    The Open-Source Data Science Masters

    The open-source curriculum for learning Data Science. Foundational in both theory and technologies, the OSDSM breaks down the core competencies necessary to making use of data.


    The Internet is Your Oyster

    With Coursera, ebooks, Stack Overflow, and GitHub -- all free and open -- how can you afford not to take advantage of an open source education?

    The Motivation

    We need more Data Scientists. 2018 the United States will experience a shortage of 190,000 skilled data scientists, and 1.5 million managers and analysts capable of reaping actionable insights from the big data deluge.

    -- McKinsey Report Highlights the Impending Data Scientist Shortage 23 July 2013

    There are little to no Data Scientists with 5 years experience, because the job simply did not exist.

    -- David Hardtke "How To Hire A Data Scientist" 13 Nov 2012

    An Academic Shortfall

    Classic academic conduits aren't providing Data Scientists -- this talent gap will be closed differently.

    Academic credentials are important but not necessary for high-quality data science. The core aptitudes – curiosity, intellectual agility, statistical fluency, research stamina, scientific rigor, skeptical nature – that distinguish the best data scientists are widely distributed throughout the population.

    We’re likely to see more uncredentialed, inexperienced individuals try their hands at data science, bootstrapping their skills on the open-source ecosystem and using the diversity of modeling tools available. Just as data-science platforms and tools are proliferating through the magic of open source, big data’s data-scientist pool will as well.

    And there’s yet another trend that will alleviate any talent gap: the democratization of data science. While I agree wholeheartedly with Raden’s statement that “the crème-de-la-crème of data scientists will fill roles in academia, technology vendors, Wall Street, research and government,” I think he’s understating the extent to which autodidacts – the self-taught, uncredentialed, data-passionate people – will come to play a significant role in many organizations’ data science initiatives.

    -- James Kobielus, Closing the Talent Gap 17 Jan 2013

    • Example Code in: R, Python, Sage, C, Gnu Scientific Library

    A Note About Direction

    This is an introduction geared toward those with at least a minimum understanding of programming, and (perhaps obviously) an interest in the components of Data Science (like statistics and distributed computing). Out of personal preference and need for focus, I geared the original curriculum toward Python tools and resources. R resources can be found here.

    Ethics in Machine Intelligence

    Human impact is a first-class concern when building machine intelligence technology. When we build products, we deduce patterns and then reinforce them in the world. Ethics in any Engineering concerns understanding the sociotechnological impact of the products and services we are bringing to bear in the human world -- and whether they are reinforcing a future we all want to live in.


    Linear Algebra & Programming

    Convex Optimization


    Differential Equations & Calculus

    Problem Solving


    Get your environment up and running with the Data Science Toolbox


    Distributed Computing Paradigms


    Data Mining

    Data Design

    How does the real world get translated into data? How should one structure that data to make it understandable and usable? Extends beyond database design to usability of schemas and models.

    OSDSM Specialization: Web Scraping & Crawling

    Machine Learning

    Foundational & Theoretical


    Probabilistic Modeling

    Deep Learning (Neural Networks)

    Social Network & Graph Analysis

    Natural Language Processing

    Data Analysis

    One of the "unteachable" skills of data science is an intuition for analysis. What constitutes valuable, achievable, and well-designed analysis is extremely dependent on context and ends at hand.
