Several years ago as the VP of Advanced Projects (the company’s Skunk Works) I had the privilege to assemble and work with a very talented group of PhD level engineers in the then exploding field of ecommerce. My little team was commissioned to explore and discover new ways to monetize the online business of merchant ratings and price comparison shopping. Our success turned out to be wholly dependent on the discovery of new information functions and their implementation in the form of efficient algorithms. In the end the company and we all benefitted from this work. However, at the start there was considerable debate as to why we should devote such high-powered and expensive talent to developing things called algorithms.
Part of our explanation to non-technical management included a sign over the door to our section of offices (I made sure my guys did not work in cubicles) that announced ‘Algo Atelier’, and underneath it was posted a sheet of paper titled It’s ALL in the Algorithm which began-
“Civilization started when our ancestors put together enough algorithms to pass on to the next generation, formalizing what was learned and successfully practiced in the last. Such formalization of someone’s knowledge into a communicable algorithm allowed us to leap ahead of the glacial evolutionary learning processes that anchor the development of the lower species. And those of us who algorized better, leaped further and faster.”

Ah, that first step is a big critical one! "Data – sets of facts and beliefs that describe the real world. All observations are captured as data." The world is full of wonderful algorithms, but if they are fed garbage the final result is garbage. As I recall is was a missed placed decimal point that crashed the first Surveyor that was suppose to land on the moon, the Kalman filter working just fine, it was bad data. I was static electricity that scrambled the data fed the Kalman on the FB-111, and the computer sent me a message, "I am shutting down, we cannot get there from here." One of the Mars Explorers crashed when the filter got centimeters when it was expecting inches. No sign over my door, just a plague on the wall. GARBAGE IN, GARBAGE OUT!
