This is a project I've been working on for some time to help improve the missed opportunity rate (no-show rate) at all medical centers. It demonstrates how to extract datasets from an SQL server and load them directly into an R environment. It also demonstrates the entire machine learning process, from engineering new features, tuning and training the model, and finally measuring the model's performance. I would like to share my results and methodology as a guide to help…Continue

The spectrum of data scientist roles is so broad that I will keep this discussion for my next post. What I really want to focus is on what are the distinctive characteristics of a great data scientist.
Over the years that I have worked with data and analytics I have found that this has almost nothing to do with…Continue

Can data bring the best in humanity? Can it evoke emotions? Can it speak to us?
Every time I walk by a memorial wall, I am filled with visuals. Some folks run their fingers on the wall and when they spot a dear one’s name, a feeling of acknowledgement envelops their face. Many others stand in front of the wall to capture their own memories with their camera.
As I watch the wall, I stand in awe. The combination of symbolism of the wall in totality and a tribute…Continue

I came across the story of a manager who felt that the best way to encourage desirable behaviours was through reward and humiliation. This encouragement occurred indirectly through what I would describe as “persuasive data”: a table of data went out each week showing the best and worst performing employees. Everyone in the team could see the stats plainly along with the names of coworkers. They were encouraged to make comparisons. This represents an aggressive use of data. From my…Continue
