Deep Diving the Data Lake – Automatically Determining What’s In There

Summary:  As your data lake grows larger and your user group more diverse you will need these tools that automatically catalog data and control access to your information.  They are a huge benefit and only enhance the spirit of free exploration of data for new value.

 

Data Lakes…

AI’s Ethical Dilemma – An Unexpectedly Urgent Problem

Summary:  In just the last 10 months based only on facial characteristics deep learning has been used to predict who is a criminal and who is gay.  These are rigorous, peer reviewed studies published in academic journals.  How should this knowledge be used and how will the public react?

Regulating AI – The Road Ahead

Summary:  With only slight tongue in cheek about the road ahead we report on the just passed House of Representative’s new “Federal Automated Vehicle Policy” as well as similar policy just emerging in Germany.  As a model of regulation on emerging AI technology we think they got this just about right.

Under the Hood with Reinforcement Learning – Understanding Basic RL Models

Summary:  Reinforcement Learning (RL) is likely to be the next big push in artificial intelligence.  It’s the core technique for robotics, smart IoT, game play, and many other emerging areas.  But the concept of modeling in RL is very different from our statistical techniques and deep learning.  In this two part series we’ll take a look at the basics of RL models, how they’re built and used.  In the next part, we’ll address some of the complexities that make development a…

More on Fully Automated Machine Learning

Summary:  Recently we’ve been profiling Automated Machine Learning (AML) platforms, both of the professional variety, and particularly those proprietary one-click-to-model variety that are being pitched to untrained analysts and line-of-business managers.  Since our first article, readers have suggested some additional companies we should look at which are profiled here along with some interesting observations about who is buying and why.

Automated Machine Learning for Professionals

Summary:  There are a variety of new Automated Machine Learning (AML) platforms emerging that led us recently to ask if we’d be automated and unemployed any time soon.  In this article we’ll cover the “Professional AML tools”.  They require that you be fluent in R or Python which means that Citizen Data Scientists won’t be using them.  They also significantly enhance productivity and reduce the redundant and tedious work that’s part of model…

Data Scientists Automated and Unemployed by 2025 - Update!

Summary:  A year ago we wrote about the emergence of fully automated predictive analytic platforms including some with true One-Click Data-In Model-Out capability.  We revisited the five contenders from last year with one new addition and found the automation movement continues to move forward.  We also observed some players from last year have now gone in different directions.  …

AI Is the Future of the Internet – and Finally Somebody Notices

Summary: You’d think that the internet was the core of the digital economy but it’s not.  Data science is the core without which the digital economy wouldn’t exist and increasingly it’s AI that’s moving the needle in consumer engagement.

 

I look forward to this time of year…

Understanding the Changing Position Roles in Data Science

Summary:  Is everyone a ‘data scientist’?  What about ‘data engineers’ and the junior versus senior, or skill level distinctions?  We do seem to need some agreement about titling.  Data Scientists is still the prestige title but there are some folks lobbying to take that title away.

Using RuleFit Ensemble Models Is About to Become Very Important

Summary:  The drive toward transparency and explainability in our modeling seems unstoppable.  Up to now that meant sacrificing accuracy for interpretability.  However, the ensemble method known as RuleFit may be the answer with both explainability and accuracy meeting or exceeding Random Forest.

 

If you’re like me and not doing modeling in a highly regulated industry like mortgage finance or insurance then when you produce a model, you are…

The Three Way Race to the Future of AI. Quantum vs. Neuromorphic vs. High Performance Computing

Summary:  There’s a three way technology race to bring faster, easier, cheaper, and smarter AI.  High Performance Computing is available today but so are new commercial versions of actual Quantum computers and Neuromorphic Spiking Neural Nets.  These two new entrants are going to revolutionize AI and deep learning starting now.

Even a Poor Model Can Have a Lot of Value

Summary:  This is a lesson in how it may be possible to snatch victory from the jaws of defeat.  1.) A good ROC score does not necessarily mean a good model. 2.) Even a weak model may be good at the top and bottom – consider how you can use that.

 

This is a lesson in how it may be possible to snatch victory from the jaws of defeat.  In our world, defeat is ending up with a poor model that doesn’t do what you’d hoped.  This story about a particular project…

Why R is Bad for You

Summary:  Someone had to say it.  In my opinion R is not the best way to learn data science and not the best way to practice it either.  More and more large employers agree.

 

Someone had to say it.  I know this will be controversial and I welcome your comments but in my opinion…
