Smart Data Science Team Catastrophe

A common fallacy exists for people building data science teams that: smart hires translate to successful data science teams. What are the number one reasons you think smart data science teams fail to offer business value? The number one reason smart data science teams fail to win and provide value at the rate that they should is money. Sure you pay them well, but they just don't get the business drivers. They can't speak the language your board members, managers, and customers need to hear. Despite their data genius, they are idiots in the business world.

Quality over quantity: building the perfect data science project

In startup lingo, a “vanity metric” is a number that companies keep track of in order to convince the world — and sometimes themselves — that they’re doing better than they actually are. Vanity metrics are everywhere, and they can really hold us back when we optimize for them, rather that optimizing for something that matters. They cause us to spin our wheels, and not understand why our hard work isn’t leading to results.

What DevOps Really Means

DevOps is a new buzzword in computing circles. It encompasses many common sense ideas about the integration between business and technology and provides the narrative to bring development, delivery and operations together. DevOps is the practice of operations and development engineers participating together through the entire service lifecycle, from the design and development process all the way to production support. It replaces the traditional silo setup where you have a team that writes the code, another team to test it, yet another team to deploy it, and even another team yet to operate it.

Machine Un-Learning: Why Forgetting Might Be the Key to AI

For humans, forgetting is more than just a failure to remember; it’s an active process that helps the brain take in new information and make decisions more effectively. It’s possible that our brains and distinctly human processes, like forgetting, hold the map to creating strong artificial intelligence, but scientists are collectively still figuring out how to read the directions. Now, data scientists are applying neuroscience principles to improve machine learning, convinced that human brains may hold the key to unlocking Turing complete artificial intelligence.

The AI War Machine: Our Darkest Day

Today we have AI metrics we applaud, like deaths-per-100-million-miles-driven. The metric sounds dark, but it is going down thanks to self-driving cars. The darkest metric will be discussed in private, away from the public eye. As AI war vendors compete on billion dollar contracts they will use kill-death-ratio (KDR) as a selling point. The Manhattan project of AI could be the physical modeling of the human body in these war simulations. The medical research efforts might accidentally enable a darker use case for the military. A big breakthrough with robots and AI is the ability to train them in a virtual environment.
