Update isotonic regression #1

mengxr · 2015-01-30T21:27:22Z

@zapletal-martin I made the following change:

update isSorted, which always returns true.
compress points if they have the same prediction, where we only keep the two boundary point
update tests
a. For the first test, the previous expected value is wrong. I copied sklearn code to produce the correct value.
b. Set partitions to 2 in sc.parallelize, so we can test merging two results
c. Since the predictions are compressed, I updated the expected result

Update isotonic regression

In RDDSampler, it try use numpy to gain better performance for possion(), but the number of call of random() is only (1+faction) * N in the pure python implementation of possion(), so there is no much performance gain from numpy. numpy is not a dependent of pyspark, so it maybe introduce some problem, such as there is no numpy installed in slaves, but only installed master, as reported in SPARK-927. It also complicate the code a lot, so we may should remove numpy from RDDSampler. I also did some benchmark to verify that: ``` >>> from pyspark.mllib.random import RandomRDDs >>> rdd = RandomRDDs.uniformRDD(sc, 1 << 20, 1).cache() >>> rdd.count() # cache it >>> rdd.sample(True, 0.9).count() # measure this line ``` the results: |withReplacement | random | numpy.random | ------- | ------------ | ------- |True | 1.5 s| 1.4 s| |False| 0.6 s | 0.8 s| closes apache#2313 Note: this patch including some commits that not mirrored to github, it will be OK after it catches up.

…the lineage The related JIRA is https://issues.apache.org/jira/browse/SPARK-4672 Iterative GraphX applications always have long lineage, while checkpoint() on EdgeRDD and VertexRDD themselves cannot shorten the lineage. In contrast, if we perform checkpoint() on their ParitionsRDD, the long lineage can be cut off. Moreover, the existing operations such as cache() in this code is performed on the PartitionsRDD, so checkpoint() should do the same way. More details and explanation can be found in the JIRA.

Addition of a very limited number of local matrix manipulation and generation methods that would be helpful in the further development for algorithms on top of BlockMatrix (SPARK-3974), such as Randomized SVD, and Multi Model Training (SPARK-1486). The proposed methods for addition are: For `Matrix` - map: maps the values in the matrix with a given function. Produces a new matrix. - update: the values in the matrix are updated with a given function. Occurs in place. Factory methods for `DenseMatrix`: - *zeros: Generate a matrix consisting of zeros - *ones: Generate a matrix consisting of ones - *eye: Generate an identity matrix - *rand: Generate a matrix consisting of i.i.d. uniform random numbers - *randn: Generate a matrix consisting of i.i.d. gaussian random numbers - *diag: Generate a diagonal matrix from a supplied vector *These methods already exist in the factory methods for `Matrices`, however for cases where we require a `DenseMatrix`, you constantly have to add `.asInstanceOf[DenseMatrix]` everywhere, which makes the code "dirtier". I propose moving these functions to factory methods for `DenseMatrix` where the putput will be a `DenseMatrix` and the factory methods for `Matrices` will call these functions directly and output a generic `Matrix`. Factory methods for `SparseMatrix`: - speye: Identity matrix in sparse format. Saves a ton of memory when dimensions are large, especially in Multi Model Training, where each row requires being multiplied by a scalar. - sprand: Generate a sparse matrix with a given density consisting of i.i.d. uniform random numbers. - sprandn: Generate a sparse matrix with a given density consisting of i.i.d. gaussian random numbers. - diag: Generate a diagonal matrix from a supplied vector, but is memory efficient, because it just stores the diagonal. Again, very helpful in Multi Model Training. Factory methods for `Matrices`: - Include all the factory methods given above, but return a generic `Matrix` rather than `SparseMatrix` or `DenseMatrix`. - horzCat: Horizontally concatenate matrices to form one larger matrix. Very useful in both Multi Model Training, and for the repartitioning of BlockMatrix. - vertCat: Vertically concatenate matrices to form one larger matrix. Very useful for the repartitioning of BlockMatrix.

…l adjacent violators algorithm This PR introduces an API for Isotonic regression and one algorithm implementing it, Pool adjacent violators. The Isotonic regression problem is sufficiently described in [Floudas, Pardalos, Encyclopedia of Optimization](http://books.google.co.uk/books?id=gtoTkL7heS0C&pg=RA2-PA87&lpg=RA2-PA87&dq=pooled+adjacent+violators+code&source=bl&ots=ZzQbZXVJnn&sig=reH_hBV6yIb9BeZNTF9092vD8PY&hl=en&sa=X&ei=WmF2VLiOIZLO7Qa-t4Bo&ved=0CD8Q6AEwBA#v=onepage&q&f=false), [Wikipedia](http://en.wikipedia.org/wiki/Isotonic_regression) or [Stat Wiki](http://stat.wikia.com/wiki/Isotonic_regression). Pool adjacent violators was introduced by M. Ayer et al. in 1955. A history and development of isotonic regression algorithms is in [Leeuw, Hornik, Mair, Isotone Optimization in R: Pool-Adjacent-Violators Algorithm (PAVA) and Active Set Methods](http://www.jstatsoft.org/v32/i05/paper) and list of available algorithms including their complexity is listed in [Stout, Fastest Isotonic Regression Algorithms](http://web.eecs.umich.edu/~qstout/IsoRegAlg_140812.pdf). An approach to parallelize the computation of PAV was presented in [Kearsley, Tapia, Trosset, An Approach to Parallelizing Isotonic Regression](http://softlib.rice.edu/pub/CRPC-TRs/reports/CRPC-TR96640.pdf). The implemented Pool adjacent violators algorithm is based on [Floudas, Pardalos, Encyclopedia of Optimization](http://books.google.co.uk/books?id=gtoTkL7heS0C&pg=RA2-PA87&lpg=RA2-PA87&dq=pooled+adjacent+violators+code&source=bl&ots=ZzQbZXVJnn&sig=reH_hBV6yIb9BeZNTF9092vD8PY&hl=en&sa=X&ei=WmF2VLiOIZLO7Qa-t4Bo&ved=0CD8Q6AEwBA#v=onepage&q&f=false) (Chapter Isotonic regression problems, p. 86) and [Leeuw, Hornik, Mair, Isotone Optimization in R: Pool-Adjacent-Violators Algorithm (PAVA) and Active Set Methods](http://www.jstatsoft.org/v32/i05/paper), also nicely formulated in [Tibshirani, Hoefling, Tibshirani, Nearly-Isotonic Regression](http://www.stat.cmu.edu/~ryantibs/papers/neariso.pdf). Implementation itself inspired by R implementations [Klaus, Strimmer, 2008, fdrtool: Estimation of (Local) False Discovery Rates and Higher Criticism](http://cran.r-project.org/web/packages/fdrtool/index.html) and [R Development Core Team, stats, 2009](https://github.com/lgautier/R-3-0-branch-alt/blob/master/src/library/stats/R/isoreg.R). I ran tests with both these libraries and confirmed they yield the same results. More R implementations referenced in aforementioned [Leeuw, Hornik, Mair, Isotone Optimization in R: Pool-Adjacent-Violators Algorithm (PAVA) and Active Set Methods](http://www.jstatsoft.org/v32/i05/paper).

…pattern mining in MLlib Apriori is the classic algorithm for frequent item set mining in a transactional data set. It will be useful if Apriori algorithm is added to MLLib in Spark. This PR add an implementation for it. There is a point I am not sure wether it is most efficient. In order to filter out the eligible frequent item set, currently I am using a cartesian operation on two RDDs to calculate the degree of support of each item set, not sure wether it is better to use broadcast variable to achieve the same.

This pull requests integrates SparkR, an R frontend for Spark. The SparkR package contains both RDD and DataFrame APIs in R and is integrated with Spark's submission scripts to work on different cluster managers. Some integration points that would be great to get feedback on: 1. Build procedure: SparkR requires R to be installed on the machine to be built. Right now we have a new Maven profile `-PsparkR` that can be used to enable SparkR builds 2. YARN cluster mode: The R package that is built needs to be present on the driver and all the worker nodes during execution. The R package location is currently set using SPARK_HOME, but this might not work on YARN cluster mode. The SparkR package represents the work of many contributors and attached below is a list of people along with areas they worked on edwardt (edwart) - Documentation improvements Felix Cheung (felixcheung) - Documentation improvements Hossein Falaki (falaki) - Documentation improvements Chris Freeman (cafreeman) - DataFrame API, Programming Guide Todd Gao (7c00) - R worker Internals Ryan Hafen (hafen) - SparkR Internals Qian Huang (hqzizania) - RDD API Hao Lin (hlin09) - RDD API, Closure cleaner Evert Lammerts (evertlammerts) - DataFrame API Davies Liu (davies) - DataFrame API, R worker internals, Merging with Spark Yi Lu (lythesia) - RDD API, Worker internals Matt Massie (massie) - Jenkins build Harihar Nahak (hnahak87) - SparkR examples Oscar Olmedo (oscaroboto) - Spark configuration Antonio Piccolboni (piccolbo) - SparkR examples, Namespace bug fixes Dan Putler (dputler) - Dataframe API, SparkR Install Guide Ashutosh Raina (ashutoshraina) - Build improvements Josh Rosen (joshrosen) - Travis CI build Sun Rui (sun-rui)- RDD API, JVM Backend, Shuffle improvements Shivaram Venkataraman (shivaram) - RDD API, JVM Backend, Worker Internals Zongheng Yang (concretevitamin) - RDD API, Pipelined RDDs, Examples and EC2 guide Author: Shivaram Venkataraman <shivaram@cs.berkeley.edu> Author: Shivaram Venkataraman <shivaram.venkataraman@gmail.com> Author: Zongheng Yang <zongheng.y@gmail.com> Author: cafreeman <cfreeman@alteryx.com> Author: Shivaram Venkataraman <shivaram@eecs.berkeley.edu> Author: Davies Liu <davies@databricks.com> Author: Davies Liu <davies.liu@gmail.com> Author: hlin09 <hlin09pu@gmail.com> Author: Sun Rui <rui.sun@intel.com> Author: lythesia <iranaikimi@gmail.com> Author: oscaroboto <oscarjr@gmail.com> Author: Antonio Piccolboni <antonio@piccolboni.info> Author: root <edward> Author: edwardt <edwardt.tril@gmail.com> Author: hqzizania <qian.huang@intel.com> Author: dputler <dan.putler@gmail.com> Author: Todd Gao <todd.gao.2013@gmail.com> Author: Chris Freeman <cfreeman@alteryx.com> Author: Felix Cheung <fcheung@AVVOMAC-119.local> Author: Hossein <hossein@databricks.com> Author: Evert Lammerts <evert@apache.org> Author: Felix Cheung <fcheung@avvomac-119.t-mobile.com> Author: felixcheung <felixcheung_m@hotmail.com> Author: Ryan Hafen <rhafen@gmail.com> Author: Ashutosh Raina <ashutoshraina@users.noreply.github.com> Author: Oscar Olmedo <oscarjr@gmail.com> Author: Josh Rosen <rosenville@gmail.com> Author: Yi Lu <iranaikimi@gmail.com> Author: Harihar Nahak <hnahak87@users.noreply.github.com> Closes #5096 from shivaram/R and squashes the following commits: da64742 [Davies Liu] fix Date serialization 59266d1 [Davies Liu] check exclusive of primary-py-file and primary-r-file 55808e4 [Davies Liu] fix tests 5581c75 [Davies Liu] update author of SparkR f731b48 [Shivaram Venkataraman] Only run SparkR tests if R is installed 64eda24 [Shivaram Venkataraman] Merge branch 'R' of https://github.com/amplab-extras/spark into R d7c3f22 [Shivaram Venkataraman] Address code review comments Changes include 1.

When the workspace is saved (from R or RStudio) the backend connection seems to be closed before the finalizer is run. In such cases we reopen the connection and stop the backend 2. With RStudio when R is restarted, there are port-conflicts which appear due to a race condition between the JVM and rsession restart. This change adds a 1 sec sleep to avoid this race. 12c102a [Zongheng Yang] Simplify a unit test. 9c0637a [Zongheng Yang] Merge pull request #137 from shivaram/fix-docs 0df0e18 [Shivaram Venkataraman] Fix documentation for includePackage 7549f88 [Zongheng Yang] Merge pull request #136 from shivaram/man-updates 7edbe46 [Shivaram Venkataraman] Add missing man pages 9cb9567 [Shivaram Venkataraman] Merge pull request #131 from shivaram/rJavaExpt 1fa722e [Shivaram Venkataraman] Rename to SerDe now 2fcb051 [Shivaram Venkataraman] Rename to SerDeJVMR d112cf0 [Shivaram Venkataraman] Style fixes 9fd01cc [Shivaram Venkataraman] Remove unnecessary braces 0881931 [Shivaram Venkataraman] Some more style fixes f00b531 [Shivaram Venkataraman] Address code review comments.

…ontext This PR follow up PR apache#3907 & apache#3891 & apache#4356. According to marmbrus liancheng 's comments, I try to use fs.globStatus to retrieve all FileStatus objects under path(s), and then do the filtering locally. [1]. get pathPattern by path, and put it into pathPatternSet. (hdfs://cluster/user/demo/2016/08/12 -> hdfs://cluster/user/demo/*/*/*) [2]. retrieve all FileStatus objects ,and cache them by undating existPathSet. [3]. do the filtering locally [4]. if we have new pathPattern,do 1,2 step again.

JIRA: https://issues.apache.org/jira/browse/SPARK-5563 The PR contains the implementation for [Online LDA] (https://www.cs.princeton.edu/~blei/papers/HoffmanBleiBach2010b.pdf) based on the research of Matt Hoffman and David M. Blei, which provides an efficient option for LDA users. Major advantages for the algorithm are the stream compatibility and economic time/memory consumption due to the corpus split.

… to ShuffleReader This commit updates the shuffle read path to enable ShuffleReader implementations more control over the deserialization process. The BlockStoreShuffleFetcher.fetch() method has been renamed to BlockStoreShuffleFetcher.fetchBlockStreams(). Previously, this method returned a record iterator; now, it returns an iterator of (BlockId, InputStream). Deserialization of records is now handled in the ShuffleReader.read() method. This change creates a cleaner separation of concerns and allows implementations of ShuffleReader more flexibility in how records are retrieved.
