hello, I''m booting xen on iTuner over serial console. It seems to me that it is bug that unless I explictly specify "console=com1" I get unhelpfull message "Unknown Interrupt" and halt (infinite loop). sh-2.05b# /sbin/kexec -e Starting new kernel Unknown interrupt adding "console=com1" fixes this problem for me so I doubt it I''m going to look

Buenas tardes a todos. El paquete randomForest tiene la función treesize, que es el nº de nodos. Me dan valores realmente elevados (en torno a 1000), y eso me parece extraño. ¿sabéis si es así?

Gracias Carlos y Javier, ntrees es el nº de árboles y treesize sus respectivos tamaños (nº de nodos) ntree: Number of trees to grow. This should not be set to too small ...... treesize: Size of trees (number of nodes) in and ensemble. Puse 1000 árboles (ntree=1000), si, pero la función treesize te da el nº de nodos: treesize(RFfit, terminal=TRUE) me da un vector de 1000 elementos (uno

Hello, I'm working on a problem using nested for-loops and I don't know if it's a problem with the order of the loops or something within the loop so any help with the problem would be appreciated. To briefly set up the problem. I have 259 trees (from 11 different species, of unequal count for each species) of which I am trying to predict biomass. For each tree species I have 10000

Buenas. El Paquete pdp es muy fácil de usar, pero cuando se lo aplico a mis datos me da: Error in eval(stats::getCall(object)$data) : object 'x.data' not found. Os copio abajo un ejemplo de aplicación a un RF. El mio es de un boosted regression trees (paquete gbm). No sé si esa puede ser la razón del error. En el paquete pdp no especifica que sea solo para RF, aunque en los

Muchas gracias Carlos, como siempre. Es raro que se me pasase. En su momento miré todos los argumentos del RF, como hago siempre, pero ese lo había olvidado. La verdad es que funcionaba estupendamente, pero me parecía extraño. Aunque dado que los RF no sobreajustan, no hay problema con que sus árboles sean todo lo grandes que quieras. Lo he testado con una base de datos externa y explica

When you have fairly large data, _do not use the formula interface_, as a couple of copies of the data would be made. Try simply: Myforest.rf <- randomForest(Mydata[, -46], Mydata[,46], ntrees=100, mtry=7) [Note that you don't need to set proximity (not proximities) or importance to FALSE, as that's the default already.] You might also want to use

Hi, dears, I am processing some data with 60 columns, and 286,730 rows. Most columns are numerical value, and some columns are categorical value. It turns out that: when ntree sets to the default value (500), it says "can not allocate a vector of 1.1 GB size"; And when I set ntree to be a very small number like 10, it will run for hours. I use the (x,y) rather than the (formula,data).

Hi all, We are trying to add SuSe 9.1 file server to Windows Domain. Here is our configuration. Windows 2000 Active Directory SuSe 9.1 with Samba 3.0.8 When I try to add Linux file server to windows domain using net command, net command dies with segment fault message. While starting winbind process, it dies with segment fault error message. Here is my configuration files

Hi there: recently i try to use LogicReg package for a tree model(logistics fit ) . i list my code and error below: > dim(model.dat) [1] 48000 745 > fit1 <- logreg(resp = model.dat[,745], bin=model.dat[, 9:700], type = 3, select = 3, ntrees = c(1,2), nleaves=c(1,7), ) Insufficient declaration LGCn1MAX in logreg() is 20000 LGCn1MAX should be at least 48000 Please fix and

I want to get some "simple" logic regression examples to work before exploring a hard problem. I can get results, but I'm having some problems using "cat" to save the logic regression equation to a disk file. Consider this: # Simple Logic Regression Example # efg, 23 Feb 2005 library(LogicReg) # Create simulated data with known logic equation: # "noise"

Alternatively, if you can arrive at a sensible ordering of the levels you can declare them ordered factors and make the computation feasible once again.

We just went to replace the bridge/firewall services one one server with the same on another. It's pretty simple, and I literally cloned (w/ rsync) a third server that does this onto the one that will be the new one. Then copied the /etc/sysconfig/iptables from the one being replaced, and brought it up this morning. Nope. We had to put everything back the way it was. The new one sees the two

R programming question, not machine learning, although that's the content. Apologies to all for whom the following code is eye-burning. I am using foreach() to run a simulation on a randomForest model (actually conditional randomForest ... "party" package). The simulation is in two dimensions. examining how "mtry" and "ntrees" are related in terms of predictive

Hi Mark Did you or anyone else ever find a satisfactory solution to this? Are there any phones which provide voice through the serial connection? What about the nokia card phone - does it have open source drivers?

sorry to bother everyone. i have question to get the coefficient and confidence interval in Logic Regression with Logistic model. below i list the R code X <- matrix(as.numeric(runif(400) < 0.5), 50,8) colnames(X) <- paste("X", 1:ncol(X), sep="") rownames(X) <- paste("case", 1:nrow(X), sep="") # Define expected result: Y = (NOT X1) AND X5 Y
