...ated to machine learning and computational intelligence. I successfully completed my *Google Summer of Code - 2011* for the *Center for the study of Complex systems - University of Michigan*. I implemented various *algorithms (ant colony, random walk etc.)* related to computational intelligence in Repast S (*Coded in Groovy, Java*) and wrote *extensive documentations and tutorial* for the related models with *literature reviews * on the topics. My *contributions to Repast S was a part of the latest release of the software*. The detailed documentation and code can be found here:http://code.google.co...

...ction again. The reason I am asking is that I just published a post online where I used a function to which I did a minor tweak (so to improve it's output for my particular case). This tweaking was just adding one line of code, to a function who's length is 187 lines of code. So instead of repasting all the function on my blog, I decided to just explain how to edit it. But I would rather have a simple code that edited the function for the reader.

Hi, Today I came upon unexpected R behaviour. I did some modelling and the result was R object, about 28MB size (nested list, with matrixes as list elements). When I was saving the session with save.image, the resulting .RData file was 300MB. There were no other large objects: >

I'm finding that my KVM images are not bootable after i reboot my host, and i've detailed my problem here.... http://serverfault.com/questions/589806/kvm-machines-unbootable-after-host-reboot Any thoughts on why? Here is a repaste of the problem: **************************************************************************************** Im finding that my KVM guests are unusable after i reboot my host.

...regressions as objects in a list. Here is the code I have written. Is there a "better/simpler" way to do this? (Ideally, I'd like the model I specify to be flexible, and to be able to use not only lm, but also rlm, etc. (I have simplified my code for this example, but I think this repasts the essential parts of what I am trying to accomplish.) ) #my code to run a regression for each "sample" (i.e."samples" 5,6,7,8,& 9), #this saves the regression results in a list called "results" y='Ozone' x=c('Wind','Temp') results=list...

...ed in Machine Learning and presently pursuing my thesis on the same. I have been selected for Google Summer of Code (GSoC) twice. During GSoC -11, I worked for the Centre for the Study of Complex Systems, University of Michigan on making evolutionary model for swarms (http://code.google.com/p/cscs-repast-demos/wiki/Mudit) and last summer, GSoC - 12, I worked on making HLA interfaces for The network simulator - 3 to aid ns-3 in distributed simulation ( http://www.nsnam.org/wiki/index.php/GSOC2012HLA). My first-degree thesis last semester was on computational cognitive modelling of artificial investo...
