Comparing Two Graphs

[munirfarhan]

Hi Everyone,

I am want to compare two graphs in order to check if they are similar.
I want check if one graph has similar pattern as the order.

People keep suggesting to look at Hidden Markov Model (HMM) and then apply forward-backward algorithm to compute Kullback-Leibler distance.

But I found problem with HMM is that it is a statistical model and it uses state transition probability

In my case, I have 6 discrete states and 3-Axis data. Any ideas how can i convert 3-axis data into Transition Probability Matrix?

or can some one point me towards a better alogrithm

thanks

What do you mean by "similar"?

The first step is to come up with an exact definition, then a suitable implementation often follows naturally.
