So I'm going to let this diff marinade for a day or so, but if you feel like you've got some thoughts (+1's? -1's? I'll even take some +epsilons if you're feeling cowardly) on it, feel free to comment on the ticket&lt;https://issues.apache.org/jira/browse/MAHOUT-1227&gt; or on the review &lt;https://reviews.apache.org/r/11359&gt; itself. I won't let the patch stick around forever though, as most every commit that hits trunk will force me to regenerate this patch again, given its breadth. </pre> Jake Mannix 2013-05-24T02:06:29 Build failed in Jenkins: mahout-nightly #1238 http://comments.gmane.org/gmane.comp.apache.mahout.devel/25037 <pre>See &lt;https://builds.apache.org/job/mahout-nightly/1238/changes&gt; Changes: [srowen] Update a few plugin and integration-related dependencies, and require Maven 3 for consistency ------------------------------------------ Started by timer Building remotely on ubuntu6 in workspace &lt;https://builds.apache.org/job/mahout-nightly/ws/&gt; Updating http://svn.apache.org/repos/asf/mahout/trunk U integration/src/main/java/org/apache/mahout/cf/taste/impl/model/hbase/HBaseDataModel.java U integration/pom.xml U pom.xml At revision 1485553 Parsing POMs Modules changed, recalculating dependency graph [trunk] $ /home/hudson/tools/java/latest1.6/bin/java -cp /home/jenkins/jenkins-slave/maven-agent.jar:/home/jenkins/jenkins-slave/classworlds.jar hudson.maven.agent.Main /home/hudson/tools/maven/apache-maven-2.2.1 /home/jenkins/jenkins-slave/slave.jar /home/jenkins/jenkins-slave/maven-interceptor.jar 37308 /home/jenkins/jenkins-slave/maven2.1-interceptor.jar &lt;===[JENKINS REMOTING CAPACITY]===channel started log4j:WARN Please initialize the log4j system properly.

I am hugely grateful that Mahout exists and that you guys keep it on the leading edge. Recently I had the job of trying to explain how to use Mahout to someone taking over my code. The questions he asked brought up a lot of issues I'd already absorbed and learned to deal with. Here are some of the rough edges that came up: It would be nice if *all* vectors supported attachment of properties. Something like the named vector but allowing arbitrary properties (there used to be a "PropertyVector" I think but it was removed from some code). This is huge actually any time you have a multi-job pipeline you have to introduce indexes and reverse indexes that can become a scaling problem. They work ok (though they are a pain to code up all the time) if they fit into memory, if not the pain becomes major. Many of these would disappear if arbitrary keys could be attached to any and all vectors. I understand that this doesn't make sense if a vector is transposed or elsewhere but there are many cases where it does. Scaling some jobs requires splitting files to get multiple mappers and in other cases files must be combined into one to even run the job. Scaling is one huge reason to use Mahout, so it seems like it should be easier and input should universally be a dir of parts *or* single file. It would be nice to have a consistent way to auto scale and consistent input and output expectations or options (maybe Pig is a good model?). Maybe it's good enough to keep these things in mind when new code is written. I understand that you guys work on Mahout gratis and it's always more fun to add new things than clean up. I've also seen committers who responded very quickly to requests. It seem a bit petty to mention these things but they would go a fair way towards polishing Mahout. Yes, I know I'm welcome to submit patches and will try to do so.</pre> Pat Ferrel 2013-05-15T18:15:09 Jenkins build is back to normal : Mahout-Quality #1996 http://comments.gmane.org/gmane.comp.apache.mahout.devel/24905 <pre>See &lt;https://builds.apache.org/job/Mahout-Quality/1996/&gt; </pre> Apache Jenkins Server 2013-05-15T00:39:39 Build failed in Jenkins: Mahout-Examples-Cluster-Reuters #305 http://comments.gmane.org/gmane.comp.apache.mahout.devel/24899 <pre>See &lt;https://builds.apache.org/job/Mahout-Examples-Cluster-Reuters/305/changes&gt; Changes: [smarthi] Mahout-1212: Incorrect classify-20newsgroups.sh file description ------------------------------------------ [...truncated 1478 lines...] INFO: Reduce input records=0 May 13, 2013 2:13:18 PM org.apache.hadoop.mapred.Counters log INFO: Reduce input groups=0 May 13, 2013 2:13:18 PM org.apache.hadoop.mapred.Counters log INFO: Combine output records=0 May 13, 2013 2:13:18 PM org.apache.hadoop.mapred.Counters log INFO: Physical memory (bytes) snapshot=0 May 13, 2013 2:13:18 PM org.apache.hadoop.mapred.Counters log INFO: Reduce output records=0 May 13, 2013 2:13:18 PM org.apache.hadoop.mapred.Counters log INFO: Virtual memory (bytes) snapshot=0 May 13, 2013 2:13:18 PM org.apache.hadoop.mapred.Counters log INFO: Map output records=0 May 13, 2013 2:13:19 PM org.apache.hadoop.mapreduce.lib.input.FileInputFormat listStatus INFO: Total input paths to process : 1 May 13, 2013 2:13:19 PM org.apache.hadoop.filecache.TrackerDistributedCacheManager downloadCacheObject INFO: Creating frequency.file-0 in /tmp/hadoop-jenkins/mapred/local/archive/6399501481973599857_-299119410_507314861/file/tmp/mahout-work-jenkins/reuters-out-seqdir-sparse-kmeans-work-487841752519760957 with rwxr-xr-x May 13, 2013 2:13:19 PM org.apache.hadoop.filecache.TrackerDistributedCacheManager downloadCacheObject INFO: Cached /tmp/mahout-work-jenkins/reuters-out-seqdir-sparse-kmeans/frequency.file-0 as /tmp/hadoop-jenkins/mapred/local/archive/6399501481973599857_-299119410_507314861/file/tmp/mahout-work-jenkins/reuters-out-seqdir-sparse-kmeans/frequency.file-0 May 13, 2013 2:13:19 PM org.apache.hadoop.filecache.TrackerDistributedCacheManager localizePublicCacheObject INFO: Cached /tmp/mahout-work-jenkins/reuters-out-seqdir-sparse-kmeans/frequency.file-0 as /tmp/hadoop-jenkins/mapred/local/archive/6399501481973599857_-299119410_507314861/file/tmp/mahout-work-jenkins/reuters-out-seqdir-sparse-kmeans/frequency.file-0 May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.JobClient monitorAndPrintJob INFO: Running job: job_local_0006 May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.Task initialize INFO: Using ResourceCalculatorPlugin : org.apache.hadoop.util.LinuxResourceCalculatorPlugin&lt; at &gt;25fe3515 May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.MapTask$MapOutputBuffer &lt;init&gt; INFO: io.sort.mb = 100 May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.MapTask$MapOutputBuffer &lt;init&gt; INFO: data buffer = 79691776/99614720 May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.MapTask$MapOutputBuffer &lt;init&gt; INFO: record buffer = 262144/327680 May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.MapTask$MapOutputBuffer flush INFO: Starting flush of map output May 13, 2013 2:13:19 PM org.apache.hadoop.mapred.Task done INFO: Task:attempt_local_0006_m_000000_0 is done.

I recently talked to one of the authors of streaming k-means, Adam Meyerson asking about the distance cutoff as I wasn't sure of a right value for this. He told me two things: - that we should multiply the distance / distanceCutoff ratio by the weight of the point we're trying to cluster so as to avoid collapsing larger clusters - the initial cutoff they use is 1 / numClusters basically As I tested the code on multiple well known data sets, this got me thinking of removing the distanceCutoff all together. It seems like just another parameter to get right with only limited real value of fiddling with it. Additionally, clusterOvershoot, the thing we're using to delay distance cutoff increases also seems somewhat unnecessary. Why use it and get a lot more centroids than what we asked for. I want to post a final version for review, but I just wanted to mention these two things. It's not like they "hurt" really, they just don't seem to be helping too much and I'd rather have something that more closely matches the theoretical guarantees in the paper. What do you think? </pre> Dan Filimon 2013-05-08T15:45:06 Jenkins build is back to normal : mahout-nightly #1223 http://comments.gmane.org/gmane.comp.apache.mahout.devel/24825 <pre>See &lt;https://builds.apache.org/job/mahout-nightly/1223/&gt; </pre> Apache Jenkins Server 2013-05-08T02:39:34 HBase backed matrices http://comments.gmane.org/gmane.comp.apache.mahout.devel/24816 <pre>Hi, For taking large matrices as input and persisting large models (like factor models), I created an HBase-backed version of Mahout matrix. It allows random access to cells and rows as well as assignment, and iteration over rows. viewRow returns a view, and lazy loads actual data if a get is actually invoked. I plan to add a VectorInputFormat on top of it, too. The code that we need to have for our algorithms is tested, but there are still parts of it that are not. I am going to speak about this at HBaseCon, and I wanted to let you know that it can be contributed after some refactoring. Is there any interest? </pre> Gokhan Capan 2013-05-07T20:08:01 Build failed in Jenkins: Mahout-Examples-Classify-20News #186 http://comments.gmane.org/gmane.comp.apache.mahout.devel/24810 <pre>See &lt;https://builds.apache.org/job/Mahout-Examples-Classify-20News/186/changes&gt;

I know writing benchmarks it tricky in Java, but still, this searcher should be way better than brute search. So, I stepped through the code and it turns out it never adjusts the hashLimit for example. This means that it effectively computes the distance between every point and the query in addition to projecting which makes it slower. I never really looked at this class thoroughly so maybe have a look at the current searcher [2] and see what is going on? Also, what was the paper that explained this method of dynamically adjusting the hash limit? You probably sent it to me but I forgot it. Thanks!
