Hello guys. I just ran the updated tests for PL2 and they are not giving the mset order I expect.Now,the thing is, dfr's behavior is a bit hard to predict and so even if I expect a particular order ,it may give another order and still be correct.So,the only way to write correct tests for PL2 is to manually calculate the weight of the document...

Hello there, I'm trying to do lots of plots in one for-loop. But somehow ggplot does not evaluate arguments as expected. Here is an example: library(lattice) library(ggplot2) pl <- list() pl2 <- list() cDat <- as.data.frame(cbind(x1=0:100,x2=0:10,x3=1:20)) for(obs in c("x1", "x2")) { pl[[obs]] <- xyplot(cDat[,obs] ~ cDat[,"x3"], main=obs) pl2[[obs]] <- qplot(cDat[,"x3"], cDat[,obs], main=obs) } The pl list contains finally my desi...

Hello guys.I just realized that Ive not set the weighting scheme to PL2 in the tests for PL2 and so a default weighting scheme of BM25 is used. I am extremely sorry for this and am updating the tests by setting the weighting scheme to PL2. -Regards -Aarsh -------------- next part -------------- An HTML attachment was scrubbed...

Hi olly, I rewrote the test for PL2 after adding code to deal with negative weights. It passes on all backends other than inmemory . I see a different value of weight for inmemory backend. The code to calculate the lower bound is implemented in init().Please can I get some help with this ? -Regards -Aarsh -------------- next part --...

Hello guys.I have added various tests to the PL2 pull request.They are working fine. Have also added PL2 to the registry and to the java and csharp makefiles.Please do let me know what you'll think.Other than the collection frequency problem discussed on IRC, it is ready.Am now beginning work on adding code and tests for DPH to the same branc...

Hello guys.I am working on implementing the PL2 weighting scheme of the DFR framework by Gianni Amati. It uses the Poisson approximation of the Binomial as the probabilistic model (P), the Laplace law of succession to calculate the after effect of sampling or the risk gain (L) and within document frequency normalization H2(2) (as proposed by Am...

...xyplot() without arguments. Something like xyplot(x=plot1) doesn?t work either. Again we have that pl1$call is equal to xyplot() without arguments The situation is slightly different if we call the xyplot in the global environment: > plot1 <- 1:10~1:10 > pl1 <- xyplot(plot1) > pl2 <- xyplot(x=plot1) then we have > pl1$call xyplot(plot1) > pl1$call$x NULL but at least > pl2$call xyplot(x = plot1) > pl2$call$x plot1 Someone knows if in R 2.8.0 it is possible to retrieve the name of the x argument (i.e. plot1) directly from an object of class ?trellis? when...

...h the help of ggabline which does not work. The code is pl1 <- qplot(correlFunc, correlFunc.ref, data=all, log=c("xy")) pl1 <- ggabline(pl1, slope=1, intercept=0) print(pl1) ## no line in plot :( I can produce plots as I want, if I transform all values before plotting, like this: pl2 <- qplot(log10(correlFunc), log10(correlFunc.ref), data=all) pl2 <- ggabline(pl2, slope=1, intercept=0) print(pl2) ## ah, I see the line, cool! But this is definetly not nice and I cannot imagine ggplot is meant to be used like this. Furthermore, I would desperately like see ticks in the for...

hi there, i have a centos box with phpmyadmin installed, but i don't remember how i installed phpmyadmin 2.7.0-pl2. now i want to upgrade it with yum, but i don't find any phpmyadmin on my centos box. i tried: rpm -qa | grep phpmyadmi, but found nothing. is there an easy way to upgrade phpmyadmin? thanks, T.

...very long documents in the data-set collection. Also, I'm thinking of revisiting the PR of BM25+ patch and cross-check it with original BM25+ formula to spot any mistake in the implementation formula if any. Let me know of any other ideas that can possibly improve the performance of BM25+. 2. PL2+: 0.0781953 and PL2: 0.0752646 Here, PL2+ indeed does a better job at retrieving relevant documents although by a small margin. I believe this should produce much better results at scale in practical use. At this point, we might want to consider replacing PL2 with PL2+ in Xapian to put it in prac...

Hey guys,hi.:) I've finished implementing the PL2 scheme . The bounds I have implemented for it are as good as I could, given the nature of the scheme and my mathematical skills.However,tight bounds for other named DFR schemes will be easier to implement because their forumlas are quite simpler compared to PL2 . Will send in a pull request in a...
