Wrongness of the Nogs

Recently, I encountered the mystery of a stock trading algorithm that habitually makes the wrong investment decision.  It is usually wrong 55 to 60 percent of the time.  This algorithm makes use of simulated traders – usually a thousand of them.  Each trader is triggered to do buy and sell orders using a purely technical approach – that is to say, by analyzing the price.  I call the simulated traders that make money “the Nogs.”  By definition, all of the Nogs are winners. …

Machine Learning for CEOs

Lee Sedol Vs Alpha Go

Visual Analytics- Why & How- A light introduction

Think of all the self-service things you use in a day. Petrol stations, ATMs, Online/Apps for stock trading, banking, and shopping. The idea behind all this:

  • Convenience to customers
  • Reduced costs for providers
  • Freedom of choice about what I want, when I want without involvement of others in my minute-to-minute decisions.

We love to see and track health stats on Fitbit, Apple Watch, and Garmin.

An important part of my job - which I don't recall ever learning in school - is designing data-oriented processes. I can program in a number of computer programs. Writing a computer program certainly involves designing a process. Many people have the experience of being at a line-up - perhaps at an airport or cashier. At some point, somebody designed that line premised on how people would be processed. A web designer might create an online registration system for students that wish to enroll…

Embracing Conflict to Fuel Digital Innovation

When talking to clients about their business goals, most business executives are pretty clear as to what they want to accomplish, such as reducing customer churn or reducing inventory costs or improving quality of care or improving product line profitability.  But these “one dimensional” business initiatives really don’t push the organization’s innovative thinking.  For example, I can easily reduce marketing costs if I significantly reduce advertising and…
