How to interpret norm_info…MVN.dat

[Andrew W]

Hi,

Just to double check, when viewing the norm_info…MVN.dat file, is the dimensionality to open this the number within the filename? And then once opened, the first list is the means, and the second list the variances?

My dimensionality is 750 (I have an output layer of 250 units (features are 250 mgcs, 750 dmgc)) and am trying to retrieve the means and variances for the 250th unit.

Thanks

There is no need to specify dimension to view the file, just use below command:
$SPTK/bin/x2x +fa norm_info…MVN.dat > temp.txt

‘temp.txt’ file then contains exactly double the number of values as the dimension shown within the filename.

First N values represent means and the next N values represent variances.

In your case, it should have 500 values. To extract the mean and variance of 250th unit, you need to consider 250, 500th lines for mean and variance respectively.
