Day 4 Post 7 - Lévy Flight

Source : http://en.wikipedia.org/wiki/Lévy_flight

Ohk, the fact is this, the Levy Flight is some sort of really complex function used to describe a random walk in which increments are distributed by a heavy-tailed (wtf... ohk... I wikied this too.. and I was like wtf all over again...... all I can get is there are two types of heavy tailed functions, long-tailed and subexponential... whatever they mean, I have atleast heard long tailed enough times =P... anyhow... the definition is functions which are not bound by exponential tails or something.. God!! I thought I was good at maths) probability distribution.

The thing which Levy Flight is that they are Markov procecces ( i.e. they have stochastic property.. english.. they are random and in a Markov process the future probability distribution only depends on current state).

Why am I talking about this?? .. lol.. well a) this is interesting, it is based on chaos theory... b) it is used to measure and simulate functions which are random or pseudorandom in nature..

So.. they are used from everywhere in earthquake data analysis to financial mathematics to cryptographics!!!

And .. now.. Seth Godin is proposing that they can be used to analyse behaviors of consumers.. he says that we behave a lot like such Levy Flight functions when we choose a mall, a bar or any other place we frequent.... we go to a bar.... we like it.. we stay there... we get bored after going there n number of times... and then move to another bar.. we don't find one we like... we keep moving!!

Imagine if you are doing the same in your relationships, your friendshsips and your career... LOL.. I like Wiki My Tutor, it is getting more fun everyday =)
