| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR copies the RandomForest implementation from spark.mllib to spark.ml. Note that this includes the DecisionTree implementation, but not the GradientBoostedTrees one (which will come later). I essentially copied a minimal amount of code to spark.ml, removed the use of bins (and only used splits), and modified code only as much as necessary to get it to compile. The spark.ml implementation still uses some spark.mllib classes (privately), which can be moved in future PRs. This refactoring will be helpful in extending the node representation to include more information, such as class probabilities. Specifically: * Copied code from spark.mllib to spark.ml: * mllib.tree.DecisionTree, mllib.tree.RandomForest copied to ml.tree.impl.RandomForest (main implementation) * NodeIdCache (needed to use splits instead of bins) * TreePoint (use splits instead of bins) * Added ml.tree.LearningNode used in RandomForest training (needed vars) * Removed bins from implementation, and only used splits * Small fix in JavaDecisionTreeRegressorSuite CC: mengxr manishamde codedeft chouqin Author: Joseph K.

* [SPARK-7691] [SQL] Refactor CatalystTypeConverter to use type-specific row ↵Josh Rosen2015-06-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | accessors This patch significantly refactors CatalystTypeConverters to both clean up the code and enable these conversions to work with future Project Tungsten features. At a high level, I've reorganized the code so that all functions dealing with the same type are grouped together into type-specific subclasses of `CatalystTypeConveter`. In addition, I've added new methods that allow the Catalyst Row -> Scala Row conversions to access the Catalyst row's fields through type-specific `getTYPE()` methods rather than the generic `get()` / `Row.apply` methods. This refactoring is a blocker to being able to unit test new operators that I'm developing as part of Project Tungsten, since those operators may output `UnsafeRow` instances which don't support the generic `get()`. The stricter type usage of types here has uncovered some bugs in other parts of Spark SQL: - #6217: DescribeCommand is assigned wrong output attributes in SparkStrategies - #6218: DataFrame.describe() should cast all aggregates to String - #6400: Use output schema, not relation schema, for data source input conversion Spark SQL current has undefined behavior for what happens when you try to create a DataFrame from user-specified rows whose values don't match the declared schema. According to the `createDataFrame()` Scaladoc: > It is important to make sure that the structure of every [[Row]] of the provided RDD matches the provided schema. Otherwise, there will be runtime exception. Given this, it sounds like it's technically not a break of our API contract to fail-fast when the data types don't match. However, there appear to be many cases where we don't fail even though the types don't match. For example, `JavaHashingTFSuite.hasingTF` passes a column of integers values for a "label" column which is supposed to contain floats. This column isn't actually read or modified as part of query processing, so its actual concrete type doesn't seem to matter. In other cases, there could be situations where we have generic numeric aggregates that tolerate being called with different numeric types than the schema specified, but this can be okay due to numeric conversions. In the long run, we will probably want to come up with precise semantics for implicit type conversions / widening when converting Java / Scala rows to Catalyst rows. Until then, though, I think that failing fast with a ClassCastException is a reasonable behavior; this is the approach taken in this patch. Note that certain optimizations in the inbound conversion functions for primitive types mean that we'll probably preserve the old undefined behavior in a majority of cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A param instance is strongly attached to an parent in the current implementation. So if we make a copy of an estimator or a transformer in pipelines and other meta-algorithms, it becomes error-prone to copy the params to the copied instances. In this PR, a param is identified by its parent's UID and the param name. So it becomes loosely attached to its parent and all its derivatives. The UID is preserved during copying or fitting. All components now have a default constructor and a constructor that takes a UID as input. I keep the constructors for Param in this PR to reduce the amount of diff and moved `parent` as a mutable field. This PR still needs some clean-ups, and there are several spark.ml PRs pending.

* [SPARK-7498] [ML] removed varargs annotation from Params.setDefaultsJoseph K. Bradley2015-05-081-1/+0
| | | | | | | | | | | In SPARK-7429 and PR https://github.com/apache/spark/pull/5960, I added the varargs annotation to Params.setDefault which takes a variable number of ParamPairs. It worked locally and on Jenkins for me. However, mengxr reported issues compiling on his machine. So I'm reverting the change introduced in https://github.com/apache/spark/pull/5960 by removing varargs. Author: Joseph K. Bradley <joseph@databricks.com> Closes #6021 from jkbradley/revert-varargs and squashes the following commits: 098ed39 [Joseph K. Bradley] removed varargs annotation from Params.setDefaults taking multiple ParamPairs

| | | | | | | | | | | | | | Params.setDefault taking a set of ParamPairs should be annotated with varargs. I thought it would not work before, but it apparently does. CrossValidator.transform should call transformSchema since the underlying Model might be a PipelineModel CC: mengxr Author: Joseph K.
