Get you excited about data analysis in Wakari

Walk through some basic analysis packages and wakari workflows

Kick-start your journey

MY GOALS

WHO ARE YOU?

Putting Science back in Comp Sci

• Much of the software stack is for systems programming --- C++, Java, .NET, ObjC, web

- Complex numbers? - Vectorized primitives?

• Software stack for scientists is not as helpful as it should be

• Fortran is still where many scientists end up

Why Python?

High Performance with BIG DATA

Packages for data analysis and visualization

Syntax – Gets out of your way

Community Driven

Ready for web applications, too.

• “Python is good for data cleanup, R for statistical models”

“Which is the better Data Analysis language? R or Python?” Quora. http://www.quora.com/Data-Analysis/Which-is-the-better-Data-analysis-language-R-or-Python


• “R is quirky and weird but the statisticians love it and there really isn’t any compelling reason to switch”



• “R is quirky and weird but the statisticians love it and there really isn’t any compelling reason to switch”

• “You’re running an MCMC simulation on a laptop? Perhaps you should write it in C++/FORTRAN”


Ready for DATA, and then some

Basic packages for data analysis and visualization

NumPy: The foundation of the Python Data Analysis stack

NumPy: Array-oriented

Pandas: Builds upon NumPy

Matplotlib: 2D plotting library

IPython: Interactive Python (+ in the Web)

Sharing in Wakari

• Packages IPython notebooks, files, folders, data, and environment

• Get a link

• Share that link.

Reproducible Research

“A rule of thumb among biotechnology venture capitalists is that half of published research

cannot be replicated”
