Weka is a commonly used Machine Learning suite of algorithms for Data Mining with Java. We’ve developed a Singularity container so that your Weka environment and data can now be moved cross-system on-demand, with all the benefits of the Singularity Image Format (SIF).
BootStrap: docker From: ubuntu:16.04 %post apt-get -y update apt-get -y install curl apt-get -y install unzip apt-get install -y openjdk-8-jre curl -sSL "https://prdownloads.sourceforge.net/weka/weka-3-8-3.zip" > weka.zip unzip weka.zip -d / && rm -f weka.zip* echo 'export CLASSPATH=/weka-3-8-3/weka.jar' >> /environment apt-get clean
To build the Weka container, we run:
$ sudo singularity build weka.sif weka.def
Weka builds without any setup required and its basic usage is:
$ singularity exec weka.sif java weka.classifiers.object
Toy datasets are included with this install, let’s test them out with a command:
$ singularity exec weka.sif java weka.classifiers.functions.MultilayerPerceptron \ -L 0.3 -M 0.2 -N 500 -V 0 -S 0 -E 20 -H a -t /weka-3-8-3/data/breast-cancer.arff
It also comes with a multitude of other functions, try the BayesNet function:
$ singularity exec weka.sif java weka.classifiers.bayes.BayesNet -t /weka-3-8-3/data/iris.arff -D \ -Q weka.classifiers.bayes.net.search.local.K2 -- -P 2 -S ENTROPY \ -E weka.classifiers.bayes.net.estimate.SimpleEstimator -- -A 1.0
Of course, when you run Weka you’ll want to use real data by adding the -B flag to bind your data directory into the container:
$ singularity exec -B path/to/data:/weka-3-8-3/data weka.sif java weka.classifiers.functions.[function here] \ -t /weka-3-8-3/data/yourdataset/file.arff [args]

Bills of materials or BOMs are nothing new, but they are new in the software industry. They have been part of many supply chains for decades. When you purchase a car or a pharmaceutical device, the manufacturer of those products maintains a list of...
There are many different approaches that can be taken when building software. At one end of the spectrum is the extreme caution and conservatism that’s appropriate, for example, of safety critical code used in vehicles or in real-time operating systems. At the other...
