Parsing Text.....Model Output

hughesfleming68

Sorry to bring this up again but I am trying to parse a small text file which is the output from a write as text operator. Could someone give me a few pointers on how to approach this? A link to a tutorial would also be very helpful.

 

The source is a weight table:-

 

23.06.2016 11:51:49 Results of ResultWriter 'Write as Text' [1]:
23.06.2016 11:51:49 1. Total number of Support Vectors: 148
Bias (offset): 0.16447

w[A-0] = -0.15679
w[B.B-0] = -0.09370
w[C-0] = -0.00203
w[D-0] = -0.01725
w[E-0] = 0.11334
w[F-0] = -0.10510
w[G-0] = 0.07406
w[H-0] = 0.11156
w[I-0] = 0.06108
w[IN-0] = 0.07957
w[J-0] = 0.20053
w[JP-0] = -0.00121
w[L-0] = 0.06061
w[M-0] = 0.17203
w[N-0] = 0.13760
w[QM-0] = 0.17374
w[V-0] = 0.07307
w[WM-0] = 0.08355

number of classes: 2
number of support vectors for class up: 74
number of support vectors for class down: 74

 

I am trying to it put into two columns with the following format and seem to be getting nowhere.

 

A        -0.15679
B.B    -0.09370 

 

regards,

 

Alex

I figured this out...finally. There are a couple of warnings but this works and sorts the weight table from LibSVM. There are a couple of warnings which I have not looked into that I would like some feedback on if anyone has the time to look but this is good enough for now.
