List of contributors to the SAMOA project.

Build Apache SAMOA

• Apache Storm

  Go to the folder where you want to store your project, and clone the new repository:

  ~$git clone http://git.apache.org/incubator-samoa.git

  ~$cd incubator-samoa

  ~$mvn -Pstorm package

  The deployable jar for Apache SAMOA will be in target/SAMOA-Storm-0.4.0-SNAPSHOT.jar.

• Apache S4 (now decommisioned after 0.4.0)

  If you want to compile Apache SAMOA for S4, you will need to install the S4 dependencies manually as explained in Executing Apache SAMOA with Apache S4.

  ~$git clone http://git.apache.org/incubator-samoa.git

  ~$cd incubator-samoa

  ~$mvn -Ps4 package

  The deployable jar for Apache SAMOA will be in target/SAMOA-S4-0.3.0-SNAPSHOT.jar.

• Apache Samza

  Go to the folder where you want to store your project, and clone the new repository:

  ~$git clone http://git.apache.org/incubator-samoa.git

  ~$cd incubator-samoa

  ~$mvn -Psamza package

  The deployable jar for Apache SAMOA will be in target/SAMOA-Samza-0.4.0-SNAPSHOT.jar.

• Local Test Mode

  If you want to test Apache SAMOA in a local environment, simply clone the repository and install Apache SAMOA.

  ~$git clone http://git.apache.org/incubator-samoa.git

  ~$cd incubator-samoa

  ~$mvn package

  The deployable jar for Apache SAMOA will be in target/SAMOA-Local-0.4.0-SNAPSHOT.jar.

Getting Started

• Download Apache SAMOA

  ~$git clone http://git.apache.org/incubator-samoa.git

  ~$cd incubator-samoa

  ~$mvn package

• Download the Forest CoverType dataset

  If you want to compile Apache SAMOA for S4, you will need to install the S4 dependencies manually as explained in Executing Apache SAMOA with Apache S4.

  ~$wget "http://downloads.sourceforge.net/project/moa-datastream/Datasets/Classification/covtypeNorm.arff.zip"

  ~$unzip covtypeNorm.arff.zip

  Forest Covertype contains the forest cover type for 30 x 30 meter cells obtained from the US Forest Service (USFS) Region 2 Resource Information System (RIS) data. It contains 581,012 instances and 54 attributes, and it has been used in several articles on data stream classification.

• Run an example

  Classifying the CoverType dataset with the bagging algorithm

  ~$bin/samoa local target/SAMOA-Local-0.4.0-SNAPSHOT.jar "PrequentialEvaluation -l classifiers.ensemble.Bagging -s (ArffFileStream -f covtypeNorm.arff) -f 100000"

  The output will be a list of the evaluation results, plotted each 100,000 instances.

Apache SAMOA is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
