Abhinav Maurya
About Me
Welcome to this nook of the World Wide Web. You are visiting Abhinav Maurya's in silico existence @ IIT Bombay.
I have studied at Little Flower High School, K J Somaiya College of Science and Commerce, and VJTI. I have worked as a Lecturer at VJTI in Fall 2008, teaching undergraduate Computer Networks and Automata Theory. I have subsequently worked at Wipro Technologies as a Project Engineer (January 2009-March 2010) and then a Senior Engineer (March 2010-July 2010). I am currently pursuing graduate studies at Department of CSE, IIT Bombay. I have lived in Bombay, Delhi, and Chennai.
I occasionally dabble as a freelancer. My work has appeared in Urban Voices and Little India. I have reported for The Kala Ghoda Gazette which covers the Kala Ghoda Arts Festival held in Bombay. In 2008, I won the Book Pitch Contest, and was a runner-up in the Flash Essay Contest, both organized under the aegis of Kala Ghoda Arts Festival-2008. I am presently working on a novel which may or may not see the light of the day.
I believe in living life as if it were a book, the beautiful equanimity of its script unmarred by the event and incident embodied in the words. I believe that the pursuit of truth is more noble and precious than truth itself. I also believe that if one stands on his head long enough, he is bound to grow brainier than Chuck Norris. I love good books, gentle music, a good cup of tea, and all things in the same vein that do not require me to abandon my couch for all the worthier things in life. I do not mind being a human being, though it seems to me that being a lark or a goldfish would have been supremely better for my health and soul. I love having irrationally sensible conversations that may set forth something of precious value or confounding intrigue for me. I am intensely averse to small talk and flippancy.
I love all cities that I have lived in. Inspite of the disastrous administration and chronic violence, I love Bombay for the magnificent Gothic architecture at the heart of its urbanism. I love Delhi for its inspiring history of monuments and poetry and the chicanery it endows people with. Though I have spent only a few months in Chennai, I love that city for breathing in a language that I do not understand and for the gentle murmur of Elliots's Beach. I love being in the company of nature. I have had an idyllic childhood in a quiet suburb of Bombay, minutes from the Sanjay Gandhi National Park. I have grown up watching the monsoon mists rolling over the hills just before it begins to rain. And so on and so forth.
I suffer from bibliophily bordering on the pathological. I splurge on books till I am broke, and read them till I am blind with fatigue. I splurge on little else. One of the best ways to break the ice with me is to just whisper in my ears that you love books too. That should take care of my praetorian airs. I believe in the supremacy of the written word over the spoken one; and that the written word has much more pith, memorability and consequence than speech can ever command.
I love to travel without donning the guise of a tourist, and could easily have been a wandering minstrel or a hitch-hiking hippie in a previous life. I love music and cannot imagine life without it, though you can hardly call me a connoisseur. I especially love Indian and Western Classical and related forms such as the Ghazal and Jazz. I love arthouse cinema for harmonizing the sensibilities of literature, music, drama, and visual arts; and world cinema for acting as a proxy to the joys of actual travel. My personal favorites are Regen, 400 Blows, The Apu Trilogy, Black Cat White Cat, and The Hero. In popular culture, I love quite a few American SitComs. Favorites include Seinfeld, Friends, That '70s Show, and The Big Bang Theory.
The following thing just about sums up my entire outlook on life, except my views on delicious omlettes and intelligent fools:
If there's one thing I like, it's a quiet life. I'm not one of those fellows who get all restless and depressed if things aren't happening to them all the time. You can't make it too placid for me. Give me regular meals, a good show with decent music every now and then, and one or two pals to totter round with, and I ask no more.--Bertie Wooster in Wodehouse's The Inimitable Jeeves

Machine Learning Algorithms for Road Traffic State
Classification
Advised by Prof. Bhaskaran Raman and Prof. Saketha
Nath Jagarlapudi
In my M.Tech. thesis project, I have chosen to
explore machine learning algorithms which can be used in road
traffic state classification and which can detect and adapt to
concept drifts and change points in the wireless sensor data
stream with minimal supervision.
The project involves designing machine learning algorithms
for road traffic state classification based on changes in the
characteristics of a sensor data stream between two wireless motes
placed across the road. I developed SignalClassifier,
an efficient meta-classifier algorithm that provided higher
classification accuracy with lower time and memory overhead than
the previous FeatureClassifier method. Subsequently, I also
developed StackedSignalClassifier, a Bayesian variant of
stacked sequential learning to improve the accuracy of
SignalClassifier by using informative statistical priors based on
recent predictions.

BriMon - A Wireless Sensor Network System for
Bridge Monitoring
Advised by Prof. Bhaskaran Raman
With Jeet Patani
The project was undertaken in lieu of course credits,
and was commissioned by the Swedish Institute of Computer Science
(SICS) for further experiments. We developed a prototype of BriMon
- a wireless sensor network based system for bridge monitoring.
The design and implementation was based on Berkeley Telosb motes
and TinyOS architecture. The motes in BriMon sense acceleration
induced by a train passing over the bridge, route the sensed data
to a head node, which then piggybacks the data onto the next
passing train. The collected data can be used to do technical
analysis for structural health monitoring.

- I never dreamed of being Shakespeare or Goethe, and I never expected to hold the great mirror of truth up before the world; I dreamed only of being a little pocket mirror, the sort that a woman can carry in her purse; one that reflects small blemishes, and some great beauties, when held close enough to the heart.
- Rabindranath Tagore
- The insult and infamy that was my lot to suffer at the hands of my country were not inconsiderable in quantity and so long I had borne them with patience. In this context, I have not been able to understand clearly why I received honor from outside. I did not know that God, whom I had offered homage sitting on the Eastern shore, would extend his right arm in the western shore to accept the same... Europe has given me the garland of honor. If it carries any value, it lies in the aesthetic sense of the men of culture of that country. That has no connection with our country.

- William Hutchinson Murray
- Until one is committed, there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiative (and creation), there is one elementary truth the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, the providence moves too. A whole stream of events issues from the decision, raising in one's favor all manner of unforeseen incidents, meetings and material assistance, which no man could have dreamt would have come his way.
