Open, Reproducible and Exploratory Data Science
Data Science involves the application of scientific methodologies to data driven computations across a wide range of fields. As Drew Conway has clarified, it sits at the intersection of hacking/programming, math/statistics and domain specific expertise. Because data science is data- and computing-centric it requires powerful software tools. In this talk I will describe open source software tools for data science that i) are built with open languages, architectures and standards, ii) promote reproducibility and iii) are optimized for exploratory data analysis and visualization.
In particular, I will describe the Jupyter Notebook (formerly named IPython), an open-source, web-based interactive computing environment for Python, R, Julia and other programming languages. The Notebook enables users to create documents that combine live code, narrative text, equations, images, video and other content. These notebook documents provide a complete and reproducible record of a computation, its results and accompanying material and can be shared over email, Dropbox, GitHub or converted to static PDF/LaTeX, HTML, Markdown, etc. Most importantly, the Jupyter Notebook is built on top of an open architecture for interactive computing that is completely language neutral, allowing it to serve as a foundation for other data science projects and products.
Throughout the talk, I will provide examples of how IPython is being used across a wide range of fields including science, engineering, social sciences, finance, computer science, industry, publishing and journalism. Jupyter/IPython is funded through the Alfred P. Sloan Foundation, the Simons Foundation, the National Science Foundation, Microsoft and Rackspace.
