Hi
Everyone,I want to read my persian data with Clementine 11.1

Source Node ,and connect to My Sql with ODBC , it can't read data with type

Clementine 12. client version TLA node error
-
Hello
Has anyone experienced TLA execution failures with large files?
Error:
Error: Text Link Analysis Error: Exception: SessionManager: Cannot remove temporary directory - Memory : 628899kb - Memory peak : 663449kb
Error: Text Link Analysis Execution Error
Information: Stream execution complete, Elapsed=1315.48 sec, CPU=1313.19 sec
Warning: Execution was interrupted
What I am seeing are massive "matching text" cells within records.
Anyone know how to prevent this, or better yet, fix it.
Support punted to development, then crickets...
Thanks

Migrating to WEKA...
-
Hello, I may have to migrate from Clementine to WEKA one of this days. Has anyone had experience with this program? I'm downloading it now and I will start testing it, but I have no idea.
Any comments/opinions/suggestions will be very useful, thank you.
A.
PD: I don't intend to open Clementine streams in WEKA ("migrate" can be misinterpreted), I intend to do the same things I am doing with Clementine, but in WEKA.

balance node pushback as SQL (stratified sampling)
-
You are probably familiar with the Balance node. It performs the function of selectively and randomly sampling your data based upon the values of a field or number of fields. Also known as stratified sampling!
If your data is managed by a data warehouse, then Clementine has this cool behaviour of automatically converting functions into SQL, so the data processing can be performed by the database and less data needs to be extracted and duplicated on another file system.
Unfortunately the Balance node isn't one of the functions automatically converted into SQL. In order to perform stratified sampling you have to take a different approach and selectively pick the values of your target column/field and sample them individually.
I attached one Clementine version 12.0.2 stream (balance node.zip, rename to .str) as one example of how to do this. By using a select condition, followed by a random sample, followed by a union (append) it is possible to easily obtain a stratified sample from a huge dataset efficiently.
I have also pasted below an example of the type of simple SQL that gets processed;
SELECT *
FROM (
SELECT *
FROM (
SELECT *
FROM IPSHARE.TMANNS_DRUG4n
WHERE (Drug = 'drugA')
SAMPLE 0.5
) AS TimTemp1
UNION ALL
SELECT *
FROM (
SELECT *
FROM IPSHARE.TMANNS_DRUG4n
WHERE (Drug = 'drugX')
SAMPLE 0.2
) AS TimTemp2
) AS TimTable
;

Script matrix node
-
Hi,
Is it possible to script in an unique export in .csv file from each set or ordered set' fields crossed by a field name "target" (set filed) with matrix node ? If it's not possible, may be exported in differents .csv ?
Could you give me an example ? or the solution ;-)
Thank you very much

Using scripting in Bath mode, how to ignore the error interruption until all actions are completed
-
Hi,
When running a stream than contains node CHAID and Logistic in Batch mode, because no model was created for CHAID, the execution was interrupted so as to fail to run all actions .
======== Clem_batch log file shows as follows: ==========
Information: Stream execution started
E3138: Stopping rules prevent any tree growth
Error: Model building completed but no model was created
Information: Stream execution complete, Elapsed=16.55 sec, CPU=14.14 sec
Warning: Execution was interrupted
Error: Script execution was interrupted on line 59 column 3
Failed to run all actions, error code: 1
==========================================================
My question is:
Using scripting in Bath mode, how to ignore the error interruption and automatically skip to the next node. let the running no stop until all actions are completed? and how to get its error code by scripting? (By the way, my data have no any problem, no null and no blank, are full complete data set.)
Thanks a lot!!

I started a blog...

fyi
I'll try to write about Clementine and data mining related activities in my Blog, but other stuff will be in there too.
The blog is just my ramblings. Not a replacement for my input to this forum!
