medium

Suppose you have a friend, very close to you, but far away in terms of distance. You have his number; and then you are also in his friend list in one of those fancy social networks around, say FB. You are in nice talking terms, have phone calls in a month or so, frequently message, etc. Suddenly one day you miss him.. miss him a lot. What will you do.. post on his wall, that you miss him or message on his cell phone. For me such sites can never give that personal touch to feelings which we seek for. I can never get a cozy feel after seeing something over my  wall. I have always felt it only as a medium to communicate and not to express. 

PS: No offences for anyone and I already beg pardon if I have hurt anyone with such remarks.

grievances

Experiences are too many though finite. Even my complaints aren't too many. I am almost happy with almost all the things around. But there are few things which if worked on, could bring a significant change in the scenario. 

For instance it is possible to appoint people who have better understanding of obvious things.. who can think and act a bit faster ..who are ready to listen patiently and understand the situation when students come in with their queries ..who know how to coordinate between two departments. (sometimes the students are treated like a ball between two departments, none ready to take responsibility, which results in lot of time wasted at students end, going from one to another) ..who are willing to be aware of what is happening outside their cabin ..who can speak the common languages comfortably (English at least). I accept we are in a state university. But if one is looking so much forward to address audience across the globe, then they should have facilities to deal with the crowd which doesn't belong to their own state. Few things which really upset me at times are like the circulars uploaded on the web are in local language. How do you expect someone not belonging to the place will be able to understand them. More in this list are officials who simply invest hours shouting on their fancy phones.. who are found listening to songs on their office machine (on speakers) and still claim the last 2 months were too hectic.. its endless...

I have no offences against any person/language/university/department. These are some general comments as an outcome of my experience of 4 years which witnessed many incidences.. though the central character was not always me. Many of these incidences would be interesting to listen (as a story). But at the same time some turn out to be so complicated that even the mentors are unable to hold on with their patience to listen till the end. 

I am very sure that no place is perfect. But at the same time there is a lot of room for improvement. Because if perfection is attained only for t reaching infinity, then for any time point t, it is always possible to achieve a better state of work at time point t+1 (if it isn't of oscillating nature :P)

Each experience makes us learn new things about the working of this place. What these incidences have in common is the following... an initial angry/frustrated/amazed reaction (depending on the person's temperament), followed by rectification process and finally the "OMG they are great" feel with which we narrate such incidences to friends and family. Sometimes what follows is a blogpost ;) :P

mistakes :P

Sometimes it feels great to accept the mistakes which we committed in our past. In fact it makes you feel lighter, by accepting the limitations of those moments and more importantly, accepting yourself as you used to be.  We keep on trying to correct the errors and after a long time into that correction process we realize that we have not only wasted lot of time but also created a brand new worse kind of mess. Best solution is to register those mistakes in your brain cells and promise yourself that you won’t repeat them.

So don’t keep on looking at the past and cursing the person that was you. Just forgive yourself and :)

PS: Don’t interpret anything serious from this note. It was just the feel I got when I tried correcting an old and badly formatted word document which was full of mathematical equations. Wish I knew Latex then ;) :P

Bayesian Inference in problem called LIFE

Ramanathan Sir has once mentioned a very nice implication of Bayesian in the real life. When we enter a new place (could be work place or educational institute), we have some prior beliefs about the people and system, as we stay there we are ought to have experience (that becomes data). That data slowly blends with the prior beliefs and we gradually come up with the posterior set of beliefs. As we go on and on, the experiences add, and we keep on updating the posterior.. and then there comes a time when (n is large) the prior beliefs are subdued by the experiences and that’s how for large n the weight is always more for the data. I liked it. 

I have a bit variation of the theory or you may say my own version or my doubt. My concern is about the data part of it. Suppose I am able to decompose my data in to two parts.. complete-past and the very latest part (recent-past). Now if my recent-past part of the data has got a bad patch, despite of the fact that the complete-past was very well behaved, then my posterior belief will obviously show a sudden negative surge (in terms of behavior) in it. Now here comes my query. How much will be the weight given to the recent past? When we have a bad experience with anyone or anything, do we remain calm enough to still account for the previous positive experiences? what remains in mind is only the negative present (or recent-past). We almost always tend to get the negative posterior belief and suddenly the weight to the complete-past decreases exponentially. Is it fair.. Do we have ways to resolve it?

What is running my mind is something like:

Posterior = W1.Prior  + W2.Data                          and for large n, W2>>W1

where  

Data = ??Recent-past + ??Complete-past

PS: Please don't take those "=" and "+" in literal sense. I ain't adding two events or sets :P

Post PS: Sorry for complicating both (life and Bayesian) :D ;)
