AddAttribute file help

Hi, i'm trying to work with WEKA using jAudio that outputs audio features to a .arff file, in the tutorial here http://www.cs.cmu.edu/~music/cmsip/projects/p6.pdf it says i need to use the AddAttribute.java file to add in a genre attribute but i can't get it working. I'm pretty new to Java so not entirely sure how to change the code for my needs.

Ive saved the AddAttribute.java file in with the weka.jar and the file that holds the .arff files, i tried both changing the code to the .arff's file name and changed the file name to 'file.arff. like its done in the AddAttributes code and tried opening the .arff file but with no luck.
It does still open WEKA fine but only with the attributes in the .arff rather than adding the new one
http://weka.wikispaces.com/Adding+at...s+to+a+dataset is where it shows the code for AddAttribute any help would be greatly appreciated thanks

also the values of the attributes already present a numerical but the new class should be nomical so it can use a naive bayes classifier or to cluster i think

PDI Normalize row scenario

I have the following data set as an output form a table query




Codes Value
10010 TestName1
10020 Type1
10030 Value1
10110 TestName2
10120 Type2
10130 Value2






In the code first 3 characters mean identify a row to normalize to and the last 2 characters the values. The outcome of these 6 rows will become 2 in the form


Code Name Type Value
100 TestName1 Type1 Value1
101 TestName2 Type2 Value2


How can this be completed using standard Pentaho PDI steps?


Thanks for any help.

Histograms

I am trying to write an MDX query to generate histogram. The histogram buckets are based on a sequence and a dollar amount. In each bucket we are placing a count of how many sequences are between two dollar amounts. We are applying filters to the data so those sequences could end up in different buckets depending on the filters the application applies. We attempted to use the filter function to build the buckets but that results in Mondrian generating in clauses that are too big for the database to handle. We attempted to create UDF the fixes filter but we ended up having same problem.

If the buckets were based on time instead of dollars amounts or the sequences could be fixed to a bucket no matter what filters are applied this would work. Has anyone had any success on doing this kind of histogram with Mondrian?

I'm reading very large XML files using Get XML Data step. I would like to use the "Prune path to handle large files" option which improves performance drastically.
However, if I accept the files from previous step (by checking "XML source is defined in a field?"), spoon disables the Prune path option. Any suggestions?

PDI config questions regarding spoon and remote access

I've a remote server running ubuntu 12.04. Pentago bi-server ce 5.0.1 is installed and I can login as admin. Now for data integration: tutorials say just unzip and run the sh script spoon.sh. But I get "missing file" errors (mostly java swt). Now I'm wondering whether spoon should be on the server or my desktop. It sounds like this can't be accessed by a tomcat URL like the bi server. I thought the PDI would be a tomcat access via my browser and I would extract, transform, and Load (do my ETL) something like connecting to some databases via phpmyadmin.

Please help me out in my misunderstnading.

Thank you

Hii All,
From last few days i am getting problem with FTP server related issues, I have created 1 job for which i have to upload csv file to ftp server, so i am using upload files to ftps step in job, from last 2 months it was working properly but from few days after every few minutes it is giving me connection timeout error, if i restart the spoon or just try to connect by placing test connection option then it will start working again properly..

So how can i figure-out the problem or how can i resolve the issue?

Dimension with non hierarchic Levels/Members

Hi folks,

suppose you have a dimension like Car. Some properties of a car can be arranged hieratchical, eg:

DIM_CAR:
  • Hierarchy (default)
    • Brand
    • Series
    • Type


But how to model all the additional Properties. Maybe I have something like

  • SteeringWheel (L,R)
  • NumWheels (3,4,6,8)
  • Color
  • etc.


I can not place them in the same hierarchy as Brand, Series, Type because it makes no sense.

I can built additional hierarchies in my Car Dimension:

DIM_CAR:
  • Hierarchy (CarType)
    • Brand
    • Series
    • Type

  • Hierarchy (SteeringWheel)
    • SteeringWheel

  • Hierarchy (Color)
    • Color


But now I can not use more then one Hierarchy in a query. And maybe I want to do exactly that: Use the Brand as Filter, Select Color on and Steering Wheel on Columns and my Sales Fact on Rows.

So what would be the best way to model something like that? Dimensional Properties, which can not be placed in a single hierarchy?

Thanks and Regards

The 3 pillars for Pentaho Community Strategy

Almost one year on

It's been one year since Webdetails joined Pentaho. For me it seems much less than that! (even though if you ask the people that have to put up with me, I'm sure they'll say it feels like decades :p )

Throughout this time, we've been (re)defining a strategy for the Community - Yes, I actually have to do more work other than flying out to different countries in the world to have beers with interesting people. And it's a great sign to see that there's much more events than the ones I can attend.

Pentaho Community Strategy

The goals

Since the beginning, I have pretty much identified the goals for our community strategy. We want the community to be:
A place for developers

While our Enterprise offering is positioned as a production ready, enterprise scale solution, our open edition is aimed to gain the affection of the developer persona, one that's looking for an open source alternative that allows him to fulfill his goals.
An engagement mechanism

If we make it easier to bring those developers, consultants and general users on-board, they become potential contributors willing to help us building a richer ecosystem around Pentaho. If people spend their time making the tools better, competing between and helping each other, they won't even look at any competitor. They will work in order to increase the quantity and quality of the Pentaho world.
A QA environment

The more users we have using our software, the better it will become. People will exercise the codebase under several conditions allowing us to collect more feedback that will translate into a better and more stable product for the ones that pay our salary: our customers.
An evaluation territory

Every user is an evaluator and a potential subscriber. So the open edition has to be a quality release, the best we can possibly achieve.
An upsell mechanism

With the huge amount of installs, our open edition has a great potential as a lead generator that we need to take more advantage of.


I'm a huge fan of being open and honest. Even though we are, in our core, an open source company, we want to make as much money as the next guy! And I'm a firm believer that through open source, not only we'll get there much faster, we're also doing "the right thing". Whatever that means - but at least it feels that way to me!

The strategy: The 3 pillars

We actually have a plan to get there. Our strategy is based on 3 well identified components:

  • Model
  • Facilitator
  • Distribution

Model


The Project Maturity Classification is the central piece on a strategy that aims to use the Community as a vehicle to reach our goals faster.

The two-lane approach aims to promote innovation, clear out what is and what isn't supported and which levels of support attached to them, and clarifying to prospects / customers/ community/ etc how Pentaho leverages it's Open Source roots and how that puts us to a huge advantage compared to the rest of the competition.
Facilitator


If done correctly, the community can be a huge source of innovation.

And in order to promote that innovation, it has to be simple to build extensions to our product. The large amount of examples on PDI makes it simple for developers to develop new plugins and Sparkl, or Pentaho Application Builder aims to make it possible for consultants to develop those extensions on the BA server.
Distribution


The Marketplace is the main distribution vehicle, also acting as a major motivation for partners and other companies to create these extensions. The visibility they gain drives a lot of business opportunities.

It will also allow us to apply the early and often rule, giving users the ability to try early preview releases of our projects / plugins, acting as an extended QA team.


----------


Will it work? We'll see - If not, we'll try something else. Eventually, something will :)
