[LLVMdev] Google's Go
Any plans to make LLVM work with Google's new language, Go? http://www.technewsworld.com/story/Go-Go-Google-Programming-Language-68622.html?wlc=1257974768&wlc=1258041607&wlc=1258047741

No, its up to them which backend they want to use. Sounds like they think that GCC is super quick compared to LLVM.

[LLVMdev] Hello!
I'm interested in contributing to LLVM, but I'm a rather bad C/C++ developer. I do most of my work in Ada and was wondering if there was a way to still contribute to something other than the Ada frontend.

[LLVMdev] array index type shuffling in GEPs
Hey folks, I am hoping that someone might be able to help me better understand this design decision: For a 64 bit target, index's into GEP's of arrays are zext up to 64 bit integers, even if the variable itself is an alloca of only i32. Similarly, on a 32 bit target, index's into GEP's are trunc'd down to 32 bits even if they ultimately reference an alloc'd

Calculating large determinants
...ture models to data. Each mixture component has p parameters (p=29 in my application) and there are q components to the mixture. The number of data points is n ~ 1500. I need to select a good q and I have been considering model selection methods suggested in Chapter 6 of @BOOK{mp01, author = {McLachlan, G. J. and Peel, D.}, title = {Finite Mixture Models}, publisher = {Wiley}, address = {New York}, year = {2001} } One of these methods involves an "empirical information matrix" which is the matrix of products of parameter scores at the observation level evaluated at t...

[LLVMdev] Quick Question...
Hey Everyone, I know that LLVM subscribes to the notion of "progress over backwards compatibility." And in that spirit, maybe someone could help me better understand the motivation behind removing the MallocInst? Is there a design doc anywhere? From a pragmatic sense, the IRBuilder's createMalloc, which was returning a MallocInst, was doing a lot of messy work for

bootstrap: stratified resampling
...k. I've only seen some side mentions in Ripley's Pattern recognition (when talking about stratified cross-validation), and Davison & Hinkley's bootstrap book when, on p. 304, they refer to some subsets having singular design matrices, and thus requiring stratification on covars. McLachlan (in his discriminant analysis book), on p. 347, differentiates between mixture sampling and separate sampling, but I can find a mention of what do when, under mixture sampling, we end up with all samples in only one group. Only Hirst (1996, Technometrics, 38 (4): 389--399) says that each bootst...

model based clustering with flexmix
Hello all, I am trying to fit a truncated mixture model and I wrote a driver for flexmix following the example in the vignette, but it doesn't work for me: it assigns all data points to one component only, e.g.: > > source('bugged.R') > > Call: > flexmix(formula = x ~ 1, k = 2, model = truncatedmodel(lower = -4, > upper = 4)) > > prior size

Help with Clustering Techniques in R
Greetings RListers, I have a data set containing two types of outcomes; success and failure. Associated with each outcome are 12 different measurements. I'm trying to find out, for example, if some of the 12 measures are associated more with success or failure or, if there's any relationship at all between the measures and the outcomes (success or failure). I don't have (as yet)

classification for huge datasets: SVM yields memory troubles
Hi I have a matrix with 30 observations and roughly 30000 variables, each obs belongs to one of two groups. With svm and slda I get into memory troubles ('cannot allocate vector of size' roughly 2G). PCA LDA runs fine. Are there any way to use the memory issue withe SVM's? Or can you recommend any other classification method for such huge datasets? P.S. I run suse 9.1 on a 2G RAM

LDA with previous PCA for dimensionality reduction
Dear all, not really a R question but: If I want to check for the classification accuracy of a LDA with previous PCA for dimensionality reduction by means of the LOOCV method: Is it ok to do the PCA on the WHOLE dataset ONCE and then run the LDA with the CV option set to TRUE (runs LOOCV) -- OR-- do I need - to compute for each 'test-bag' (the n-1 observations) a PCA
