* [SPARK-13355][MLLIB] replace GraphImpl.fromExistingRDDs by Graph.applyXiangrui Meng2016-02-221-2/+1
| | | | | | | | `GraphImpl.fromExistingRDDs` expects preprocessed vertex RDD as input. We call it in LDA without validating this requirement. So it might introduce errors. Replacing it by `Graph.apply` would be safer and more proper because it is a public API. The tests still pass. So maybe it is safe to use `fromExistingRDDs` here (though it doesn't seem so based on the implementation) or the test cases are special. jkbradley ankurdave Author: Xiangrui Meng <meng@databricks.com> Closes #11226 from mengxr/SPARK-13355.

* [SPARK-13295][ ML, MLLIB ] AFTSurvivalRegression.AFTAggregator improvements ↵Narine Kokhlikyan2016-02-221-15/+17
| | | | | | | | | | | | | | | | | | | - avoid creating new instances of arrays/vectors for each record As also mentioned/marked by TODO in AFTAggregator.AFTAggregator.add(data: AFTPoint) method a new array is being created for intercept value and it is being concatenated with another array which contains the betas, the resulted Array is being converted into a Dense vector which in its turn is being converted into breeze vector. This is expensive and not necessarily beautiful. I've tried to solve above mentioned problem by simple algebraic decompositions - keeping and treating intercept independently.

* [SPARK-6363][BUILD] Make Scala 2.11 the default Scala versionJosh Rosen2016-01-301-2/+2
| | | | | | | | | | | | This patch changes Spark's build to make Scala 2.11 the default Scala version. To be clear, this does not mean that Spark will stop supporting Scala 2.10: users will still be able to compile Spark for Scala 2.10 by following the instructions on the "Building Spark" page; however, it does mean that Scala 2.11 will be the default Scala version used by our CI builds (including pull request builds). The Scala 2.11 compiler is faster than 2.10, so I think we'll be able to look forward to a slight speedup in our CI builds (it looks like it's about 2X faster for the Maven compile-only builds, for instance). After this patch is merged, I'll update Jenkins to add new compile-only jobs to ensure that Scala 2.10 compilation doesn't break.

* [SPARK-9835][ML] Implement IterativelyReweightedLeastSquares solverYanbo Liang2016-01-283-1/+314
| | | | | | | | | | | | | | | | | | | | Implement ```IterativelyReweightedLeastSquares``` solver for GLM. I consider it as a solver rather than estimator, it only used internal so I keep it ```private[ml]```. There are two limitations in the current implementation compared with R: * It can not support ```Tuple``` as response for ```Binomial``` family, such as the following code: ``` glm( cbind(using, notUsing) ~ age + education + wantsMore , family = binomial) ``` * It does not support ```offset```. Because I considered that ```RFormula``` did not support ```Tuple``` as label and ```offset``` keyword, so I simplified the implementation. But to add support for these two functions is not very hard, I can do it in follow-up PR if it is necessary. Meanwhile, we can also add R-like statistic summary for IRLS. The implementation refers R, [statsmodels](https://github.com/statsmodels/statsmodels) and [sparkGLM](https://github.com/AlteryxLabs/sparkGLM). Please focus on the main structure and overpass minor issues/docs that I will update later. Any comments and opinions will be appreciated. cc mengxr jkbradley Author: Yanbo Liang <ybliang8@gmail.com> Closes #10639 from yanboliang/spark-9835.
* [SPARK-7780][MLLIB] intercept in logisticregressionwith lbfgs should not be ↵Holden Karau2016-01-266-28/+179
| | | | | | | | | | | | | | | regularized The intercept in Logistic Regression represents a prior on categories which should not be regularized. In MLlib, the regularization is handled through Updater, and the Updater penalizes all the components without excluding the intercept which resulting poor training accuracy with regularization. The new implementation in ML framework handles this properly, and we should call the implementation in ML from MLlib since majority of users are still using MLlib api. Note that both of them are doing feature scalings to improve the convergence, and the only difference is ML version doesn't regularize the intercept. As a result, when lambda is zero, they will converge to the same solution.
