==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

==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.

== Hierarchical Dirichlet Processes and the Infinite Hidden Markov Model ==

Over the past week, I've discussed Hierarchical Dirichlet Processes (HDP) and the Infinite Hidden Markov Model (iHMM) with several of you. Basically, it's the only framework I've come across, aside from Jim Crutchfield's work on the epsilon machine, that offers the diligent student the ability to estimate the hidden states generating one's data, without requiring the analyst a priori specify the number of hidden states (a very nice feature). One of the most significant differences between these approaches is Crutchfield's requires a finite alphabet, whereas HDP is defined in the context of an infinite number of base probability measures (think clustering). I believe they are both worth knowing, and I'm willing to offer a tutorial on the topics of HDP and iHHM. I'm thinking Tuesday at 8:30pm (after Scott Page's talk) in the conference room is our best bet. If you are interested, please do have a look at the following paper by Yee Whye Teh:
*[[File:HDP(2005)Teh&Jordan.pdf]]

It can get a little abstract, infinite partitions nested in infinite partitions, so try to check it out beforehand if you plan to attend. If you have any questions, fire me an email: jlong29@gmail.com

==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:

==Dancing==

Swing dancing on Monday 18th June.
Lessons from 7 to 8 P.M.
Dancing from 8 on wards.
The cost is $8 including the lesson and dancing (or $3 for the dancing). Venue: Odd Fellows Hall, 1125 Cerrillos Road. We have not yet decided on transportation. We could either take a cab or walk -- Let's try to decide during dinner.
Sign up below if you are interested:

1.Vikram -- Slightly biased towards taking the lesson. 
2. Xue -- dancing, though not a strong preference. 
3. Mark - I could use a lesson, or twelve. Do we have transportation? 
4. Chloe -- would rather walk down with everyone than skip the lesson. 
5. Aleksandra -- would try lesson, may be stay for dancing. 

PS: If you are on the edge because you want to attend the session on "Introduction to Python". I would be happy to walk you through the basics of Python at a later time. -- Vikram

PPS: how about a Dancing Python lunch tomorrow? I can do intro tutoring too. --Chloe

Other varieties --

There's a contra on the 23rd; swing dancing most Mondays; this is supposed to be a great tango town, and the drop-in-friendly beginner class on Thursday PM was good ($20, though).

[http://www.santafenewmexican.com/Sidebar/Dance_fever_in_Santa_Fe swing, salsa, tango]

We've heard great Appalachian-style folk musicians here already, but I haven't found a ceili or hoedown locally.

==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 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.

==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:

[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.
