{{Complex Systems Summer School 2012}}

Use this space to organize your own after hours activities.

==Fossils and Hot Springs==

Hi, we are planning to look for fossils in the surroundings of Mora (about one hour drive from SF) tomorrow. We expect to find trilobites, maybe also ammonoids and other stuff. On the way back we'd like to stop at some hot spring resort.
Departure tomorrow saturday, at about 9:30am from the parking circle. The drivers may have to gather earlier...

If you are interested, please let us know asap so that we can organize the cars.

==Road Trip to Boulder, Colorado==

From Gareth: Hi all, I'm planning on making a trip up to Boulder, CO for the weekend. It's about a 6 1/2 hr drive from Santa Fe and I'll be renting a car. My main reason for the trip is to see a friend of mine so you might have to sort your own accommodation (camping/youth hostel/hotel). We're planning on a bit of hiking nearby. The plan is to leave straight from class on Friday evening and arrive back in Santa Fe on Sunday eve. If you're interested in splitting petrol and rental fee and joining me for some Springsteen singalongs then sign up:

==Non-linear measures of correlation==

I have been working on how to quantify the reciprocal interaction of time-series over time. I am using Recurrence Plots (http://www.recurrence-plot.tk/glance.php). If anybody is interested in discussing this method, I am willing to prepare a small tutorial on what recurrence plots are and how I have been using them.

==Order Book Dynamics: Learn how to trade in 15min==

--I'm happy to repeat this -just get in touch with me.--

If you are curious about how stocks trade and want to try your luck, I'll
be going over some of the basics with a hands-on example.

Meet at 7.30pm in main lecture hall Thursday June 7th. Please make sure
to bring your laptop.

Sanith

==Update==

Hi guys

I guess the main lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.

Here's a link to the [[software for numerical continuation|http://twr.cs.kuleuven.be//research/software/delay/notice.shtml]]. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.

(1) Please download the software DDE-BIFTOOL and unzip.

(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name

(3) Add the location of the folder to the path of MATLAB.
I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system.
Do let me know if anyone did not get this.
See you there!

Priya

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

==Using Tisean on R on OS X==
first install TISEAN, like you've done already. Make sure R is up to date (v 2.15).
you can try to install RTisean from CRAN
install.packages("RTisean"); library(RTisean); henon()
But me and Dave both got an error about some bad file name, something about con and something about a long path involving -Tmp-
Solution:
remove.packages("RTisean")
restart R
download this: http://cl.ly/0I0b2P2L311y1q0q0y0n
install it, it changes line 74 of nativeTISEAN.R which has some problems with file handling
If you are golden, then:
> henon()
V1 V2
[1,] -0.1232481 -1.030383

==A conceptual shell==

One thing that I think has been missing from this course is an explicit set of concepts and tools which we can use to relate all of the talks we've been listening to. Last fall, two other graduates students and I taught a survey course on complexity. We put together the following document, which contains one-paragraph summaries of what we felt were the 20 most important concepts that comprised the field of complexity. These were the "glue" that we used to relate all of our lectures and workshops. Most of these will probably be familiar to you, but I think they serve as a nice, concise reference and may be helpful in tying all of this information overload together. One caveat: These are works in progress and are in alphabetical rather than any logical conceptual order.

If you are curious about how stocks trade and want to try your luck, I'll
be going over some of the basics with a hands-on example.

Meet at 7.30pm in main lecture hall Thursday June 7th. Please make sure
to bring your laptop.

==Update==

Hi guys

I guess the mail lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.

Here's a link to the [[software for numerical continuation|http://twr.cs.kuleuven.be//research/software/delay/notice.shtml]]. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.

(1) Please download the software DDE-BIFTOOL and unzip.

(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name

(3) Add the location of the folder to the path of MATLAB.
I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system.
Do let me know if anyone did not get this.
See you there!

Priya

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

== About me ==
I am a 3rd year PhD student in Economics at Sant'Anna School for Advanced Studies (Pisa, Italy).
My previous academic background was also in Economics, since I did both my bachelor (Economics and Management of Innovation and Technology) and master (Economics and Social Sciences) at Bocconi University in Milan.

== Current Research Interests ==
My current research interests, in a nutshell, revolves around the idea of understanding how topological structures of financial networks influence agents' behaviors and performances in case of "critical events".
In particular, I am working on two projects:
* Macro-financial networks: I analyzed the data collected by the International Monetary Fund (IMF) about bilateral financial exposures between countries (e.g. cross-equity holdings or borrowing-lending relationships) and tested whether knowing the "position" of a country within the international financial network can tell us anything about the intesity of the crisis "felt" by that specific node/country. In particular I looked at stock market performances in (roughly) 50 countries. For details, here you have the working paper: [http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1995499 Post-Mortem Examination of the International Financial Network].
* Micro-financial networks (work-in-progress): I am analyzing high-frequency transactions data to understand whether it is possible to: 1) classify brokers' trading behaviors; 2) predict how brokers will respond to specific shocks (e.g. what would happen if Apple stocks collapse by 10% in one day?); 3) predict how the topology of the (bipartite) network will behave under different market conditions.

== Past Research Interests ==
In the past, I worked with agent-based simulations and models of epidemic diffusion.
In particular, I helped building a model for creating synthetic social mixing matrices of the Italian population
that were then used to estimate a variety of age-specific contact matrices. Those matrices were then validated against Italian serological data for Varicella (VZV) and ParvoVirus (B19) in order to see whether our simulations were able to capture the same transmission patterns of the diseases as observed in real data (at least from a qualitative point of view). If you want to know how successful we were, take a look at the published paper here: [http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1001021 Little Italy: An Agent-Based Approach to the Estimation of Contact Patterns- Fitting Predicted Matrices to Serological Data].

== Future Research Interests (???) ==
Future projects are still in a state of flux but - just to give you an idea of the topics range - those are the sorts of data I am collecting:
* Soccer data: e.g. detailed match statistics for different national leagues and international tournaments, players economic valuations over time, data about players' transfers, etc..
* Twitter data: i.e. "tweets networks"
* Music,Movies,TV series and Videogames data: e.g. user/viewer reviews, launch dates, ratings, box office revenues, etc..
* App data: e.g. iOS and Play store data on app downloads, user ratings, prices, etc..

== Expertise ==

Over the years, I managed to work with many different programming languages and I used many scientific software packages.
As far as programming languages are concerned, I did my master thesis in Java and C, while at the moment I am mainly working in Python (which became my favorite programming language by far [unless I have to resort to C for computational reasons.. ;) ]).

In terms of software packages, I used the following (ordered by proficiency): Matlab, Octave, Gretl (econometric software), STATA, R, SPSS, XLSTAT (addon for Excel) and Eviews.

I also work with many software libraries:
* in Python: networkx, numpy, scipy, pylab, mysqld, sqlite3, json, urllib, re, etc..
* in C: GSL
* in Java: Repast

== Free time ==

Before grad school (aka "when I really had free time to spare"), I used to ski and play basketball quite a lot, I was a semi-professional bowler and I had fun playing tennis table and billiards. In addition, being Italian, I also enjoyed play soccer.

==Project proposals==

=== Nonequilibrium game theory ===
My hope is to adapt some SFI-based models, by people like Crutchfield and Farmer, so that they will quantitatively or qualitatively reproduce features of real human data. Of course, that is very specific, and I'm up for all kinds of ideas in the areas of game learning, game dynamics, small group collective behavior, cognitive science, nonlinear time series, non-eq time series, etc., etc.

Meet me, Seth Frey, at dinner on Thursday and Friday.

=== Enzyme kinetics – Do enzymes just accelerate equilibrium or play an active role in chemical reactions? ===
Enzyme networks (e.g. glycolysis) and catalysts in complex mixtures (e.g. Belusov-Zhabotinski reaction) can profoundly influence the outcome of a chemical reaction system. What about a single enzyme? Biochemistry textbooks uniformly say that an enzyme accelerates a reaction without altering its outcome. Yet, the set of differential equations that generically describes enzyme catalysis has remarkable resemblance to the Roessler equations (a textbook example of a non-linear, complex system). With a fixed substrate input or a steady substrate flow, a single enzyme probably cannot affect the reaction outcome. However, sinusoidal or pulsating substrate input, substrate activation or product inhibition, coupling of two enzymes could turn the reaction pattern non-linear. For this project, the sets of equations to study are quite well established – they need to be analyzed. In contrast to some of the more ambitious ideas circulated, this task is exhaustively doable in less than four weeks.

I am Georg Weber. If you are interested in studying this problem, please find me on Tuesday over lunch or dinner (or talk to me at any other unstructured time).
=== Traffic pattern analysis - Can we estimate car velocity by only observing car counts? ===
==== Problem statement ====
Imagine you have a monitored highway section with a start and end point. At both points you count the number of cars that pass by. The question I'd like to answer / simulate / estimate is: can we make some inference about the velocity of cars although we only have their counts? This would be very useful from an engineering / economic perspective because it's much easier / cheaper to count cars instead of actually tracking them from A to B.
==== Ideas on how to approach this ====
I have some intuition about how to go about this, but these are purely statistical (think of it as birth and death process; or as particles in a system that have a certain lifetime - cars in the highway section are like particles in a system, and their velocity is just inverse proportional to their lifetime in this highway section). I would like to see if using explicit physical modeling of motion and agent-based modeling of traffic flow could shed more light on this problem.

'''Update 06/05/12:''' Just today we saw ''Takens theorem'' about how we can infer a systems structure from only observing a subset of variables. Well, it seems like that's exactly what this project is about.

If you are interested to see more about this check out the [[Georg_M_Goerg#SFI_Project:_Traffic_pattern_analysis_-_Can_we_estimate_car_velocity_by_only_observing_car_counts.3F_.3D|SFI Project]] subsection on [[Georg_M_Goerg|Georg M. Goerg]] or email me to my_3_initials_in_lowercase@stat.cmu.edu. Let's say we meet on Wednesday for lunch (or just ask me any other time you see me around).

=== Cultural Evolution - General Meet-up ===
Attention anyone who is interested in cultural evolution or applying your models/methodologies to this fabulous topic!

Let's meet at 4:15 (June 5th) in the cafe during the first "Time to work on Projects" slot. A bunch of us coalesced there tonight and figured we should all properly meet up and then bud off into different projects. Please post your potential buds below:

=== Cultural Evolution - things that look like drift but aren't ===
Lots of cultural evolution looks like drift (Bently et al 2004 'Random drift and culture change"). But what social transmission or cognitive learning mechanisms are isomorphic to random sampling with replacement from cultural inputs? In biological evolution, drift serves as a null model of sorts - one that should be ruled out before you can claim that anything more interesting is happening. However, it's not clear what the "uninteresting" type of change is for things that replicate by passing through human cognition and human social systems - like culture does. Is there even a reasonable equivalent of drift in cultural transmission? How should we go about conceptualizing and modeling the evolutionary forces at play in culture?

One candidate for a drifty-lookin' human behavior is probability matching: when people reproduce similar distributions of variation to that which they've learned from. And probability matching is rampant in human behavior (from language learning, to decision making, and even at the neural level). But I think this is a clearly different process than drift, however it still may qualify under Bentley's vague criteria - we can test that out. And there have got to be more drift-esque processes, anyone have any ideas?

If you're interested in these issues or modeling evolution (of any type of system), please give me a shout!

=== 107 Proteins in 10-15 cubic meters ===
Cells rely on proteins to perform vital metabolic and signaling functions; however, it is unclear how proteins are successfully directed to their necessary cellular location(s) in a densely-packed macromolecular environment within the cytoplasm and on the cellular membrane in a short timescale (see for example [http://www.pnas.org/content/108/16/6438.full Weigel et al., PNAS 2011]). Using the cell as a manipulatable model of complexity, one could begin to define the parameters and questions, as they pertain to prokaryotic and eukaryotic cells. If interested, please drop me a line: Sepehr Ehsani; sepehr.ehsani[at]utoronto.ca.

=== Innovation and Technological Progress ===

I noticed that a number of people mentioned that they were interested in some way in relation to innovation. I was wondering if anyone was interested in a project looking at how particular technologies progress over time and whether charting the form of successful (and/or unsuccessful) previous technologies such as the transistor, fission reactor, mobile phone, etc. in terms of either price, efficiency, or some other variable may be useful in predicting whether a current technology such as solar PV, fuel cell, or something else is following a similar trajectory. Other possible ideas might be to look at using patent, publication, or collaboration network data to reveal certain features of innovation that are not captured by other statistics, particularly for technologies that have yet to reach the market. SFI Professor Doyne Farmer has looked at some of this already in 'The Role of Design Complexity in Technology Improvement', see link: http://adsabs.harvard.edu/abs/2009arXiv0907.0036M

This could be a jumping off point for some ideas on data, methods, models etc. Just throwing the idea out there and it's welcome to completely change but if you're interested, message me (Gareth Haslam) haslam@ias.unu.edu or find me in class.

=== Space, Stochasticity, Stability; Speciation? ===

[http://tuvalu.santafe.edu/events/workshops/index.php/Xue_Feng Xue], [http://tuvalu.santafe.edu/events/workshops/index.php/Chloe_Lewis Chloe] and [http://tuvalu.santafe.edu/events/workshops/index.php/Xiaoli_Dong Xiaoli]are all working in ecosystems that experience_ a lot of unpredictability in a limiting ecosystem variables (water and/or nutrients); we see patchiness in space and time in how organisms are arranged; and we have some ideas about how the stochasticity may cause the spatial arrangements. [http://tuvalu.santafe.edu/events/workshops/index.php/Si_Tang Si] is working on the stability and robustness of ecosystems.

With enough time, this is likely to involve speciation either to express different strategies, or as a result of spatial separation.

Find any of us walking-around, or meet in the cafeteria at 4:15 June 5th.

=== Plasticity in Neural Networks ===
I've done some modeling which shows that the amount of genetic variation that accumulates at any particular metabolic gene (enzyme) in a population at any given time is a function of the network topology in which the gene is embedded, as well as the distance of the network output from an optimum. So, for instance, in a linear metabolic network, enzymes at the beginning of a pathway will tend to be more constrained (show less variation in the population) than at the end of the pathway. This makes sense given that any changes in those first genes would ripple through the system and have a greater relative effect than mutations in later genes. However, this is only true when a population is already close to an optimum. When far from an optimum, we see the exact opposite trend with more variation in the front of the pathway. This also makes sense - when far from a goal, taking bigger steps gives individuals a better chance of achieving higher fitness. The system as a whole then uses the different relative step sizes according to pathway position to "fine tune" its output.
I think these findings are quite general - at least the model we used was simple enough that it could apply to many different types of directional developmental processes. We can conceptualize these "genes" more generally as sequential steps in a developmental process with some arbitrary goal. These could be steps in a factory assembly line, major product revisions versus minor releases, or (and this is my favorite), neurons learning about their environment. I'm curious what would happen if we took a similar approach to model neural networks. Genetic variation is the raw material for evolution while neural plasticity is the raw material for learning. The question we would be trying to answer is where, within a neural network, would we expect the most plasticity given a particular network topology and distance form a learning goal.
Please contact me (Mark Longo) if this sounds interesting. I'll be available during unstructured time, or you can email mlongo@stanford.edu.

=== Robustness of complex networks ===
[[File:Zoo.png|thumb|300px|Fig. 1. Zoo of complex networks (an example). Taken from Sol´e and Valverde, 2001.]]
==== Problem statement ====
Complex networks have various properties which can be measured in real networks (WWW, social networks, biological networks), e.g. degree distribution, modularity, hierarchy, assortativity etc. Robustness of complex networks is a big question, however only some progress have been done in this direction. For example, it was shown that the scale-free networks are much more topologically robust to random attacks than random networks. Many people claim that various characteristics of complex networks will influence the robustness interdependently. The question I am interested in is how?

==== Approach ====
The idea is to generate continuous topology space of various complex networks (networks with different modularity, degree distribution, hierarchy etc) and use it to measure their robustness (see Fig. 1). There are many approaches to measure the robustness of complex networks. For example we can remove edges of vertices of a complex network graph and look at the size of a giant cluster. We can discuss other possibilities.

=== Systemic Risk in Financial Networks and/or an ABM of money/liquidity===

'''Systemic Risk in Financial Networks:''' Hypothesis: the motive to diversify risk at the level of the individual agent (i.e., for an agent to increase its connectivity) will increase systemic risk (by systemic risk I mean vulnerability of the system to widespread collapse). Point of departure is the [http://en.wikipedia.org/wiki/Forest-fire_model Forest Fire] model from statistical physics.

Key difference(s) between the physics version of the Forest Fire model, and the "economics" version of the Forest Fire model I have in mind are:
* Tree growth probability (which determines network structure) must be endogenous. Agents must be able to choose which other agents to link with.
* Probability of lightning strikes (i.e., defaults on specific loans) must also be endogenous.

I think that financial networks might exhibit self-organizing criticality in the sense that diversification will reduce the probability of lightning strikes (i.e., defaults), however over time systemic risk builds up as a result of the diversification which means that eventually a small number of lightning strikes might be enough to bring the entire system down.

'''ABM of the emergence of Money:'''
Basically, I would be interested in building an ABM of the emergence of money based around the following economic models of money developed by Nobu Kiyotaki and John Moore:
* [www.princeton.edu/~kiyotaki/papers/Evilistherootofallmoney.pdf Evil is the Root of all Money]
* [www.princeton.edu/~kiyotaki/papers/Financial-Deepening.pdf Financial Deepening]

These models take a broad view of money: "money" is any asset which is widely accepted as a medium of exchange. In these models agents manage projects which require capital investment now in order to generate a return at some point in the future and agents must trade financial promises (think debt contracts) in order to obtain the needed investment. Two key parameters of is these models (which are assumed COMMON to all agents in the above models in order to maintain analytical tractibility) are 0 < theta < 1 and 0 < phi < 1. Theta is the fraction of the future return from the project that an agent can promise to repay in the future in exchange for investment now. Phi is the fraction of the face value of a debt contract (which by construction is a contract between two agents) that can be re-sold to a third agent.

Hypothesis: In an ABM where agents differ in terms of both theta and phi, the promises of only a small number of agents will be widely traded (i.e., will serve as money).

If anyone might be interested in working on these projects, send me and email: drobert.pugh at gmail dot com

=== Price-time dynamics of contracts traded on prediction markets===
Prediction markets have been shown to outperform traditional methods of polls and opinion surveys in forecasting future events. I am interested in exploring the price-time dynamics of contracts traded on prediction markets to better understand how they are able to aggregate individual opinion to establish collective insight.

Several questions that I’m curious to probe further:
* How do ‘information shocks’ generated by news sources influence price-time trajectories?
* Can features of the underlying dynamics be characterized using a simple model?
* What is the minimum number of traders required for an accurate prediction?
On a separate note, I invite you to share your opinion regards whether “China will win the most medals at the 2012 London Olympics”, by logging into the following [https://csss12.inklingmarkets.com/user/login site] (please send me your email address and I will send you the login details).

If you haven't used a prediction market before don't worry -just follow the instructions provided in the site to 'buy' and 'sell' contracts according to your expectation.

If you are interested in the discussing any of the above questions or have other ideas related to prediction markets please get in touch with me at: sanith at mitre dot org
