# Complex Systems Summer School 2015-Tutorials

### From Santa Fe Institute Events Wiki

CSSS participants come from a wide range of disciplines. Participants are encouraged to share their knowledge by organizing their own tutorials.

You can schedule your own tutorial here, they will be held in the ESL study hall. Please do not schedule during other CSSS Lectures.

## Tutorial: Skilled action, complex systems science and the Free Energy Principle

Speaker: Jelle Bruineberg
Date & Time: June 11th, 20:00
Motivation and content: Quite some people seemed to be interested in the "Variational Approaches to Mind and Life" project that we are trying to get of the ground. Apart from this, some people were curious how philosophy relates to complex systems science. I would like to present my own work on skilled action and relate it to complex systems science. After this, I will sketch how the Free Energy Principle (the principle to be studied in the Variational Approaches to Mind and Life group) relates to this work. This is the point, where, I hope, the presentation part will stop and the brainstorm/discussion session will take over.
Prerequisite: Being open to a bit of philosophy :)
Slides: will follow
Paper: [1]

## Introduction to NetLogo

Speaker: Christine Harvey (ceharvey@mitre.org)
Date & Time: June 16th 7pm in Tutorial Room
Motivation and content: Basic introduction to NetLogo for new users/programmers. Quick overview of the screens, language and possibilities. And standard documentation practices for the model. Walkthrough editing a model.
Interested people:

## Tutorial: R, EDA, a bit of geo-mapping

Speaker: Brent Schneeman
Date & Time: TBD
Motivation and content: The "Great Circles" t-shirt design generated some interest in how it was done. I'll walk through the code showing how R can access the Google Maps API and generate great circle arcs. Along the way, we'll look at generating simple descriptive plots of a dataset that will likely resonate with you. If we're lucky, we'll be able to translate the arcs and the world map longitudinally. A teensy bit of github will also be shown.

## Python: A Crash Course

If there are particular things you'd like covered, or if you'd like to co-instruct, drop me a line (rbarnes@umn.edu). A few people have expressed interest on following up on this tutorial by teaching workshops on specific packages for networking, machine learning, and scientific computation.

## Cloud Computing Introduction

Speaker: Christine Harvey (ceharvey@mitre.org)
Date & Time: TBD, targeting third or fourth week
Motivation and content: This will cover an introduction to cloud computing using Amazon Web Services. This will review setting up an AWS account, launching an instance, logging on to the remote computing resource, and we can try to do a little something else as well. Open to suggestions!
Prerequisite: Amazon account and a credit card (compute time should cost < \$1)

## Reproducible Research with iPython Notebooks

Speaker: Christine Harvey (ceharvey@mitre.org)
Date & Time: TBD, targeting third or fourth week
Motivation and content: iPython notebooks are a great way to keep track of your analysis and track data manipulations. Ideal for anyone working with data sets and creating visualizations along the way. More details to follow! Example: http://ipython.org/_static/sloangrant/9_home_fperez_prof_grants_1207-sloan-ipython_proposal_fig_ipython-notebook-specgram.png
Prerequisite: Python Install with iPython Notebooks (other packages to be listed). Easiest install is the Anaconda Install (http://continuum.io/downloads)
Interested people:

• Glenn Magerman
• Valery
• Song Binyang
• Tolga Oztan

## Topological Data Analysis - Persistent homology

Speaker: Alice Patania
Date & Time: Friday, June 19th, 6.30pm
Content:The tutorial will be a short introduction to topological data analysis and its applications to complex systems. I will try to illustrate the utility of these class of methods in several real world examples, and give some computational tools to apply them.
Motivation: Topological Data Analysis is sensitive to both large and small scale patterns that often fail to be detected by other analysis methods, such as principal component analysis, (PCA), multidimensional scaling, (MDS), and cluster analysis. PCA and MDS produce unstructured scatterplots and clustering methods produce distinct, unrelated groups. These methodologies sometimes obscure geometric features that topological methods can capture.

## Basic examples of dummy variable use in econometrics applied to some Prof. Wooldridge datasets

Speaker: Nilton Cardoso
Date & Time: 3rd or 4th week time, TBD
Contents: Let´s go over some basic examples using Wooldridge´s datasets to illustrate the use of dummy varibales in econometrics.
Motivation: Dummy variables in econometric models can capture group/ categories effects and are very useful in estimating different patterns within the sample.
Prerequisite: Install R Studio (http://www.rstudio.com/products/rstudio/download/); selected csv data from Wooldridge data sets (http://www.cengage.com/aise/economics/wooldridge_3e_datasets/)

## Modeling With NetLogo

Speaker: Christine Harvey (ceharvey@mitre.org) and Keith Burghardt (keith@umd.edu)
Date & Time: 7:00PM, June 16
Motivation: NetLogo is a powerful tool for Agent-Based Models (ABM) due to its ease to code, simple-to-create visualization tools, and relatively fast computation capabilities. NetLogo is written in Java, which gives this modeling environment great portability at the expense of speed compared to C or Fortran.
Content: In this talk, I will be reviewing NetLogo for students with mild backgrounds in coding by describing the basic program environment, GUI interface, and ways to reduce performance issues through massive parallelization, and avoiding read/write race conditions that can crop up.
