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.

Arduino The Documentary

Arduino is one of the success stories of hard work and the power of collaboration in open source projects.
For curious minds who have wanted to try something  Arduino makes the way. The best part being the accessible budget in the involved projects.

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

Promote Nepal Tourism year 2011 the simplest way!

Nepal decided that 2011 should be deemed as "Nepal Tourism Year 2011". The word has not been out as much as it should have been (Well the stats will tell). So, if you are in foreign country (and are willing to promote it), you can contribute to it by a simple method:
name the wifi with promoting words to nepal tourism year 2011;
such as
or some other variations.

This is simplest way to get involved as it only involves changing your wifi name set for home network and will make few of your neighbors aware of it or might make them curious about it.

Drilling the VostoK ice core: search for life in isolated places.

Update: The Russians (may [1, 2]) have reached at the depth of 3768 meters, the surface of the sub-glacial lake. [Source]
More: here,
The origin of life is an interesting topic because addressing it affects so many philosophical aspects of present day science. As a computational scientists, we do believe in the Markov Chain Monte Carlo-like trial and error method of evolution[!], whereby the living organism is subjected to several forces of evolution and the chances of evolution depends upon the probability of survival of the evolved beings.
Other views on origin of life are open and are welcome!

The vostok ice core has been compared with other environments such as that of the deep sea of Europa or the ice volcanoes of Enceladus; the moons of Jupiter and Saturn respectively. This lake has been isolated for 14 million years. Exploration of such isolated system (without infecting them) could open up possibilities of testing various hypotheses on the origin/possibilities of life on outer/other planets.
A nice article:

Quoting BBC:
The Russians have friendly competition from US and British teams. Researchers from the British Antarctic Survey (Bas) are hoping to begin their project to drill into Lake Ellsworth in Antarctica later this year. An American crew is targeting Lake Whillans.

Coding Practice in MatLAB

MATLAB for Engineers (2nd Edition)I had a post trying to relate a good coding practice in Matlab to the bus resistance of the code.

This week, in mathworks blog,  Brett suggested three nice tutorials for matlab enthusiastic. This is equally useful to  experts as well. They are:

Open Access Physical Review X (PRX)

American Physical Society (APS) has opened up for the creative commons (cc) side of it.
Recently it announced the open access journal Physical Review X (PRX) with the aim of "covering all of physics and its application to related fields".

I think by publishing in the open access journals authors have two fold benefits. One, the readers will get unrestricted access to the articles. Second, because the readers get the easy access, the author will ultimately get more readers. Plus the authors retain the copyright of the articles. The cc3.0 license permits anyone, without the need to obtain permission from the author(s) or APS, to copy, distribute, transmit, and adapt article content, provided proper attribution is given to the author(s) and to the source of the material.

Currently there is $1500 processing fee supposedly to "cover the expenses associated with peer review, composition, hosting, and archiving."


PRX features

  • Publication in a fully open access journal
  • Broad subject coverage encouraging communication across related fields
  • Validation through prompt and rigorous peer review
  • Retention of copyright by authors
  • Liberal reuse rights through Creative Commons licensing
  • Rapid dissemination via continuous online publication
  • Full integration with the Physical Review family of publications through APS's journal platform
