- Neuronal width (95% of second principal component) ,这句话说的什么意思啊!

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.

哥劝你不要再纠结这个问题了,实质上木有意义!我昨天首次提出这个问题时,就感觉这个问题是个无穷无尽的深渊。。。
