THIS TUTORIAL HAS REQUIREMENTS AND INSTRUCTIONS LISTED BELOW
This tutorial provides a hands-on programming intro to advanced math for business people — showing “just enough math” to take advantage of some popular open source frameworks.
The premise is that many people take university-level math, up until the “killing fields” of calculus. Most did not continue beyond that, but still have an interest. Meanwhile, math programs in many universities cling tenaciously to Cold War-era priorities, intent on weeding out people who would not pass requirements as engineers to build missiles, etc.
With the commercial successes of Machine Learning, Cloud Computing, etc., there are very good business cases for having “just enough math” to leverage new kinds of open source tools. These days people in business need to understand more about complex graphs, sparse matrices, Bayesian priors, optimization solvers, etc., which are not hard to learn but placed far beyond calculus.
As a case in point: in preparation for their recent IPO, Twitter overhauled their revenue apps to emphasize applying semigroups, monoids, rings, algebraic graph theory, etc., to leverage functional programming for efficient parallel processing at scale. Those topics may sound obscure, but 100 lines of Python illustrate the math clearly.
The formula applied in the tutorial is simple: a series of sections build on each other, where each introduces a few clear math concepts, discusses the history and typical uses, along with a sample business use case illustrating how to leverage that math, followed by brief code examples in Python that show how to solve for the use case. Then we look at open source projects which get used in production for similar kinds of work.
Part 1: Show Me The Monoid
Abstract algebra is a basis for parallel processing and functional programming, which ultimately leads to very good software engineering. Monoids, semigroups, rings, etc., are how we build Enterprise data workflows based on OSS frameworks such as Summingbird (Scala) and MBrace (F#).
Part 2: Lies, Damn Lies, Statistics, and Bayesian Statistics
A look at Bayesian statistics, point estimates, and other ways of making decisions when the business criteria are in flux and changing over time. Not the statistics that you learned in college, but what gets used in commerce, especially in the context of “Internet of Things” and sensor arrays.
Part 3: The Red Pill
Building on the above to explore some of the more useful parts of linear algebra, its relation to algebraic graph theory, graph queries, eigenvalues, factorization, etc. These provide the heavy lifting currently in high-ROI apps at scale.
Part 4: Caterpillar Won’t Be Building A Social Network
Leveraging linear algebra to introduce optimization theory, convex spaces, operations research… Focus on a pricing model example of linear programming using PyGLPK and then Genetic Programming for business use cases in which calculus does not apply.
Part 5: A Winning Approach
A simple conceptual framework to represent real-world problems as graphs, then solve the graphs as sparse matrices, implemented in clusters based on cloud computing.
In summary, the first four parts introduce different advanced math topics that are practical (and arguably essential) to use in business. Then the fifth part ties these pieces together into a conceptual whole, as a new way to approach computational thinking.
