probabilistic neural networks
Hi, I'm working on a classification problem and one of the methods I'd like to use are neural networks. I've been using nnet to build a classification network. However I would like to have the probabilities associated with the prediction. Are there any implementations of probabilistic neural networks available in R? thanks, ------------------------------------------------------------------- Rajarshi Guha <rxg218 at psu.edu> <http://jijo.cjb.net> GPG Fingerprint: 0CCA 8EE2 2EEB 25E2 AB04 06F7 1BB9 E634 9B87 56EE ----------------------------------------------------...

choosing between probabilistic and boolean prefixes for terms
Hi all, public-inbox allows searching for git blob names (e.g. "badc0ffee") in patches. Initially, I chose to use add_prefix for probabilistic terms, since I assumed it could be a superset of what boolean searching offered. Unfortunately, it doesn't seem to be the case because stemming is interfering. So switching to boolean filtering seems to work; and it is fine for mechanical searches I plan on doing: https://public-inbox.or...

On the probabilistic distribution
...ly TL = 2-5). I have observed that 0 <= LP < 1. I am interested in testing the effects for factors D, Y, TL and for interactions TL:Y and TL:D with a view to particularly verify whether PL changed over time. I am seeking for your wise experience about the following questions: 1. Which type of probabilistic distribution am I facing? Is it normal, poisson, binomial or multinomial ? 2. What would be the most appropriate R-based approach/model to handle such a study case? Thanks in advance. Joseph [[alternative HTML version deleted]]

Probabilistic aggregation
...ta. I would like to write a semi-generalised code so that the distributions and correlation matrix could be easily changed or a larger number of distributions could be aggregated. Any help would be greatly appreciated.

?OT: Probabilistic Simulation
Sorry this may well be defined as Off Topic. I apologize in advance. I am interested in performing what I think would be a probabilistic sensitivity simulation. I've done some crude ones before in excel but I'm wondering if R can help me do it more effectively? I have a set of theoretical variables for simplicity lets use (what I think) is an easier example: I have a peg and a hole which I want to predict how often they...

Performance measure for probabilistic predictions
Hello, I'm using an SVM for predicting a model, but I'm most interested in the probability output. This is easy enough to calculate. My challenge is how to measure the relative performance of the SVM for different settings/parameters/etc. An AUC curve comes to mind, but I'm NOT interested in predicting true vs false. I am interested in finding the most accurate probability

[R-pkgs] Probabilistic neural network (PNN)
Dear useRs, I am pleased to announce the release of the new package PNN. PNN implements the algorithm proposed by Specht (1990). It is written in the R statistical language. It solves a common problem in automatic learning. Knowing a set of observations described by a vector of quantitative variables, we classify them in a given number of groups. Then, the algorithm is trained with this datasets

Looking for simpler solution to probabilistic question
Hi I have two processes which take with a certain probability (p1 and p2) x number of years to complete (age1 and age2). As soon as thge first process is completed, the second one begins. I want to calculate the time it takes for the both processes to be completed. I have the following script which gives me the answer, butI think there must be a more elegant way of doing the calculations

...we are funded by the government, and they do. They want to see someone with a compSci-related title. We are really sorry in advance if the requirement excludes you, a great hacker who doesn?t have one. Responsibilities: ----------------- Your responsibilities will be to create, adapt, and optimize probabilistic models. The data set is a large sample of purchasing behavior. You will need to demonstrate experience in bayesian modeling, ideally in a setting that resembles marketing. You will need to ?play? with parameters until we reach state-of-the-art predictive accuracy. You should be happy navigating t...

How to Plot Two Curves Into One Page
I have a R script that contain these lines for plotting: plot(foo,lwd=2,lty=3,col="red", main=""); plot(bar,lwd=2,lty=3,col="blue"); legend(0.6,0.6,c('Default','Probabilistic'), col=c('red','blue'),lwd=3); But it generate 1 file (Rplot.pdf) with two pages. Each page for 1 plot. Is there a way I can put them together in to one page? - G.V.

how to do probabilistic packet loss in kernel?
Hi, I am using iproute2 to setup fowarding, adding routes like "ip route add 192.168.1.3 via 192.168.1.2" I was wondering where in the kernel I can insert probabilistic packet loss only for forwarded packets? So that for instance I can drop 5% of all forwarded packets? I don''t need help with the actual code, just need help finding where to insert this code :) Thanks!

query time stemming and term weights
I am developping a personal/desktop search tool for which I am experimenting with doing no stemming during the indexing, but instead having a stem database (or several for different languages), used for expanding the query terms at search time. (ie: user query: flooring -> stem: floor -> final query for: [floored flooring floorings floors]) I have thought of a possible problem with

Histograms, density, and relative frequencies
...and I am hoping that someone could provide me with some advice/comments concerning my approach. I will admit that some of the underlying mathematics of the density discussion are beyond my current understanding, but I am looking into it. I have a data set (600,000 obs) used to parameterize a probabilistic causal model where each obs is a population response for one of 2 classes (either regs1 and regs2). I have been attempting to create 1 marginal probability plot with 2 lines (one for each class). Using my rather rough code, I created a plot that seems to adhere to the commonly used (althoug...

Sort by docid
...y their match relevance. The problem at hand is that I'm building a search engine for a mailing list and I would like to return matches sorted by date; ordering by docid (since the messages are indexed in chronological order) seems to be the simplest way to do so, but because I'm running a probabilistic query I don't think I can use Enquire::set_docid_order, since that will first sort by relevance and then by docid. I thought about adding the date as a value and then use set_sort_by_value, but I wonder about performance (the database contains about one million records). Any thoughts? Than...
