Using weka's StringKernel with multiple string attributes

Hello,

When I load a dataset with 2 string attributes using weka's Explorer, and build a classifier using SMO/StringKernel, it seems that weka automatically merges the string attributes into one.
But when I load the same date with the java api, it only use the first attribute and ignore the other one...
Is there a way I can reproduce this behavior using the java API?

hello,

I'm trying read an excel file a the main source of information to be used by a prpt file. The excel file would be updated everyday, and I would need the report to reflect those changes. But as I observed, it does not show the changes on the excel source file. For the additional data to be shown, I'd need to reimport the spreadsheet.

Or is this type of data source really designed for static data?

Hello,

I'm using Group By to calculate some aggregates. One particular one that I'd like to create is a SUM, but instead of summing over all rows in the group, I'd like to exclude the last row, i.e. if a group has n rows, Sum(n - 1 rows). How can I do this in Group By, or is there an alternative?

Hi

We have numerous transformations that we utilise between different environments which may take data from a source where the field length in the source is larger than the target database.

I know PDI has the ability to tell me where table changes are required and provide the sql to run this.
It's very useful for telling me this information but extremely dangerous if run in our environments due to the way the overlaying software handles it's field lengths.

It seems that (not sure if other databases too) when migrating to SQL Server it is running this SQL regardless.
It used to give me an error stating that data truncation would occur.

Is this something that can be turned off or something other people have seen?
I find it difficult to believe that this is the default behaviour now, to auto extend fields where data truncation would occur.

Just to be clear, we have NOT accidentally run this SQL. In this particular environment it has never even been viewed.

Any thoughts? Is this a JIRA? Or am I doing something wrong?

Bill

Hey there, I am interested in creating a pyramid (like the first image at http://en.wikipedia.org/wiki/Population_pyramid) I assum this could be done with two bar charts with horizontal orientation. The thing I dont really understand how to do would be to turn one of the graphs to face the left, rather than the right as is the default functionality. I also would like to make sure the values on the Y axis are on the outter edges of each of the horizontal charts so that they can be back to back nice and tight. If anyone has any idea of what properties I can change to accomplish this that would be great. Thanks!

I have a very simple transformation: I read form a table and update in another, in the same database. Some fields are numeric, integer and decimal. My database is MySql. The numeric fields are defined as INT and Decimal(10,2). The first record gets numbers like 28 19 9 67.8751.

Then I get the error. I tried to change the fields defined as Int to BigInt, but I get the same error.

Where or how can I format the number I'm reading?

Hi,

I'm trying to run an update statement in execute sql script:

update ${v_table_name}
set url = regexp_replace(url ,'${regex}', E'$1$2XNAME', 'ig')
where (id between ? and ?)
and id <= ?;

I have both variable substitution and argument replacement in the same query. The problem is:

the argument is coming from a get rows from result from a previous transformation's copy rows to result. For the argument to work I've to check Execute for each row check box, but if I do that, the variable substitution doesn't work and viceversa. Not sure how to handle this.

Any help appreciated.

Thanks,
Manasa

I am trying to use kettle 4.4.0 to read a column family from a Cassandra cluster andI am getting a weird error:

the Column family [COLFAMILY-NAME] does not seem to exist in the keyspace [KEYSPACE-NAME]

I have verified that it does using CQLSH. the one thing I noticed is that we create our keyspaces and column families using CQL 3.0.0 would this be causing this error? If it is the issue is there a workaround?

So I have a data cube set up and connected my dashboard to it. I have set up a chart that looks at some information across all waves of the study (there are 4 waves). I would like the default functionality to be showing the information for all 4 waves, with the ability to filter based on a specific wave. I have set up a select component using a SQL query (with a union) to create the possible selections of All (default), Wave 1, Wave 2, Wave 3, Wave 4. I am passing this to an MDX query. My query selects all waves by using the [Variable].[Value].Members, but for individual waves it looks like this [Variable].[Wave 1].

I want to know if there is a way to specify different values to pass based on the select components. I would essentially like to have my query look like this
[Variable].${wave}

where
All -> [Value].Members
Wave 1 -> [Wave 1]
Wave 2 -> [Wave 2]
Wave 3 -> [Wave 3]
Wave 4 -> [Wave 4]

Does anyone know how I can pass these specific values based on the appropriate selection?

Hello - I'm not new to BI at all, but I am new to using PRD 3.9 CE. I created a simple list report, with one grouping using Excel 2010 as my data source. That worked fine. To refresh with new data, I go to the Data tab > [Query Name] > Edit Query > Import Spreadsheet > click OK. That works fine. However, when I go to [Query Name] > Select Query, one of the data types changes from "Double" to "Object". This seems to be causing weird formatting problems in the report now. Is this normal behavior?

Other than the raw data, nothing changed in the spreadsheet. There is no special formatting in the spreadsheet.

Is there a way to manually edit the data types?

Thanks.

Hello !

Let's say we have the following cube : Cube (Date_id*, Address_id*, Patient_id*, Treatment_id*, ConsultationNumber).
During a specific date, a patient could have only one address, but could have zero or many treatments !

Exemple :

March 2013 | Place 1 | Patient 1 | Treatment 1 || 1 Consultation
March 2013 | Place 1 | Patient 1 | Treatment 2 || 1 Consultation

As you can see, the patient has many treatments, but it's during a specific date (one consultation), so when grouping the treatment's column, i want the measure calculation to be correct, 1 in this case, and not the sum of the child's measures (which gives 2 in this case) !

March 2013 | Place 1 | Patient 1 | All treatments || 1 Consultation

If you have any idea how i can do this, please let me know !

Thank you.

First, sorry for my english,

Hi, i'm developing a text classifier for adverts. I have never used weka before but i have tried with it and i am having few problems.

I am going to explain my issues to see if somebody kindly can help me with it.

I have classified 100.000 adverts in a dataset. (field 1 -> advert text, field 2 -> category). Then i do this:

Apply filter NominalToString to field 1.

Apply filter StringToWordVector to field 1 with stopwords and stemmer.

I remove the attributes that are not useful.

I apply/train with NaiveBayesMultinomialUpdateable algorithm and dataset but when do this, i have an error of memory heap size (with -Xmx (8gb)) and not finish.

Would anybody provide me any suggestion, documentation, links...

Thanks in advance.

WEKA job keeps running after model saved (job finished)

Hi

I run weka jobs from command line or batch files on ubuntu.


Even after the job's saved the learned model it keeps on using CPU and memory as if it was still working, this can take even hours before it closes. (the process still has its PID and the resources consumed are the same as before the model was built)

I also use -v -o params to suppress any other output.This is happening regardless what model I train or regardless complexity of model and filter nesting used.

Whats the problem? Or is there a way to force it to stop after model is serialized/ stored (using -d)?

I am using:

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

Weka 3.6.1



thx

Is there any way to permanently set the value of ${Internal.Transformation.Filename.Directory}?

It's a bit tiresome to have to repeatedly re-enter it into the variable definitions at launch.

In production it's no problem I can set it in the invoking script.

I'm still using 4.3.0... Is this fixed in future releases?
