The ODSC March Madness Redemption Bracket

The ODSC March Madness Redemption Bracket

What’s the Difference Between Artificial Intelligence, Machine ...

This is the first of a multi-part series explaining the fundamentals of deep learning by long-time tech journalist Michael Copeland. Artificial intelligence is the future. Artificial intelligence is science fiction. Artificial intelligence is already part of our everyday lives. All those statements are true, it just depends on what flavor of AI you are referring […]

ACID: How to screw it up!

ACID: How to screw it up!

In my previous post, I described four applications (three implemented, one an example) that require, or at least strongly benefit from, strong ACID transactions. With that out of the way, we can now get to the fun bits. Today’s claim: most databases that claim to be 100% ACID compliant fudge definitions, goof up, or deliberately […]

Does TensorFlow Suffer from the Second-System Effect?

Does TensorFlow Suffer from the Second-System Effect?

In The Mythical Man Month, Fred Brooks includes an essay called The Second-System Effect. The second-system effect describes two problems likely when building a new project like one you’ve done before: too many features: “frill after frill and embellishment after embellishment” focus on the wrong features: “a tendency to refine [obsolete] techniques” The “too many […]

How the ODSC March Madness Bracket Fared Over the First Weekend

How the ODSC March Madness Bracket Fared Over the First Weekend

Last week we published an article about our March Madness bracket. In it we described the data science methods we used to predict the outcomes of all 63 games. Here’s how our bracket did after the first two rounds and 48 games. Our bracket did pretty poorly. After a hugely promising start, in which we correctly predicted 15 out of […]
