FW: neural network not using all observations
...predictions from the neural network (35 records are dropped -
see email below for more details) has dimensions:
> pred <- predict(coreaff.nn1)

So, the following line of R code does not work as the dimensions are
different.

Error: dims [product 5053] do not match the length of object [5088]
In addition: Warning message:

neural network not using all observations
...of about 0.12. I am trying to increase the predictive
power of this regression model with a neural network being careful to
avoid overfitting.
Similar to Venables and Ripley, I used the following code:
> library(nnet)
> dim(coreaff.trn.nn)
[1] 5088 8
> head(coreaff.trn.nn)

Cleaning up virt SIG related wiki pages
Hi all,
I took a little bit of stock in light of preparing the re-launch of the
Virtualization SIG as per the board decision recently and noticed that
there are quite a few old and out-of-date wiki pages lying around
In particular the following pages seem very old (Iast edited in 2007)
* http://wiki.centos.org/SpecialInterestGroup/Virtualization
* http://wiki.centos.org/SpecialInterestGroup/Virtualization/Packages
I suppose these pages should link to
http://wiki.centos.org/Manuals/ReleaseNotes/Xen4-01 and the actual SIG
description as was discussed and app...
