similar to: Regular expressions: retrieving matches depending on intervening strings [Follow-up]

Greeting- I have a mixed network of ms-windows, macintosh and freebsd systems. I am setting up a FreeBSD 9.0 system as a PDC using samba. I can from a FreeBSD box attach to the SMB server as a user that is defined on the Samba Server.

Dear all, Objective: I am trying to learn about neural networks. I want to see if i can train an artificial neural network model to discriminate between spam and nonspam emails. Problem: I created my own model (example 1 below) and got an error of about 7.7%. I created the same model using the Rattle package (example 2 below, based on rattles log script) and got a much better error of about

Hi R experts I have the following regular expression problem. I am writing a basic corpus retrieval program, i.e. a concordancer/function where a user enters - a set or a directory of text files to search; - a regular expression to search for in these files. I want to provide an output in which the matches of the regular expression are listed in one central column and the neighboring columns

As a follow-up to my email below: The input data frame to nnet() has dimensions: > dim(coreaff.trn.nn) [1] 5088 8 And the predictions from the neural network (35 records are dropped - see email below for more details) has dimensions: > pred <- predict(coreaff.nn1) > dim(pred) [1] 5053 1 So, the following line of R code does not work as the dimensions are

This is my first post here. As a new user of R, I was pleased to discover a simple and elegant way to compute in R the Erlang Loss Function, which I present below. INTRODUCTION The Erlang Loss Function is defined as elf(n, a ) = ( a^n/n! ) / ( 1 + a + a^2/2 + a^3/3! + ... + a^n/n!) for all real numbers a>=0 and all integers n>=0 (except that the function is undefined when BOTH n and a

Sorry for these multiple postings. I solved the problem using na.omit() to drop records with missing values for the time being. I will worry about imputation, etc. later. I calculated the sum of squared errors for 3 models, linear regression, neural networks, and support vector machines. This is the first run. Without doing any parameter tuning on the SVM or playing around with the number of

I am exploring neural networks (adding non-linearities) to see if I can get more predictive power than a linear regression model I built. I am using the function nnet and following the example of Venables and Ripley, in Modern Applied Statistics with S, on pages 246 to 249. I have standardized variables (z-scores) such as assets, age and tenure. I have other variables that are binary (0 or 1). In

Hi all, I'm running a monte carlo test of a neural network tool I've developed, and it looks like it's going to take a very long time if I run it in R so I'm interested in translating my code (included below) into something faster like Fortran (which I'll have to learn from scratch). However, as you'll see my code loads the nnet library and uses it quite a bit, and I

Dear all I am trying to compare the performances of several methods using the AUC0.1 and not the whole AUC. (meaning I wanted to compare to AUC's whose x axis only goes to 0.1 not 1) I came to know about the Mcneil Hanley test from Bernardo Rangel Tura and I referred to the original paper for the calculation of "r" which is an argument of the function cROC. I can only find the

I'm creating my own package for personal and I'm having trouble getting it to a point where R (v 2.3.1) will recognise it. I've followed two different tutorials for how to create the package structure and the DESCRIPTION file ( http://web.maths.unsw.edu.au/~wand/webcpdg/rpack.html , http://www.maths.bris.ac.uk/~maman/computerstuff/Rhelp/Rpackages.html#Lin-Lin ). I'm still getting

Dear all, I try to compare the performances of several parameters to diagnose lameness in dogs. I have several ROC curves from the same dataset. I plotted the ROC curves and calculated AUC with the ROCR package. I would like to compare the AUC. I used the following program I found on R-help archives : From: Bernardo Rangel Tura Date: Thu 16 Dec 2004 - 07:30:37 EST

I might be missing something but I thought that AUC was a measure for comparing ROC curves, so there is nothing else needed to "compare" them. The larger AUC is the higher correlation of 2 variables compared. No other measures or calculations are needed.

Hello, We're suffering from sporadic network blockage(read: unable to ping other nodes) with 1.1-pre17. Before upgrading to the 1.1-pre release, the same network blockage also manifested itself in a pure 1.0.33 network. The log shows that there are a lot of "Got ADD_EDGE from nodeX (192.168.0.1 port 655) which does not match existing entry" and it turns out that the mismatches

Please help. I found the code in the archive. The author of this script says: "The first function (seROC) calculate the standard error of ROC curve, the second function (cROC) compare ROC curves." Can some one explain to me what are the na, nn and r parameters which are used as the input to the following two functions? Thanks much in advance. > From: Bernardo Rangel Tura >

I made a quick change to syslogd(8) so that it can drop root privileges immediately after starting up. It opens up the log sockets (UNIX and network domains) and writes the PID files before dropping privs. It drops privs before openning log files and writing to users. Therefore, you would need to modify your log file permissions appropriately. As for writing to users, ttys generally are writeable

Ok, I'm having a major brain hemorrhage or something. I just can't get mrtg setup on my box. I've done it before and it's not like it's brain surgery but there's a mental block or something that I just can't get around. All I want to do is have a nice, simple graph of the traffic on the box and the gateway in the standard day/week/month/year thing. I've got the

Hi, this is a repost of a previous question - since then I have tried rebuilding my Xen0 kernel numerous times and trying different configurations, but I haven''t yet ever got a single DomU to boot so I really don''t even know what is supposed to happen, let alone how to start debugging it... Can someone please speculate on how to debug this further? It''s a gentoo

Hi All, I am trying to use a neural network for my work, but I am not sure about my approach to select a parsimonious model. In R with nnet, the IAC has not been defined for a feed-forward neural network with a single hidden layer. Is this because it does not make sens mathematically in this case? For example, is this pseudo code sensible? Thanks in advance for your help. I am sorry if this
