ELEMENTARY IMAGE ANALYSIS: GRAYSCALE FROM COLOUR IMAGES

A colour two-dimensional image is a triple of matrices of pixel size where each value is between 0 and 255.  I am looking into the problem of Optical Character Recognition.  Since most of my numerical algorithms will not worry too much about colours for the moment, I needed to know the ways of transforming the … More ELEMENTARY IMAGE ANALYSIS: GRAYSCALE FROM COLOUR IMAGES

HOW ZULFIKAR MOINUDDIN AHMED THINKS ABOUT POTENTIAL CUSTOMERS OF A PRODUCT

I have a couple of failures in my entrepreneurial efforts in the past decade and no big entrepreneurial successes yet.  Partly this is because I was not thinking clearly enough about entrepreneurial success.  Now I want to move slowly toward technology entrepreneurship again and I want to think about things afresh.  When I ask myself … More HOW ZULFIKAR MOINUDDIN AHMED THINKS ABOUT POTENTIAL CUSTOMERS OF A PRODUCT

STATISTICAL DATA ANALYSIS USING R AS THE BACK END: OLD IDEA FROM A COUPLE OF DECADES AGO

I think most people would agree that Excel is the de-facto data front end with more than 750 million users.  I code exclusively on R+python these days on a Linux but I have ideas for a general purpose statistical software package on Excel.  I found this quite helpful.  Alteryx produces a simplified drag-and-drop on top … More STATISTICAL DATA ANALYSIS USING R AS THE BACK END: OLD IDEA FROM A COUPLE OF DECADES AGO

SIMPLIFIED STORY OF HOW GAUSSIAN DISTRIBUTION BECAME KING BETWEEN 1810 AND 1900

The normal distribution was actually introduced by Laplace early in 1810 and came out with the Central Limit Theorem that the aggregate of a large number of errors will be approximately normally distributed; later in 1810 Laplace read Gauss writing on least-square estimation.  It was Laplace who made the revolutionary connection between the Gaussian probability … More SIMPLIFIED STORY OF HOW GAUSSIAN DISTRIBUTION BECAME KING BETWEEN 1810 AND 1900

FORMAL TEST FOR MACROECONOMIC VARIABLES BEING DESCRIBED BETTER BY GENERALIZED HYPERBOLIC DISTRIBUTION THAN NORMAL DISTRIBUTION

The history of probability density functions starts with the introduction of error curves by THOMAS SIMPSON in 1755.  I always find things easier to understand by looking at the intellectual history; otherwise the intellectual world seems too anarchic to me.  Intellectual history of issues not only grounds me but very often I find that the … More FORMAL TEST FOR MACROECONOMIC VARIABLES BEING DESCRIBED BETTER BY GENERALIZED HYPERBOLIC DISTRIBUTION THAN NORMAL DISTRIBUTION
