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.


Mar 2011-Apr 2011





Graph-cut Approaches for Solving MAP Inference Queries in Multi-label MRFs

Advised by Prof. Sunita Sarawagi

This project was carried out as a part of the Advanced Machine Learning course. It involved understanding literature and implementing algorithms that employ graph-cuts for MAP inference in undirected probabilistic graphical models. The algorithms implemented were approximate energy minimization using alpha-expansion, Quadratic Pseudo-Boolean Optimization (QPBO) for inference in binary MRFs, and partial optimality in multi-label MRFs.


Aug 2011-Dec 2011





Coherence and Diversity of Web Search Results

Advised by Prof. Ganesh Ramakrishnan

The project was undertaken in lieu of course credits, and involved improving the coherence and diversity of results in the prototype web search engine Aneedo. The work includes implementing algorithms that learn how to rank web search results, and designing the interface and algorithms for faceted search in Aneedo.


Jan 2011-July 2011





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.


Sept 2010-Nov 2010

Quotes

Abhinav Maurya (:Notes to Myself:)
There is no such thing as a right decision with a wrong motive.
Decisions based solely on fear, righteousness, vengeance, or convenience are always wrong.
The greatness of literature is to be measured not by its complication but by its ambition.
A good writer seeks to be understood, but a great writer seeks to understand.
I can deal with a closed door, but not with a closed mind.
Abraham Lincoln
Always bear in mind that your own resolution to succeed is more important than any one thing.
Albert Einstein
Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius - and a lot of courage - to move in the opposite direction.
If at first an idea does not sound absurd, then there is no hope for it.
I have never belonged wholeheartedly to country or state, to my circle of friends or even to my own family. Such isolation is sometimes bitter, but I do not regret being cut off from the understanding and sympathy of other men. I lose something by it,to be sure, but I am compensated for it in being rendered independent of the customs, opinions and prejudices of others, and am not tempted to rest my peace of mind upon such shifting foundations.
Alfred North Whitehead
We think in generalities, but we live in details.
Amelia Earhart Putnam
Courage is the price that life exacts for granting peace. The soul that knows it not, knows no release from little things, knows not the livid loneliness of fear nor the mountain heights where bitter joy can hear the sound of wings.

Dudley Field Malone
I have never in my life learned anything from any man who agreed with me.
Dylan Thomas
I fell in love - that is the only expression I can think of - at once, and am still at the mercy of words, though sometimes now, knowing a little of their behavior very well, I think I can influence them slightly and have even learned to beat them now and then, which they appear to enjoy.
e e cummings
To be nobody but yourself in a world which is doing its best night and day to make you like everybody else means to fight the hardest battle any human being can fight and never stop fighting.
Earl Nightingale
A good attitude does much more than turn on the lights in our worlds; it seems to magically connect us to all sorts of serendipitous opportunities that were somehow absent before the change.
Earnest Shackleton
Men wanted for hazardous journey, small wages, bitter cold, long months of complete darkness, constant dangers, safe return doubtful. Honour and recognition in case of success. (An advertisement in 1914 that received 5000 replies)

It's better to go for it and get rejected than to never know at all. Wishing, wondering and guessing hurts more.
The best learning doesn't necessarily come from books. If you wish to learn quickly, watch those who excel in the game. Books are maps. They lead you in the right direction, but they can never replace exploration. When you were in school, you didn't just read a book. You did other things to learn that skill. Think of how that relates to all facets in life.
Be the man with scars. Learn from your mistakes and become stronger. Don't be so afraid of failure that you forget to live your life.

Lord, grant that I may always desire more than I can accomplish.
Mohandas Gandhi
Freedom is not worth having if it doesn't include the freedom to make mistakes.
You must be the change you wish to see in the world.
All through history, the way of truth and love has always won. There have been tyrants and murderers, and for a time they can seem invincible, but in the end they always fall.

The greatest thing in the world is to know how to belong to oneself.
Mother Teresa
I know God will not give me anything I can't handle. I just wish that He didn't trust me so much.
Neil Gaiman
I've been making a list of the things they don't teach you at school. They don't teach you how to love somebody. They don't teach you how to be rich or how to be poor. They don't teach you how to walk away from someone you don't love any longer. They don't teach you how to move on when the one you love walks away from you. They don't teach you how to know what's going on in someone else's mind. They don't teach you what to say to someone who's dying. They don't teach you anything truly worth knowing.
Paul Sweeney
You know you've read a good book when you turn the last page and feel a little as if you have lost a friend.
Peter Altenberg
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.
Ralph Waldo Emerson
A man is what he thinks about all day long.
Our greatest glory is not in never failing but in rising up every time we fail.
Life is short, but there is always time enough for courtesy.
Hitch your wagon to a star!
Do not go where the path may lead, go instead where there is no path and leave a trail.
Richard Bach
In order to live freely and happily you must sacrifice boredom. It is not always an easy sacrifice.
Robert Browning
Ah, but a man's reach should exceed his grasp, or what's a heaven for?
Robert Frost
In three words, I can sum up everything I've learned about life: it goes on.
There's no money in poetry, but then there's no poetry in money.
Satchel Paige
Work like you don't need the money. Love like you've never been hurt. Dance like nobody's watching.
Solomon Lefschetz
It was my lot to plant the harpoon of algebraic topology into the body of the whale of algebraic geometry.
Sun Tzu
All warfare is based on deception.
It is only one who is thoroughly acquainted with the evils of war that can thoroughly understand the profitable way of carrying it on.
He will win who knows when to fight and when not to fight.
To fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
Thomas Mann
A writer is somebody for whom writing is more difficult than it is for other people.
Tom Peters
Unless you walk out into the unknown, the odds of making a profound difference in your life are pretty low.
V S Naipaul
The writer has only to listen very carefully and with a clear heart to what people say to him, and ask the next question, and the next.
Will Durant
Education is a progressive discovery of our own ignorance.
William Blake
Use what talents you possess. The woods would be very silent if no birds sang there except those that sang best.
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.
Winston Churchill
Courage is what it takes to stand up and speak; courage is also what it takes to sit down and listen.
Zeno
The goal of life is living in agreement with nature.
