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,

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:

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.

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.
Thank you,

?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

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?

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

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?
