Hello, I am attempting to use elasticnet to classify a number of documents. The features are words. The data is coded into a matrix with each document as a row and each word as a column. The data is binary, with {0,1} indicating the presence of a word. I want to use the cross validation function of elasticnet (cv.enet). However, when the code selects a random subset of the data for a given

Dear all, I am using modified LARS algorithm (ref: The Adaptive Lasso and Its Oracle Properties, Zou 2006) for adaptive lasso penalized linear regression. 1. w(j) <- |beta_ols(j)|^(-gamma) gamma>0 and j = 1,...,p 2. define x_new(j) <- x(j)*w(j) 3. apply LARS to solve modified lasso problem out.adalasso <- lars(X_new,y,type="lasso") or enet(X_new,

Hi all: Glad to meet you!! My name's Zhang Fan, a Phd Student from Nankai University, China. I have been doing the information retrieval research work for 3 years. I have several papers published in the top-tier computer science conferences such as WSDM, VLDB, CIKM and ACL. I have many years of coding experiments and participated several projects about search engines. I want to take part in

Hi all: As I have gone through the The Xapian-devel Archives, it seems many people would like to do the project "weight schemes" and few would like to do the CJK project. I am a native speaker of Chinese and I learned a little Korean and Japanese, so if possible, I would like to apply this projects too.

Dear R users, I have problem with extracting coefficients from a object. Here, X (predictor)and Y (response) are two matrix , I am regressing X ( dimensions 10 x 20) on each of columns of Y[,1] (10 x 1) and want to store the coefficient values. I have performed a Elastic Net regression and I want to store the coeffcients in each iteration. I got an error message . I do not

Dear R users,   I am new user for elastic net. I am trying to use elasticnet library. I have marker data with 359 markers and 168 samples, and response is metabolites. I am trying to do regression between a metabolite and markers.  But i am getting the following error:   > en<-enet(marker,as.numeric(vio),lambda=0.5,normalize=FALSE,intercept=TRUE) Error in one %*% x : requires numeric

Dear R user, I am looking for a code on double cross validation in LASSO , one for optimizing the parameter and other one is for MSEP. If any one have it, please foroward to me. I am using different package like LARS, chemometric etc. Thanks in advance Alex [[alternative HTML version deleted]]

Hi,   I'm using lars package to run some regression analysis and my doubt now is how can I predict my model to another dataset? Let me explain a little better: I have a dataset from which I withhold some data. With the data that wasn't withheld, I create the model. Now, what I'm not being able to do is apply the model back to the data that I withheld. Any suggestions?   Here it goes

Hi Everybody! I must start with a declaration that I am a sparse user of R. I am creating a credit scorecard using a dataset which has a variable depicting actual credit history (good/bad) and 41 other variables of yes/no type. The procedure I am asked to follow is to use a penalized logistic procedure for variable selection. I have located the package "glmnet" which gives the complete

Hi all, I want peer-peer communication between two clients (soft phones) both are behind NAT.I have an accounts with SIP proxy for two clients. To communicate these two clients do i need to use Asterisk ? As per my understanding Asterisk acts like Gateway where conventional phone calls data transfer into internet voice calls. If am wrong please correct me . Thanks, Raghav.

Hi, we recently switched from Imap-Uw to Dovecot as a pop3 server. I was wondering why people who have the flag 'Leave messages on server' in their email client (Outlook, Outlook Expres) that they receive duplicates of their stored mail? Is it because Dovecot doesn't know that the messages has already been popped by Imap Uw or is the email client which thinks there are new messages

You are right, maintainer does keep a list of model's packages.

Can I use step function if my variables have a

Dear R-users I'm trying to use lasso in lars package for subset regression, I have a large matrix of size 1000x100 and my aim is to select a subset k of the 100 variables.
