using reserved words in R, and reuse variable names in different functions
Hi list,
I am writing several functions and running out variable names. I am using
words such as "t", "c", "matrix" to keep the notation same as formulas I am
using.
For example I have,
unnormalized <- function(t, x, y){
val <- rnorm(t, mean=x, var=y)
return(val)
}
metropolis <- function(t, c, x, y){
den1 <- unnormalized(t, mean=x, sd=y)
den2 <- unnormalized(c, mean=x, sd=y)
if(den1 < den2)
return(a)
else
return(b)
}
for(i in 1: 100...

[LLVMdev] Exception Table Padding Change
...FDEs and the GCC_except_table* labels are now different.
It looks like your goal is to keep the 32-bit pointers in the call-site table 4-byte aligned. Here is another solution, instead of having two labels at the start of the LSDA (with pad bytes between them), have no pad bytes and instead use an unnormalized uleb128 for the call-site table length. By unnormalized, I mean one with leading zeros. For instance, instead of:
.section __DATA,__gcc_except_tab
.align 2
GCC_except_table1:
.byte 0x0
.byte 0x0
.byte 0x0
Lexception1:

poly() with unnormalized values
How can I get the result of, e.g., poly(1:3. degree=2) to give me the
unnormalized integer coefficients
usually used to explain orthogonal polynomial contrasts, e.g,
-1 1
0 -2
1 1
As I understand things, the columns of x^{1:degree} are first centered
and then
are normalized by 1/sqrt(col sum of squares), but I can't
see how to relate this to what is returned by...

Howto get unnormalized eigenvectors?
Hi,
I try to calculate the angle between two first eigenvectors of different covariance matrices of biological phenotypic traits for different populations. My issue here is, that all possibilities to do so seem to normalize the eigenvectors to length 1. Although the helpfile of eigen() states, that using eigen(, symmetric = FALSE, EISPACK =TRUE) skips normalization this is (I guess) not applicable

I hope someone can help me with this. I have a function (density) which I

...you kept that opinion too yourself. There
are plenty of other reasons besides laziness or carelessness that people will
consistently error in language use, such as learning disorders, head injuries,

On the contrary, I am aware of the definition of a periodogram, and I know what
the unnormalized periodogram in the data I presented looks like. Spec.pgram()
is actually normalized too something, because it's discrete integral is not
well above the SS amplitude of the signal it computed the periodogram for. In
other words, the powers are not in units of around 4,000, which the peak wou...

description of the functions is:
prestd preprocesses the network training set by normalizing the inputs
and targets so that they have means of zero and standard deviations of

poststd postprocesses the network training set which was preprocessed
by prestd. It converts the data back into unnormalized units.
prepca preprocesses the network input training set by applying a
principal component analysis. This analysis transforms the input data
so that the elements of the input vector set will be uncorrelated. In

Mallows' distance or Earth Mover's distance in R?
Hi
I am looking for an implementation (or alternative to) Mallow's
distance or the Earth Mover's distance to compare distributions or
unnormalized distributions (signatures).
Is there an implementation in R or can somebody recommend an alternative?
Thanks

samba causing high load

when I kill it (kill -9) the load goes back to normal (0.20). Then starting

Any suggestion to what I can check for? I have tried checking the open

using glmnet for the dataset with numerical and categorical
Dear R users,
if all my numerical variables in my datasets having the same units, may I
leave them unnormalized, just do cv.glmnet
directly(cv.glmnet(data,standardize=FALSE))?
i know normally if there is a mixture of numerical and categorical , one has
to standardize the numerical part before applying cv.glmnet with
standardize=fase, but that's due to the different units in the numerical
part, right...

...than a preset value, it is more likely to be a mis-spelling word.
Thus, we search for the potential correctly spelling words. We can first
employ k-gram indexes to further limit the set of vocabulary terms, then
compute the edit distance of strings.
2) deal with synonyms. This can be done by index unnormalized tokens and
maintain a query expansion list of multiple vocabulary entries to consider
for a certain query term. A query term is then effectively a disjunction of
several postings list. Also, an alternative is to do the expansion during
index construction.

Some questions about Letor project
...letor.cc under bin/ confuses me)
3. Since RankList will be removed, according to the meeting last week,
its related information will be stored under MSet::Internal. My plan is to
create new class under MSet::Internal. That class will have two kinds of
feature vectors: normalized one and unnormalized one. Since it?s in
MSet::Internal, there is a wrapper class outside it I think. So it also
needs to provide corresponding APIs in that wrapper class. Also, the ranker
will use MSet instead of RankList. Do you have any suggestions for this
part?
