please, I need to know What language of implementation of corn algorithm and also Is Corn system has version with java language science I need to run it in java language ,
and also I need data set used in corn system in excel files or arff files
please I wait replay

thanks in advance

Thanks.

Another question. The apriori Inverse algorithm should have a "minimum absolute threshold" as well as a "maximal support threshold"

In the documentation, the only example is:

./core01_coron.sh sample/laszlo.rcf 2 -names -alg:aprioriinverse

2 is the maxsup threshold? Is there a way to set both the min and max thresholds?

Simply redirect the output to a file:

./core01_coron.sh connect.basenum 66206 -alg:apriori > out.txt
Re: Save output to a file? by jabbalacijabbalaci, 07 Jun 2014 15:46

I tried to run some algorithm using the suggested commands in the documentation:

For example: ./core01_coron.sh connect.basenum 66206 -alg:apriori

but the results always show up in the console.

I want to save them to a file. How?

Save output to a file? by johnthebravejohnthebrave, 07 Jun 2014 14:29

I'm sorry but, I made a mistake.
As a consequence, there is no problem.
This post can be deleted.

I used Leco by : ./core03_leco.sh sample/resultat.rcf 3 -names -order -alg:dtouch -method:snow -dot -null -uc

with this data base (in rcf format)
1 1
1 1
1 0

And we obtain this lattice :
{A} (3)

^
|
|

{A,B} (0)

we should have "2" elements in the bottom concept, shouldn't we ?

Hi, I am trying to avoid the redundant rules so if my understanding was correct, the close rule type will provide all rules that apriori can provide but it excludes redundant rules which is exactly what I need. Is my understanding correct?

Also, could you please tell in brief the difference between close, zart, charm and dcharm rules?

I appreciate your help.

Thank you

Here are two execution of LeCo :

1) ./core03_leco.sh input_coron.rcf 1 -names -order -alg:dtouch -method:snow -dot -ext -dot:ext -uc -xml -of:aaa.xml ----works
2) ./core03_leco.sh input_coron.rcf 1 -names -order -alg:dtouch -method:snow -dot -ext -dot:ext -uc -of:aaa.txt ----------——does not work ?

In the second case, the aaa.txt file only contains the top and the bottom concepts, the other concepts are put into the standard output of the process but not into the file, is it normal ?

Hi,

Thanks, it's a good idea. It'd be useful, I agree. If we can find some time for it, we'll do that. Thanks for the tip.

Look at the structure of these different file formats in the "sample/" directory. You can create such a file manually or with a script. I usually write a Python script to produce an input file for Coron.

please , how can i create a database with .basenum or .rcf or .bool extension, to insert it in CORON System?

hi,

i wonder if you can create and post a video tutorial, this will help so much the members of wikidot.com.

thanks a lot for your effort.

bonjour tout le monde;

au cour de ma mémoire, j'ai besoin d'extraire des règles de connaissances à partir d'une base de cas. ceci servira pour l'adaptation et l'évolution de la base. j'ai découvert la plateforme CORON qui obéit vraiment à tout mes besoins.

mon problème est comment créer une base de cas par une table binaire et comment l'insérer sur CORON?

j'ai vraiment besoin d'une réponse et je vous remercie d'avance.
je demande pardon de ne pas écrire en anglais, j'ai quelques problèmes à rédiger mais je comprendrais bien si la réponse sera en anglais.

data base of CORON System by soumaya85soumaya85, 04 Dec 2011 22:33

There is a command line bug in the module transormer.
When using the -c option, it says that the options does not exist, but should!
This bug will be fixed in next release.

Meanwhile, a working standalone version of transformer can be found here:

http://coron.loria.fr/hot-fix/transformer.jar

Usage example:

$$» java -jar transformer.jar dataset -c auto -m interordinal

Sorry for the inconvenient!!

Hello,
please i need to use the coron platform to transform my file.txt to file.rcf ou .basenum, that's why i used the pre01-transformer but when executing this module like this exampe: "$ ./pre01_transformer.sh sample/numeric/interordinal.test -c auto -m interval -i A:0:5:i:i,B:5:9:e:i", it generates an error: "l'option -c does not exist'!!
Please I need help because i ' m bloqued in this error.
Thanks a lot.

Re: First step with Coron by boumaizaboumaiza, 09 Apr 2011 10:00

Oh, I see. Thanks a lot. I thought it'd probably be me doing something wrong…

Edit:
I just re-read your post. Yea, I was wondering why there wasn't the implementation of MRGExp that was described in the same paper with ARIMA. Turns out it just has a different name!
It's actually why I was using AprioriRare to look at the MRIs, because I'm implementing the ARIMA & MRGExp, and I was using Apriori Rare to make sure my MRGExp's output was correct, when I thought coron didn't have MRG-Exp!

Hi,

There is no problem here. Arima relies on the result of AprioriRare, but Arima needs zero itemsets too. Thus, Arima calls AprioriRare implicitly with the -all switch.

Actually, -alg:apriorirare -nonzero returns 749 MRIs and Arima reports 771 MRIs (you mixed up the numbers). But if you execute -alg:apriorirare -all, you will get 771 MRIs:

./core01_coron.sh monks.all.basenum 20 -alg:apriorirare -all

Note that if you only need the MRIs, there is a faster alg. for this (-alg:carpathiagrare). In our paper we call it MRGExp.

Best,

Laszlo
