MapReduce is a software framework implemented in C++ with interfaces in Python and Java introduced by Google to support parallel computations over large (multiple petabyte) data sets on clusters of computers.* The Apache* Hadoop project is a free open source Java MapReduce implementation.* Mahout is an Apache project, based on Hadoop, with an objective to build scalable, Apache-licensed machine learning libraries.
The Mahout team is initially focused on building the ten machine learning libraries detailed in Map-Reduce for Machine Learning on Multicore by seven members of Stanford�s computer science department.** These libraries, some, if not all, critical for �real� complex event processing, include;
- Locally Weighted Linear Regression (LWLR),
- Naive Bayes (NB),
- Gaussian Discriminative Analysis (GDA),
- k-means,
- Logistic Regression (LR),
- Neural Network (NN),
- Principal Components Analysis (PCA),
- Independent Component Analysis (ICA),
- Expectation Maximization (EM), and
- Support Vector Machine (SVM)
