Train Baum-Welch algorithm.

[Rohan Upasani]

Hello ,

I am trying to train Baum-Welch algorithm which have 3 states
as I1,I2 and Match to find similarity between two strings i.e.I will
use probabilities given by Baum-Welch algorithm into affine gap
distance .
I1 and I2 states generates the gap between strings and Match
state matches the characters so for match state observations are
<a,a> ,<b,b>..<z,z> ,<a,b>...<y,z>(match /mismatch between two
strings ) for I1 observations are <@,a>..<@,z> where @ represents
gap(gap in string 1) for I2 <a,@> .. <z,@>(gap in string 2). But I am
stuck with how to train Baum_Welch I am using excel sheet and JAHMM
(Java implementation) in Rapidminer.
So Please tell me format of input training data.

Thanks in advance.
