Those that encounter my blogs might notice two distinct types: 1) blogs that I formally prepare almost like an essay; and 2) those that are "unplugged" or informally prepared rather like a personal journal entry. The mystique of writing something where I don't exactly know the…Continue

Machine learning is increasingly used to build trading algorithms: today’s machine learning algorithms can deal with incredibly complex problems, including portfolio choice. At the same time, there is now a vast amount of data freely available – alongside…Continue

Summary: Things are getting repetitious and that can be boring. Still, looking at lessons from the 90s it’s clear there are at least one or two decades of important economic advances that will based on our current AI/ML. Then some thoughts on where that next really huge breakthrough will come from that will return our initial excitement.

You may want to check out my code on regime switching copula models.The toolbox is designed to estimate the parameters of a regime switching copula model, assuming two regimes. Each regime can be described by any of the following five copulas:
The correlation coefficient, rho, for the eliptical copulas and the copula parameter tau, for Clayton and…Continue

A fictitious retailer which I am calling Malwart sells automobiles and automotive parts. On this blog I will be focused on the sale of a particular automobile model called the Blair - a sporty compact that can be ordered in custom colour schemes. Because all sales must be done by clients that also have accounts,…Continue

The images on this blog are from an algorithmic environment that I first developed about 15 years ago - rendered using a graphical system that I wrote in Java. A “differential lattice” is a structured array of differences between two points: e.g. the difference between the closing price of a stock on day T-0 (today) and T-6 (a week ago). Consequently, if the closing prices are $10.10, $10.20, $10.30, $10.40, and $10.50 (today), then 0/3 is from T-0/T-3 or $10.50 less $10.20 = $0.30. A…Continue

Years ago, it was very time consuming to translate the text from an unknown language. Using simple vocabularies with word-for-word translation was hard for two reasons: 1) the reader had to know the grammar rules and 2) needed to keep in mind all language versions while translating the whole sentence.

About a month ago in a blog, I introduced what I described as a “spectral attenuation monitor.” At the time I only had an image from MS Works that…Continue

It’s possible I haven’t shared my story of being asked whether people can leap over lampposts. The question was posed by a university professor although I don’t recall the exact context. In response, I asked if the people are on this planet. He hissed at me, “Of course they are on this planet!” Some planets have low gravitational fields that make it possible for humans to leap great heights. At the time it didn’t seem like an oratorical question; and so I made an effort to answer it. …Continue

I have been writing about the Crosswave Differential Algorithm for a number of years. I described in previous blogs how the algorithm emerged almost by accident while I was attempting to write an application intended to support quality control. In this blog I will be discussing the event model that powers the algorithm. Events are the details and circumstances…Continue

Machine Learning is all about creating an artificial brain to perform a task by itself. In most cases that task is Prediction.
How to create a brain which can do predictions ?
A Data science-based solution needs to address problems at multiple levels. While it addresses a business problem, computationally it is comprised of a pipeline of algorithm which, in turn, operates on relevant data presented in proper format. Thus to understand the them we need to focus at least at the
Contrary to the popular belief, almost all non-trivial data science solutions are needed to be…Continue

In this blog, I will be considering theory developments from changes in methodology. But first I want to express an opinion on the significance of using numbers. A "number" represents an amplitude or magnitude: 5 pencils; 13 paperclips; 50 sheets of paper. The purpose of these numbers is to facilitate the counting of things that are presumably the same in a specific way: e.g. all 5 pencils are in fact pencils - for if 1 were an eraser, there would be 4 pencils and 1 eraser. The use of…Continue

Data visualisation is the process of displaying data in visual formats such as charts, graphs or maps. This method is commonly used to grasp more meaning out of a snapshot of data which in other approaches might require sorting through piles of spreadsheets and great quantity of reports. With the amount of data growing rapidly it is more important than ever to interpret all of this information correctly and quickly to make well-informed business decisions.
Graph visualisation has a…Continue
I have been using the term "mass data assignment" in my blogs. I thought I should offer the community some simulated examples. These are simple simulations: all the data is in one place in an agreeable format. The file contents are meant to be easy to peruse. When I was younger, there was a television series called "Stargate SG-1." I have a number of seasons on DVD. In this series, a special branch of the U.S. Air Force visits offworld sites using stable wormholes: teams enter the wormholes…Continue

“The Purple People” - The conundrum of finding business expertise among Data Scientists.
Over the last several months, as I looked at addressing the business needs across various industries as someone leading a team of Data Scientists, the question of domain expertise invariably cropped up.
Attending one meeting with a Pharmaceutical company, I was posed with the question of, "Have you done work in the areas of Rare Signal detection?" In a similar vein, while…
