* [SPARK-7402] [ML] JSON SerDe for standard param typesXiangrui Meng2015-10-132-0/+283
| | | | | | | | This PR implements the JSON SerDe for the following param types: `Boolean`, `Int`, `Long`, `Float`, `Double`, `String`, `Array[Int]`, `Array[Double]`, and `Array[String]`. The implementation of `Float`, `Double`, and `Array[Double]` are specialized to handle `NaN` and `Inf`s. This will be used in pipeline persistence. jkbradley Author: Xiangrui Meng <meng@databricks.com> Closes #9090 from mengxr/SPARK-7402.

* [SPARK-10064] [ML] Parallelize decision tree bin split calculationsNathan Howell2015-10-074-95/+97
| | | | | | | | | | Reimplement `DecisionTree.findSplitsBins` via `RDD` to parallelize bin calculation. With large feature spaces the current implementation is very slow. This change limits the features that are distributed (or collected) to just the continuous features, and performs the split calculations in parallel. It completes on a real multi terabyte dataset in less than a minute instead of multiple hours. Author: Nathan Howell <nhowell@godaddy.com> Closes #8246 from NathanHowell/SPARK-10064.

| | | | | | | | | | | | This integrates the Interaction feature transformer with SparkR R formula support (i.e. support `:`). To generate reasonable ML attribute names for feature interactions, it was necessary to add the ability to read attribute the original attribute names back from `StructField`, and also to specify custom group prefixes in `VectorAssembler`. This also has the side-benefit of cleaning up the double-underscores in the attributes generated for non-interaction terms. mengxr Author: Eric Liang <ekl@databricks.com> Closes #8830 from ericl/interaction-2.

* [SPARK-7685] [ML] Apply weights to different samples in Logistic RegressionDB Tsai2015-09-156-127/+294
| | | | | | | | | | | In fraud detection dataset, almost all the samples are negative while only couple of them are positive. This type of high imbalanced data will bias the models toward negative resulting poor performance. In python-scikit, they provide a correction allowing users to Over-/undersample the samples of each class according to the given weights. In auto mode, selects weights inversely proportional to class frequencies in the training set. This can be done in a more efficient way by multiplying the weights into loss and gradient instead of doing actual over/undersampling in the training dataset which is very expensive. http://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html On the other hand, some of the training data maybe more important like the training samples from tenure users while the training samples from new users maybe less important. We should be able to provide another "weight: Double" information in the LabeledPoint to weight them differently in the learning algorithm.

| | | | | | | | | | | | | | A few Identifiable types did override their toString method but without using the parent implementation. As a consequence, the uid was not present anymore in the toString result. It is the default behaviour. This patch is a quick fix. The question of enforcement is still up. No tests have been written to verify the toString method behaviour. That would be long to do because all types should be tested and not only those which have a regression now. It is possible to enforce the condition using the compiler by making the toString method final but that would introduce unwanted potential API breaking changes (see jira).
