Determining Sample Size in One Picture

Determining sample sizes is a challenging undertaking. For simplicity, I've limited this picture to the one of the most common testing situation: testing for differences in means. Some assumptions have been made (for example, normality and equal sample sizes). Additionally, the…

New word for Data Science - Signuology

I propose a new word for data science for sparking new thinking. Signuology is defined as the study of sets of characteristic predictive signals contained within data in the form of combined features of the data that are characteristic of an observation of interest within the data.

The terms data mining and data structure imply rigid and discrete characteristics. A signal has more flexibility, borrowing from ideas contained in the superposition principle in physics. One can take the…

In Digital Transformation, Economies of Learning More Powerful than Economies of Scale

Key topics of this blog:

  • Economies of scalehave historically given large enterprises unsurmountable market advantages through the exploitation of mass production, distribution and marketing.
  • In Digital Transformation, “Economies of Learning”are more powerful than “Economies of Scale” because of the ability to learn and deploy those learnings within digital assets faster.
  • Classic ERP “Big…

Demystifying the Math of Support Vector Machines (SVM)

This article was written by Krishna Kumar Mahto.

 So, three days into SVM, I was 40% frustrated, 30% restless, 20% irritated and 100% inefficient in terms of getting my work done. I was stuck with the Maths part of Support Vector Machine. I went through a number of YouTube videos, a number of documents, PPTs and PDFs of lecture notes, but…

How to Automatically Determine the Number of Clusters in your Data - and more

Determining the number of clusters when performing unsupervised clustering is a tricky problem. Many data sets don't exhibit well separated clusters, and two human beings asked to visually tell the number of clusters by looking at a chart, are likely to provide two different answers. Sometimes clusters overlap with each other, and large clusters contain sub-clusters, making a decision not easy.

For instance, how many clusters do you see in the picture below? What is the optimum number…

System Engineering Methodology for Design Improvement (Work in progress…)

A system is an entity that behaves based on the intrinsic characteristics of its components and the external forces that drive these elements to react as a result of their interaction with the environment.

When optimizing a system, three scenarios should be defined. The first is identifying all of its components, boundaries and the conditions acting upon it. The system intrinsically has a homeostatic point where it wants to exist and that may be not optimal for the…
