similar to: Random Forest:how to do an automatic rerun using only the important variables

Hi, I am doing feature selection for my dataset. The following is the extreme case where only one feature is left. But I got the error below. So my question is that do I have to use more than one features? sample.subset udomain.edu hpclass 1 -1.0 not 2 -1.0 not 3 -0.2 not 4 1.0 hp 5 1.0 hp > randomForest(hpclass ~.,

Dear all, Can anybody give me some hint on the following error msg I got with using randomForest? I have two-class classification problem. The data file "sample" is: ---------------------------------------------------------- udomain.edu udomain.hcs hpclass 1 1.0000 1 not 2 NA 2 not 3 NA 0.8 not 4 NA 0.2 hp 5 NA 0.9 hp ------------------------------------------------------------ The

Hello Han, Thanks for the response. The XML option with qemu:commandline works if the device is added during the VM creation. But I would like to hot-plug the device to the running VM. I can add the device using the command line <virsh qemu-monitor-command --hmp VM-Name device_add edu,id=edu0> But I would like to add the device using the XML file, like <virsh attach-device VM-Name

Hello, I encountered errors when building rpm on fedora33: Versions: libvirt: v6.9.0-rc2 gcc-10.2.1-5.fc33.x86_64 meson-0.55.3-1.fc33.noarch ninja-build-1.10.1-2.fc33.x86_64 binutils-2.35-11.fc33.x86_64 Steps: 1. Archive libvirt source code to ~/rpmbuild/SOURCES/libvirt-6.9.0.tar.xz 2. Copy libvirt.spec.in to ~/rpmbuild/SPECS/libvirt.spec. Then `sed -i s/@VERSION@/6.9.0/g

For the libvirt 5.8 release, I find that there is a new comment in qemu.conf: #slirp_helper = "/usr/bin/slirp-helper" It indicates that there is a slirp-helper to help setup slirp network. But I cannot find it even after I built the latest qemu(v4.1.0-1378-g98b2e3c9ab) and libvirt (v5.9.0-rc1-2-g73f91d659b). Could you please tell me where I can find that helper program? Thanks --

Hi Han, thanks for your reply. I'm using KVM as hypervisor. The versions are: Kernel: 4.5.2 Libvirt: 1.3.4-1 But its quite embarrasing... when I was answering your mail I was having a look if there is a new kernel I can build, since I have to rely on some patches. I upgraded from 4.4.3 to 4.5.2 and now libvirt doesn´t have any problem. So thanks for the heads up! Regards Alex On Tue, May

Hello, As we know, libvirt sanlock support file type storage. I wonder *if it supports network storage.* I tried *iSCSI*, but found it didn't generate any resource file: Version: *qemu-2.10 libvirt-3.9 sanlock-3.5* 1. Set configuration: qemu.conf: *lock_manager = "sanlock"* qemu-sanlock.conf: *auto_disk_leases = 1disk_lease_dir = "/var/lib/libvirt/sanlock"host_id =

Dear All, I am trying to solve the optimization problem below, but I am always getting the following error: Error in optim(rep(20, nvar), f, gr, method = "L-BFGS-B", lower = rep(0, : L-BFGS-B needs finite values of 'fn' Any ideas?

Hi, I'm currently using the R package e1071 to train naive bayes classifiers and came across a bug: When the posterior probabilities of all classes are small, the result from the predict.naiveBayes function become NaNs. This is an issue with the treatment of the log-transformed probabilities inside the predict.naiveBayes function. Here is an example to demonstrate the problem (you might need

I am now getting the occasional complaint about survival routines that are not able to handle big data.?? I looked in the manuals to try and update my understanding of max vector size, max matrix, max data set, etc; but it is either not there or I missed it (the latter more likely).?? Is it still .Machine$integer.max for everything??? Will that change??? Found where? I am going to need to go

Hallo All, I would like to apply a function to all permutations of variables in a dataframe (except the first). What is the best way to achieve this? I produce the permutations using: nvar <- ncol(dat) - 1 perms <- as.matrix( expand.grid(rep( list(1:0) , nvar ))[ , nvar:1] ) Thanks in advance Serguei Test-dataframe, comma-delimited: code,wav,w,area,gdp,def,pop,coast,milspend,agr

Hi, in R-3.0 I get the following error when calling lsfit with more observations than variables, which seems to come from an error in the formatting of the error message (note that this was not happening in 2.15.3): > nobs <- 5; nvar <- 6; lsfit(matrix(runif(nobs*nvar), ncol=nvar), runif(nobs), intercept=FALSE) Error in sprintf(ngettext(nry, "%d response", "%d

Assume a C program invoked by .Call, that returns a list. Near the top of the program we allocate space for all the list elements. (It is my habit to use "xyz2" for the name of the R object and "xyz" for the pointer to its contents.) PROTECT(means2 = allocVector(REALSXP, nvar)); means = REAL(means2); PROTECT(u2 = allocVector(REALSXP, nvar)); u =

Dear R community members and R experts I am stuck at a point and I tried with my colleagues and did not get it out. Sorry, I need your help. Here my data (just created to show the example): # generating a dataset just to show how my dataset look like, here I have x variables # x1 .........to X1000 plus ind and y ind <- c(1:100) y <- rnorm(100, 10,2) set.seed(201) P <-

Hi Team, I am exploring "edu" device in QEMU to add my own custom device. I am able to add the device using the command line. Would it be possible to add the device using XML file through libvirt? -- Regards, Bharath
