Summary: True prescriptive analytics requires the use of real optimization techniques that very few applications actually use. Here’s a refresher on optimization with examples of where and how they’re best used.
In this blog, I will be discussing some distinct types of data involved in feedback. The types that I will be covering are as follows: 1) structural; 2) event; 3) quantitative; 4) contextual; and 5) systemic. In 2014, I recall reading a number of blogs about three types of data: prescriptive, descriptive, and predictive. There was a data scientist apparently on tour lecturing extensively about these three types. I don't recall the individual's name. Well, prescription, description, and…Continue

I learned that after renovations to a house, the furnace might cycle on and off more frequently; this can leave some parts of the house too cold. A wood-burning stove or fireplace should be treated as a part of a system. Open doors and windows in the dwelling can cause exhaust from such appliances to enter living spaces. I realize that these particular examples of systems…Continue

Smart organizations are using the power of data science and data produced by embedded sensors and machine devices to better measure performance, discover patterns, prevent problems, and improve…Continue
In this blog post, I describe my early experiences leading me to conclude, data as we know it tends to be "disembodied" - that is to say, often lacking any kind of connection to different types of bodies. When we talk about things being disembodied, I suspect some form of decapitation is…Continue

I have so far encountered two general types of data . . .
This is data that conforms to prescribed criteria. I sometimes describe it has the metrics of criteria or measurements of conformity. For instance, an organization might want to measure something potentially obscure like "efficiency." It therefore becomes necessary to establish under what conditions or criteria something is efficient. I describe…Continue
