Thank you so much in advance for your answer,įirst of all, you need to get the data loaded. How could I run the attribute selection with such big files? So even adapting to this values, the job crashes. I looked on my machine, and the Initial Heap Size=756MB and the Maximum Heap Size= 12100MB. even with a smaller input file, that has a size of 700MB, it still crashes. I already tried to increase the memory size with -Xms1024m and -Xmx1024m. However, my input files have sizes of around 2GB so i don't manage to avoid the job to crash, getting: "Exception in thread "main" : Java heap space". With small arff input files, like the ones given as examples with weka, i manage to obtain some result. The same as in the beginning of this message: So i tried both commands but i'm not sure what is the difference between both.and which one is the one i should use for my problem: I'm starting to be a bit confused.because i just read that there is also an attribute selection filter.

What does it means? and How i could calculate the correlation coefficient i need from that output?Ģ. lines, that i don't really understand what either of them means.

However i'm not sure if the output that i obtain is the one i want. That's why in the command line i included the -z option. I would like to obtain some correlation coefficient to the class from the remaining attributes after the filtering out. I'm running the following command at the moment: And as i guess the memory will not be enough, i'm using the linux command line. My objective is to filter irrelevant or redundant instances for each different set so as to obtain a smaller number of instances correlated to the class to build afterwards causal graphs/trees.įor the first step (the filtering out) i wanted to use the correlation based feature selection algorithm. Compilingįor compiling Weka, you would issue a command like this (in the same directory as pom.I have some different datasets, mainly composed each of around 1Million numerical attributes, a numerical class and 200 instances.

In order to make Weka, and most of its packages, available to a wider audience (e.g., other software developers), we also publish on Maven Central. Though Maven can also generate far jar files, it is not considered good practice, as it defeats Maven's automatic version resolution. It allows you to use newer versions of libraries than defined by the dependent libraries (e.g., critical bug fixes), without having to modify any jars manually. Maven handles dependencies automatically, relying on libraries (they call them artifacts) to be publicly available, e.g., on Maven Central.

However, this is a nightmare, if you need to update a single library, but all you have is a single, enormous jar. Handy if you only want to have a single jar.
#WEKA JAR ONLY INCLUDE FILES YOU NEED CODE#
Whereas Ant scripts quite often create a fat jar, i.e., a jar that contains not only the project's code, but also the contain of libraries the code was compiled against. For this to work, Maven enforces a strict directory structure (though you can tweak that, if you need to). With Maven, you only specify dependent libraries, a compile and a jar plugin and maybe tweak the options a bit.

#WEKA JAR ONLY INCLUDE FILES YOU NEED HOW TO#
In Ant, you tell it where to find Java classes for compilation, what libraries to compile against, where to put the compiled ones and then how to combine them into a jar. Though its configuration file, pom.xml is written in XML as well, Maven uses a different approach to the build process. But unlike Ant, it is a more high-level tool.
