Quality 4.0 and Digital Transformation
The fourth industrial revolution is characterized by intelligence: smart, hyperconnected agents deployed in environments where humans and machines cooperate to achieved shared goals — and using data to generate value. Quality 4.0 is the name we give to the pursuit of performance excellence in the midst of this theme of technological progress, which is sometimes…

What is Quality 4.0?
COMING FEB 2020 My first post of 2018 addresses an idea that’s just starting to gain traction – one you’ll hear a lot more about from me soon: Quality 4.0. It’s not a fad or trend, but a reminder that the business environment is changing, and that performance excellence in the future will depend on…

A Simple Intro to Q-Learning in R: Floor Plan Navigation
This example is drawn from “A Painless Q-Learning Tutorial” at http://mnemstudio.org/path-finding-q-learning-tutorial.htm which explains how to manually calculate iterations using the updating equation for Q-Learning, based on the Bellman Equation (image from https://www.is.uni-freiburg.de/ressourcen/business-analytics/13_reinforcementlearning.pdf): The example explores path-finding through a house: The question to be answered here is: What’s the best way to get from Room 2 to…

Reinforcement Learning: Q-Learning with the Hopping Robot
Overview: Reinforcement learning uses “reward” signals to determine how to navigate through a system in the most valuable way. (I’m particularly interested in the variant of reinforcement learning called “Q-Learning” because the goal is to create a “Quality Matrix” that can help you make the best sequence of decisions!) I found a toy robot navigation…

A Newbie’s Install of Keras & Tensorflow on Windows 10 with R
This weekend, I decided it was time: I was going to update my Python environment and get Keras and Tensorflow installed so I could start doing tutorials (particularly for deep learning) using R. Although I used to be a systems administrator (about 20 years ago), I don’t do much installing or configuring so I guess…

Where Do Z-Score Tables Come From? (+ how to make them in R)
Every student learns how to look up areas under the normal curve using Z-Score tables in their first statistics class. But what is less commonly covered, especially in courses where calculus is not a prerequisite, is where those Z-Score tables come from: figuring out the area under the normal curve for all possible places you…
