Mass Data Simulations

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…

Inferential Modeling and Application of Analogs

When discussing the use of algorithms, the issue of durability or portability has to be considered. For example, a stock trading algorithm might be used in a missile guidance system. The algorithm would have to operate on an abstract kinetic level rather than for a specific application. I have written in the past about using the same algorithm to study stocks, earthquakes, hurricanes, electro-cardiograms, and attempts at evasion - using my mouse in a game environment. Wouldn't an abstraction…

The Perfect Cheer

I recall the first time I encountered the idea of "asset allocation" many years ago. As the argument goes, the perfect allocation of assets should lead to the greatest return possible in light of one's risk tolerance. Perhaps thousands of years ago, although I haven't studied this in any detail, somebody had the idea that dancing in just the right way might satisfy the spirits enough to cause it to rain. There is the similar notion of delivering the perfect incantation to invoke supernatural…

Overcoming Aspects of Social Disablement in Data

When the performance of an employee is evaluated, ideally there are no externalities to complicate the analysis. If the employee has a computer that is constantly freezing up - or the servers in the company frequently operate slowly - the employee's performance data will reflect the functionality and effectiveness of these systems. If the company occupies a highly competitive market, declining sales data is attributable at least in part to competition rather than the behaviours of employees.…

Why We Should Be Openly Sharing Our Personal Data With The World...

There has been an ongoing discussion recently on why everyone is sharing their data openly with the world. I found myself wondering more often why it is that through the facility of social platforms like Facebook, Twitter, Instagram, etc., we are openly publishing the infinite details of our lives. We seem to have this inherent need of self-expression through social media. I admit that I too am a culprit of constantly posting statuses, sharing my location, and uploading photos of personal…

Social Construction of Technical Trading Data

I heard an accountant once say that people in his profession are generally bad investors. I am uncertain if this is true. I never really bothered to confirm his assertion. He said that his reasons for believing so relate to the nature in which accountants interpret data, which he implied was rather literal. I personally almost always ignore "book value" - that is to say, the cost of acquisition. For me, the book value is similar to a figure of speech: the investment value never has to be…

Development as Art - Hopscotch and Robots

When I read a blog, I often find myself in deep thought as I approach the end, trying to determine if the author has said anything that I might be able to use. A blog doesn't have to say anything. Nor does it have to be useful to me specifically. It might simply offer a personal reflection on life. As a person who also writes blogs, I…

Variable Metrics Formats for Mass Data Assignments



I created this blog to further discuss the issue of mass data assignments, a methodology that allows qualitative data events to be incorporated into metrics such as performance indicators. These assignments are routine for me now after having developed a prototype. However, I am unaware of the prevalence of this or similar techniques in the broader community. So I periodically work the topic into my blogs to help stimulate discussion. When quantitative data exists, it means that we had…

Qualitative Engine for Organizational Simulations

Given the nature of the community, presumably many visitors already have a strong understanding of the nature of quantitative data. Perhaps more mysterious is the idea of qualitative data especially since it can sometimes be expressed in quantitative terms. For instance, "stress" as an internal response to an externality differs from person to person; yet it would be possible to canvas a large number of people and express stress levels as an aggregate based on a perceptual gradient: minimal,…

Dark Art of Warping



The celebrity of Toronto's mayor has certainly drawn a lot of attention to the city in recent years. Several candidates are now running for Rob Ford's job. Since the mayor is currently undergoing treatment for cancer, he decided to withhold his candidacy in the upcoming municipal election. Being a longtime resident of Toronto, and being aware of the city's wealth and poverty, I'm always interested in how these competing needs play out when it is time to vote.  Consider the interesting…

Participation in Data and the Effectiveness of Intervention

The role of statistics in data science is often debated. Despite rapid developments in technology giving access to algorithmically sophisticated approaches, I feel that statistics can still provide many worthwhile insights. If I have a database of sales figures spanning many years, I feel that I can become more aware of historic trends and seasonal patterns through the use of statistics. Statistics offers a sense of state, direction, pace, and progress. Statistics can also enable estimation…

Causality, Closet Nazis, and the Metrics of Criteria

A few semesters into my undergraduate studies, I decided to move away from campus in order to escape the incessant party atmosphere. I chose to rent an old but roomy apartment in Kitchener, Ontario. I read somewhere that this city was formerly called New Munich. One day in the dead of morning, I heard loud banging and smashing downstairs. It seemed that neither I nor my cat could sleep, so I went to investigate. I saw the owner of the building at the front entrance of the apartment holding a…

Geography of Data - Restoring the Transpositional

Above is a distribution of price differentials for the Dow Jones Industrial Average from the 1930s. The image was generated by one of my programs called Storm. I posted a few images from the same application in other blogs. If I recall correctly, the more volatile differentials (closer to the action) are at top; the more stable differentials (further from the…

Hazards of Institutional Data

A prominent discrimination case in Canada involves a firefighter named Tawney Meiorin.  Meiorin had successfully performed her duties as a firefighter for many years.  She lost her job after the introduction of mandatory testing to determine her fitness for the position.  The testing measured aerobic capacity, and it was developed in a manner that many would regard as scientific; that is to say, it used a highly quantitative and analytic approach.  However,…

Critical Data and the Organizational Construct

The term "critical thinking" is often found in job postings.  Some would argue that this essentially means, "Thinking outside the box."  Karl Marx, who asserted that labourers represent a class of people, has been described as a critical thinker.  Regardless of how a person feels about Marx, it goes without saying that the phenomena of social classes is well-established.  Politicians for instance fight for the support of the "middle class."  How precisely does such an observation by this…

Search for Embodiment in Data Mining

Above - During a Session at the Archives of Ontario in 2011

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…

Reductive Versus Expansive Data

I have so far encountered two general types of data . . .

Reductive 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…

What will America pay for H1-B Jobs?

NOTE: H1b is a Visa program where people from outside countries are allowed to work with USA companies. The visa is valid for a 3 year period and is extensible for another 3 years. 

United States Department of Labor publishes quarterly data of H1-B and other visa applications. Below is an analysis and visualization of the same data.
