The older version of L-Measure computes w,h,d after doing the PCA
analysis first. This use to be the default setting to calculate the
w,h,and d values until the last release. However, the latest version
v4.1 which is currently available on the web,doesn't do the PCA
implicitly. Instead, it uses the original orientation of the given input
neuron to compute the w,h and d. In other words, the difference of Xmin
and Xmax values is the computed as width (considering the 95% of the
x-values and elimiting the 2.5% on either ends for outliers). Similarly,
the Y and Z axes apply to height and depth respectively. So, to
reiterate, the current version computes the w,h and d values without PCA
by simply assuming X, Y and Z axes for w, h, and d respectively. |
