Are there implementations of Machine Learning Algorithm on Map-Reduce Frameworks such as hadoop? |
|
Ridge regression/regularized least-squares classification for Hadoop/Mapreduce example at: Parallel Machine Learning for Hadoop/Mapreduce - a Python Example (disclaimer: I wrote the example and code) |
|
Also check out this paper by Andrew Ng and students which describes Hadoop versions of things "locally weighted linear regression(LWLR), k-means, logistic regression, naiveBayes, SVM, ICA, PCA, gaussian discriminant analysis, EM and backpropagation(NN)". 1
That NIPS paper was based on a single machine implementation of map-reduce, not on a viable general purpose platform. In fact, that paper was much of the inspiration for the Apache Mahout project.

Jimmy Lin and Chris Dyer recently published a book (freely available), which discusses some of the patterns used in Map-Reduce'ing a particular algorithm. |
anon, I have reverted this question since the answers are fine.
