Nabin K. Malakar, Ph.D.

I am a computational physicist working on societal applications of machine-learning techniques.

Research Links

My research interests span multi-disciplinary fields involving Societal applications of Machine Learning, Decision-theoretic approach to automated Experimental Design, Bayesian statistical data analysis and signal processing.


Interested about the picture? Autonomous experimental design allows us to answer the question of where to take the measurements. More about it is here...


I addition to the research, I also like to hike, bike, read and play with water color.

Attending MaxEnt 2011 in Waterloo, Canada

I am attending MaxEnt 2011 in Waterloo Canada.

Travelling to Waterloo was slightly involved because of the few reasons. The first one was the visa issues. At least, I am thankful that it arrived a week before my departure. Few of my friends could not make it due to the delays. Another one was that the airfare to the nearby airport was  very very expensive.  So, I travelled via Toronto (about an hour drive).
However, the best part of the airport was that the the wifi was free. So, I quickly joined the network and started calling people while waiting for my shuttle to arrive.

Here, in MaxEnt 2011, I will be presenting my work on collaborative experimental design by two intelligent agents.  The abstract of the talk can be found here ...(PDF!)
The work is the result of the overall successful (past) developments (by the Giants) of the Bayesian method of inference, experimental design techniques and the order-theoretic approach to questions. 
We view the intelligent agents as the question asking machines and we want them to be able to design experiments in an automated fashion to achieve the given goal.  Here we illustrate how the joint entropy turns out to be the useful quantity when we want the intelligent agents to efficiently learn together.
The details are in paper, which will be put in arxiv soon.

On the side notes:

Google detected right away that I "moved" to canada. So they wanted to offer

yahoo music does not seem to work!

Pandora does not work.
