machine learning is basically a part of artificial intelligence that evolves through the fields of... Read more
The Potential of Communities and Machine Learning for Good
For any technology to be successful, it needs to move from the early adopter market segment to the majority, i.e., crossing the chasm. Up until now, machine learning has been primarily in the hype phase and adoption has been mostly driven by the early adopters and innovators. I envision that... Read more
Machine Learning for Beginners – a How-to Guide
Addressing the audience at Open Data Science Conference 2017 in Boston, Kirill Eremenko and Hadelin de Ponteves stepped listeners through a collection of different machine learning techniques spanning a wide breadth, explaining the basics behind each to get users off the ground. This is a great tutorial for getting... Read more
Pervasive Simulator Misuse with Reinforcement Learning
The surge of interest in reinforcement learning is great fun, but I often see confused choices in applying RL algorithms to solve problems. There are two purposes for which you might use a world simulator in reinforcement learning: Reinforcement Learning Research: You might be interested in creating reinforcement learning algorithms for...

A probability on its own is often an uninteresting thing. But when we can compare probabilities, that is when their full splendour is revealed. By comparing probabilities we are able form judgements; by comparing probabilities we can exploit the elements of our world that are probable; by comparing probabilities... Read more
The Barbell Effect of Machine Learning
If there is one technology that promises to change the world more than any other over the next several decades, it is arguably machine learning. By enabling computers to learn certain things more efficiently than humans and discover certain things that humans cannot, machine learning promises to bring increasing... Read more
Why Machine Learning Is A Metaphor For Life
Seriously. Hear me out on this. The more I learn about ML, the more I see the number of similarities there are between life and machine learning concepts. Specifically, let’s think about neural networks. Let’s think of a neural net that has a bunch of input nodes and one output... Read more
In this post we’ll provide a general introduction to machine learning, which tries to highlight the underlying technical challenges and where we have solutions. Machine learning is the principle technology underpinning the recent advances in artificial intelligence. But what is machine learning? And why is it important? Machine learning... Read more
