Areas of Research - Computer science in India

hi all,
     I am sure many people reading this will already have quite some number of admits in their hands. You must be confused on which course/institute to select. There are numerous factors that you need to consider while making this decision. The following are the factors, which i think should be taken into consideration:
  • Areas of research in the institute
  • MS vs MTech. Weigh your options and analyze the opportunity cost. Also look into long term plans like work vs phd.
  • Proximity to your home state.[may not be important for a lot of people. but it is still an important factor]
  • Food and hostel facilities.
  • peer group. Try to broaden your contact circle and distribute yourself across IIT's. All of you who like computer networks do not have to come to IITB when IITM is equally good at it. You will understand what this means once you are into your second semester of MTech.
  • Placements in all the top IIT's are almost equal. So i would give this a lesser weightage.  
Research in IIT's
  1. Indian institute of Technology Bombay
  • No of profs: 43
  • Computer networks/Sensor networks
  • Machine Learning/web mining
  • Algorithms and other theoretical aspects of cs
  • Natural language processing
  • cloud computing
  • Embedded systems
  • Compilers
2. Indian Institute of Technology Madras
  • No of profs: 25
  • Computer networks
  • Computer Architecture/ VLSI
  • Visual perception etc.
  • Distributed computing
  • Algorithms
  • Robotics 
  • computer graphics
3. Indian Institute of Technology Kanpur
  • No of profs: 22
  • Theoretical computer science
  • Graph theory
  • Algorithms
  • Quantum computing etc.
4. Indian Institute of Technology Delhi
  • No of profs: 18
  • Computer architecture
  • Algorithms and theoretical computer science

Clarification - What is the purpose of this blog??

hi all,
     Of late, there seems to be quite a bit of confusion about the purpose of this blog. Anyone who has read this blog in its entirety will understand its true purpose. This post is for those who do not have the time and interest to read it, but have all the time in the world for complaining about it. I would have loved to quote what was said about this blog, for it came from some really interesting people, thanks to the social networking sites. But i am not writing this to point fingers at them. I am glad that this blog was able to capture their attention. Nevertheless, i really find the need to issue a clarification which i am sure will be useful to the others too.

This blog does not:
  • teach you how to score 'marks' in GATE.
This blog does tell you :
  • how you can have fun during preps.
  • the importance of group studies and sharing your knowledge. 
  • some important time/schedule management techniques.
  • things that you need to support the hardwork that you do.
  • the importance of family/friends support during GATE preps.
  • Some guidelines for choosing the courses/institutes. 
If knowledge and experience were not to be shared, we would still be reinventing the wheel. That is precisely the point of this blog.

Further clarification:
The authors of this blog do not believe that they have achieved something unachievable(as suggested by someone). The authors of this blog do not contribute for the sake of popularity or such simple minded things( we already have a lot of it. lol).  We write here to help/motivate people and that makes us happy.

P.S : Dear GATE aspirants, this post is not for you. please do not get offended by this.

POST-RESULT PHASE.

Hello friends,

My name is Pawan, the new contributor (thanks pk! :) ).
The results are out, you know your rank. You want to know how to proceed from now on.
There are two important steps you need to think about:
1. Decide if you want to do a research oriented programme (M.S) or a course-oriented programme (M.Tech)
2. Decide on your areas of interest. You must know them by now.

A little more on the first point: A course-oriented programme is much like B.Tech and you explore the breadth of computer science. Typically, you will have to take around 10 courses spread over 2 to 3 semesters. For a research oriented programme on the other hand, you need to take lesser courses, and spend most of your time in doing research in a domain. As in, you will have to read the literature, find out what problems are feasible to be addressed and then solve one (or more than 1) of them. You explore the depth here. So, the purposes are different. See which one of these purposes better suits you.

Opting for a M.S or M.Tech programme is crucial, a wrong choice can prove very costly. Also, you would not want to be stuck in an area which does not interest you. The caveat here is that both the decision points mentioned above must be exercised with proper judgment.

To know what all programmes are available at every IIT and IISc here is a pointer:"http://karthrags.wordpress.com/2009/03/30/iit-pg-admissions-part-2-the-interviews/".
Don't get stingy over applications. Even if you apply for one or two more than required, its okay! They might come in handy as back-ups when things don't go your way.

Lastly, "GATE results are out. I bagged a good rank. Now I can breathe easy!" SAYS WHO? NO YOU CAN'T. You will be put in a class of 60-80 students who have performed as good as you have. The competition will be high. If you relax, you will become rusty by the time you enter. So a week (or two) of relaxation is fine. But after that, patch up things, fill in the gaps, if you felt your GATE prep was incomplete, finish it. For those who are thinking about M.S programmes, there are written tests and interviews. They are not cakewalks. Those test how strong your ground floor is. So basics must be at fingertips. Please don't forget after doing all this hard-work in securing a good score in GATE, the last thing you would want to do is mess up your interviews/written tests. So pull yourself together, and keep it sturdy for few more months.

I shall get back on more, but that's all for now.

14th Feb : D-Day

With 14th Feb fast approaching, you must be in high spirits. Couldn't they select a better day for conducting the examination. Well lets not think about that. Here are some points that might just come in handy on the D-Day


Day before the Examination


  • Have a few chocolates, ice creams etc. and try to keep yourself cool and composed.
  • Prepare a list of inventories that you should take to the exam hall. This list includes Hall ticket, 2 Pencils, Erasers, Sharpener, a pen, 2 calculators( Advanced + Basic one), lucky kerchief etc.
  • Decide on the mode of transport and have a back-up plan as fail-safe. 
  • Do not forget to think about the worst thing that might happen and develop the mental strength to overcome that. Expect a really tough paper. If the paper turns out easy, you win. If it is tough, then too u win.
  • Revise all the topics. Do not try to remember them. Just browse through the material you have. Do not criticize yourself if you are not able to remember certain things.  Because it happens !!
  • May be you can go to your terrace(or some lonely place) and have a peaceful few mins there.  
On the Day of the Examination
  • Reach the Examination hall 1hrs(ideally 1.5 hrs) before the examination time. This is very essential. After all, who can take up the examination in a surrounding that one does not feel comfortable in.
  •  Take one of your reference books(preferably a small one) so that you can get into the rhythm (warming up) well before the exam starts. Do not forget to leave the reference material outside the exam hall.
  • Once you enter the exam hall, check your pockets for unwanted material. Also check if you have all the necessary items.
During the Examination
  • Try to remain flexible in your approach to answering the paper. If your strategy doesn't work, realize that it JUST DOESNT WORK. Try to adopt a different strategy before it is too late.
  • Quite often people(like me) tend to self-criticize themselves during the examination. Some even think about what they should have done in the past. Some have the urge to think about some concept(not asked in the paper) that they studied 2 days back. Such Things SHOULD BE AVOIDED.
  • If the paper turns out to be Really Tough, do not lose hope.  "If it is tough for u, it will be tough for the others too". Sooner one can understand this fact, better is the possibility of him/her emerging out successful. 
  • Last but not the least, mark all the answers properly. IF you mis-mark 1 answer, all the following answers will also go wrong( marking the answer for Q37 on Q38's slot will shift all your answers by 1 slot).
  • Ensure that you darken the bubbles properly. IF you are unsure, erase it and mark it again. Sharpen your pencil from time to time. Most likely you wont realize that it has gone blunt

Wishing you all Success in GATE 2010. More than anything, think of this exam to be a game and Enjoy it !!

Which Subjects to Concentrate on ?

As u all are already in the Revision phase, u must be confused which subjects to concentrate on. You can look at the areas where IITG is good at. Ashok Gautham has done some research on this, which i am sure will be useful. Here is a LINK to his blog.

Make sure u dont read much of new topics. Just concentrate on perfecting what u have already learned.

What Next??

"I have studied with all my might over the past 5 months."
"I am well versed in 10 subjects."
"I have been getting within the top 100 ranks in the mock tests."

"I am better than my friends in most of the subjects."

All these statements do not make any sense if you are not able to perform in the 3hrs of the final Examination. All that matters here is your performance & if you dont give that, you just become one of the losers (doesnt matter if you've worked hard or not).

Preparation is like a pipeline(the computer architecture one ;)). What u feed into the pipe is your hardwork. what you get as the output is the degree of your success. More the hardwork u feed in, the better will be the success rate. That is not all, people forget about what happens inside this pipe. This is where i would place the purpose of this post.

It is really pathetic to lose out on achieving success, inspite of the enormous hardwork you ve done. Yes, it does happen at times. what happens if the pipe has a hole? what happens if the pipe has lesser capacity? Yes you ve gotta build this pipe such that your hardwork doesnt spill mid-way inside the pipeline.

Now again this pipeline can be thought to be made up of many connecting pipes. First, the "Revision" pipe. Second, the "management" pipe. Eventually your outcome can only be as large as the smallest pipe(bottleneck). ie, if your Revision is fool-proof and your management skills are pretty bad, then dont expect a 100% success. Similarly, having great management skills without revising the concepts might be of no use. In this post i just quote some of the management techniques that we came up with during our GATE preparation.

You are given say, 65 questions. Which ones do i answer first? say i start from the last, what if i am not able to answer 10 questions in a row; it sure will affect my confidence. what should i do? Now just think. If you are in such a situation during ur GATE exam. Here are some strategies tested by us. First, the one proposed by karthik. Once u receive ur paper, just scan the paper with a neutral view(dont look forward for questions from subjects of ur interest). scan them one by one and look out for the easy ones that require the least time to answer. Remember, in GATE papers such questions will always be there. Note: there might be questions that are very familiar to u but time consuming. just tick mark them and dont answer them for now. At the end of the FIRST PASS, you wud ve answered all the free hits. Now go for a second PASS, where u answer the questions u had marked previously. ie those which u know but are time consuming. Then go for a THIRD PASS, attack the tougher problems, these are just icing on the CAKE. u get them, its gr8. u dont get them, dont worry, after all those taking GATE are of ur caliber only. It wud be tough for them too. If u spend more than 3 mins on a question, u shud know, it is a TIME KILLER. Immediately skip to the next question. I know it is difficult to skip. But this can be mastered with a little bit of practise. This Strategy can only be used in GATE if u have answered atleast 5 papers before using the same.

Second, this is my own strategy. Start answering from the first, one mark questions. These are simpler and can be finished soon. So the strategy is to finish them within 30 mins after the start of the exam. Now start the paper from the last. (ie) the linked answer questions(questions that do not hav negative marking, something that shouldn be missed). The logic behind this is that, we are better suited to answer them when we are calm rather than postponing it till the end. Now we can proceed to answer the center part of the paper. This strategy has its own flaws. I also tried the alternate logic of answering the questions from the subject that i like the most. ie Networks. Then move on to answer all questions from say, TOC. But i should mention, it didnt work out well as i expected it to.

Third, this is again something that i came up with. The Guessing strategy. What are we writing the exam for? Marks. I am not that kind, who says i wont take up the marks that i dont deserve. I am not the kind like anish and pawan who only mark an answer if they are 100% sure. I was always ready to go for them as long as they dont get me into trouble(negative marking). There was a time when i was able to eliminate 2 out of the 4 choices. Now i have to choose 1. I usually went for such question. Yes i used to take a guess. :D. More often than not, u get many such questions. There is a possibility that this might back fire. Coming back to the strategy, mark ur guesses on the question paper, like say with a "G" besides the question. Dont mark them on the OMR sheet. after u complete the paper, take a percentage(like 10 %) of the questions u have correctly answered(say i answered 40 questions, then i can guess 4). U ve gotta mark only those number of guesses. Now from all the G's u have marked, select the most promising "G" questions and mark them. Another logic here is that if u get even one of the 5  G questions right, it will cover up for the rest. (ie) 2 * 1(correct) - .5 * 4(wrong ones) = 0.

It is expected that u figure out ur own strategy and practice it over time. It is possible that the strategy suitable for me doesnt work well for u. Well, which strategy did i finally use in my GATE. thats the subject of my next post. :)
