Markov Chain Monte Carlo

If anyone is interested in talking more about Bayesian methods and MCMC implementation, I'd be happy to put something together. - Keegan

Python, Computational Mechanics, and Information Theory

There has been interest in more discussion on a number of topics, and so i'm offering to have evening discussions on them. please sign up below so that i can get a feel for the number of people who would be attending. also, please put a preference for what day it should be.

Python

Sign up below if you'd like an introduction to basic python programming. Python is a general purpose, very flexible and useful programming language. It is used pretty extensively in scientific computing.

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.

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 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
