Where does the DMS perform data preparation phase?

Hello,i'm a beginner in ODM.We know oracle data mining is embedded in oracle database,but can you tell me how the data is prepared for data mining?Thank you in advance:)

In 10.1, it depends on what API you use.
The Java api uses models that will do alot of internal data preparation if you wish.
The PL/SQL api requires the user to do their own data preparation.
The PL/SQL api provides these transformations as separate apis.
The types of data preparation required would be binning, normalization, outlier removal, missing values.
This varies on a algorithm by algorithm basis.
Please refer to the ODM documentation for more details.
Thanks, Mark

  • In sqlplus after a bad compile where does the show errors data exist?

    I am creating an automated deploy of code for project releases. In sqlplus I use the whenever command for sql errors but it doesn't catch bad compiles. When the process runs it runs as a dba user having the stored procs fully qualified causing the compile error not show in the user_errors but in all_errors. While experimenting I saw that another user could get a new record put into all_errors but my session when in sqlplus I still see the error from my compile from SHOW ERRORS. My question is where is the data from the show errors in my session stored and is it available for me to query so I can check for compile errors within sqlplus?
    Hope that was clear .
    Thanks,
    Ken

    In sqlplus ...You are in the wrong forum. This is for Oracle Forms.

  • Where does the movie that iMovie prepares go?

    I wait for an hour while imovie prepares the movie for iDVD. All seems fine. But then I run out of time and iDVD gets closed. I assume that the prepared movie is there somewhere, but next morning I cannot find it.
    Does it get erased if iDVD is closed? Does that mean I have to allocate the time both for imovie preparation of the movie and for work with iDVD? Otherwise I'll lose it??

    1) Is there a way to get my I-movie 11 project over to Final Cut? I tried to find I-movie 6 but apparently, it is no longer on the site for download. I have final cut but it won't import the project. Or will it?
    1a. No not as an editable project with transitions, texts and so on in a still editable way - BUT
    • You can Export out raw material to be used in FinalCut - and -
    • You can Export out as full quality QuickTime movie and use this in FinalCut as template and re-build project ontop of this
    1b. iMovie HD6 has never been free to be downloaded - has to be bought and now as second handed - try e-bay
    2)The quality is pretty bad when I go to I-DVD. Is there a suggestion for a better video editing program? I hear Final Cut is on the way out cause it's too complex. Premier? Vegas?
    2a. This has several layers depending on
    • What material is used
    • DVD is as standard only SD-video (No HD-DVD)
    • DVDs are interlaced and then video-editor should export this
    iMovie'08 to 11 don't handle interlaced video
    iMovie HD6 and FinalCut does -- and deliver full quality over to iDVD.
    2b. FinalCut has gone trough same disaster as did iMovie so the new version is no evolution from FinalCut Pro 1 to 7 or Express 1 to 4. It's wrongly named and iMovie X Pro might be more close to the truth.
    If You are home in iMovie'08 to 11 - I guess that FinalCut Pro X will be familiar to You and might work very well.
    Premier? Vegas? - Out of my range Error - no knowhow at all

  • Apple maps has received a poor performance rating just after introduction of the iPhone 5. I am running google maps app on the phone. Siri cannot seem to get me to a specific address. Where does the problem lie? Thanks.

    Apple maps has received a poor performance rating just after introduction of the iPhone 5. I am running Google Maps app on the phone. SIRI cannot seem to get me to a specific address. Where does the problem lie? Also can anyone tell me the hierarchy of use between the Apple Maps, SIRI, and Google maps when the app is on the phone? How do you choose one over the other as the default map usage? Or better still how do you suppress SIRI from using the Apple maps app when requesting a "go to"?
    I have placed an address location into the CONTACTS list and when I ask SIRI to "take me there" it found a TOTALLY different location in the metro area with the same street name. I have included the address, the quadrant, (NE) and the ZIP code into the CONTACTS list. As it turns out, no amount of canceling the trip or relocating the address in the CONTACTS list line would prevent SIRI from taking me to this bogus location. FINALLY I typed in Northeast for NE in the CONTACTS list (NE being the accepted method of defining the USPS location quadrant) , canceled the current map route and it finally found the correct address. This problem would normally not demand such a response from me to have it fixed but the address is one of a hospital in the center of town and this hospital HAS a branch location in a similar part of town (NOT the original address SIRI was trying to take me to). This screw up could be dangerous if not catastrophic to someone who was looking for a hospital location fast and did not know of these two similar locations. After all the whole POINT of directions is not just whimsical pasttime or convenience. In a pinch people need to rely on this function. OR, are my expectations set too high? 
    How does the iPhone select between one app or the other (Apple Maps or Gppgle Maps) as it relates to SIRI finding and showing a map route?  
    Why does SIRI return an address that is NOT the correct address nor is the returned location in the requested ZIP code?
    Is there a known bug in the CONTACTS list that demands the USPS quadrant ID be spelled out, as opposed to abreviated, to permit SIRI to do its routing?
    Thanks for any clarification on these matters.

    siri will only use apple maps, this cannot be changed. you could try google voice in the google app.

  • I installed a game, where can i find the files and maps? where does iMac store this data?

    I installed a game,Now I need to add some files however, I cannot find where iMac stores it.. where can i find the files and maps? where does iMac store this data?
    thx alot
    erik

    Depends on game, i would look first on the game file itself, right click (or ctrl click) the game file you installed (Applications?) and select show package contents, its usually a application bundle, as in basicly a folder where the application and the required files and subfolders are.

  • Where does the data get saved from (notepad) or Notes on Windows Mobile 5?

    Where does the data get saved from (notepad) or Notes on Windows Mobile 5?
    (ON the Phone)  Sticky note like program WM5
    I ask because I synced my Blackjack 1 to my pc after about a year and MANY notes later, All the notes from the PC remained but ALL new notes on phone (a years worth) were deleted from the phone.
    I would like to attempt a data recovery on my mobile device- that was an insane endeavor but i got it to work now i just need to know what to look for (what type of files to recover) and or where to recover from?
    I did make the phone a drive already and have data recovery software that can pull deleted files from the phone in fat or raw data format.
    Thanks.

  • Where does the data come from which powers the ship date and delivery date

    Hi All,
    Please let me know, where does the data come from which powers the ship date and delivery date?.
    Adi.

    Hi,
    DELIVERY DATE  will be maintain in the SALES DOCUMENT TYPES in VOV8 in the tab REQUESTED DELIVERY DATE/PRICING DAE/PURCHASE ORDER DATE.
    The field is PROPOSE DELIVERY DATE .
    If you check the field then the document created date will be the Requested date and will be carried from ORDER TO DELIVERY.
    If you want the delivery date other thann the CURRENT date then you have to maintain the LEAD TIME in days in the same tab.
    SHIP DATE: is the date on which you do the PGI in the delivery .
    Please check them and revert back if u need further details
    thanks,

  • Where does the Bill of substance maintained in property tree?

    Dear Experts,
    Where does the Bill of substance maintained in property tree? My understanding is it shows in section 2 in MSDS under composition tab. Please correct or confirm my understanding.
    Devdatt

    Dear Devdatt
    there are by standard two options available. Both have their pros and cons:
    a.) Standard EHS Export => a process which is not user friendly and without specific access rights can not be used
    b.) There are two other output variant available which you could check if they fulfill the needs of the users etc.:
    Check e.g. Displaying Properties - Basic Data and Tools (EHS-BD) - SAP Library
    as well as:
    Displaying Specification Data - Basic Data and Tools (EHS-BD) - SAP Library
    Regarding the first one: you can only download at max 50 properties in one run; regarding the second one: I am using this rarely but it is the most flexible one; not sure if the DG properties are supported. In any case: try it.
    If neither a.) nor b.) are the right solution: just create your onw ABAP code and prepare a suitable output variant on your own. You can use the "full blown SAP scenario" here (a.g. ALV like output variants etc.) ; you need to "only" learn from ABApcode of the standard output variant so that you are able to create your own one. This approach is quite standard and used very often
    Keep in mind. if you use STANDARD property tree and you have a lot of properties/data to be read performance is in most cases "bad"

  • Random Vectors/images color inverted in print, but not in PDF. Where does the fault lie?

    Sent a PDF to the newspaper printer and some of the images had inverted/strange colors. However...
    In one case I had duplicate images of a pink vector flower. SOME of the flowers were inverted, to a dark blue/black, and some were fine(pink). These were embedded vectors.
    In other instances vectors, went from orange to blue/black, pink to blue/black, and yellow/white to blue black. I specify because in one vector image, a ring, the ring was yellow, but the diamond was white, and it all changed to the same blue/black in print.
    Finally, there were two greyscale Tiff photographs of a pair of ladies. These are not embedded, and have not been altered at all and since the last time this paper has been printed, (which printed fine). This time, they were inverted. Nothing else on the page was inverted.
    As far as I can tell, there is not a separation issue, and I have saved the file from InDesign CC to pdf using the same settings as dozens of times before. The pdf on my end looks fine. The printer says they just print what they receive, but as far as I can tell, there is no issue on our end. The fact that some duplicated images printed fine, and others did not seem to confirm this. Everything is properly linked. Has anyone else experienced this problem? Is this a pdf, InDesign, or even an adobe problem at all, or it is something on their end? I have heard of inverted colors before, but can't find a solution (especially as I can't even see the problem on my end.)
    Using Windows 8, up-to-date InDesign CC, and Acrobat Pro, Illustrator CS6 ver.16.2.0 64bit
    I have no idea what the printer uses.

    Where does the fault lie? - in an environment where they (the newsprinter) collect up front, have no responsibility for quality and arrogantly believe, perhaps correctly, that you'll be back with another paying job in the future.
    Check the file you sent via Acrobat Preflight or Output Preview for RGB elements.
    Check the file you sent via Acrobat Preflight - Checks - For Transparency Used
    Do any of these elements off color involve rgb or interact (with or near) any transparency?
    (InDesign could show these attributes via the links panel or a Live Preflight. Both can be (probably should be in your case) changed via the PDF Export)

    Where does the information get stored when you sync/back up your i-phone. I have no idea where to look if I need it again!
    Thanks

    You can chhose the backup when you would reset your device. In this case you would get the option, during the set up process, to choose your backup and restore your device from it.
    (You can find a few information e.g. size and date of your backup in "Settings > iCloud > Storage & Backup > Manage Storage")

  • Where does the logging in RDBMSRealm go  --and-- are some JavaDocs missing?

    I see that a LogOutputStream is created in the example
    class RDBMSRealm, but where do all of the log
    statements go. The LogOutputStream is created as:
    log = new LogOutputStream("RDBMSRealm");
    but I do not see and file called RDBMSRealm and/or
    I do not see the log statements on stdout.
    BTW, I do have logging set to the most detailed
    level (Info) from the console if this matters.
    Also, are there some JavaDocs missing from
    Weblogic's Reference website at
    http://edocs.bea.com/wls/docs60/javadocs/index.html
    LogOutputStream is an example. I do not see the
    class when I select the package
    weblogic.logging.
    Where is it?
    Much Thanks
    Bill Ralenkotter.

    Thanks Terry,
    Sorry, I should have mentioned that I am using WL6.0.
    Does anyone know what I need to do to get the RDBMS Realm log to start on
    WL6.0.
    About the missing JavaDocs: Also, if I am doing development using these
    classes I still do not
    understand why they are not on the 6.0 refernce site!
    About the missing JavaDocs,
    I see java docs for a lot of classes, but what document do I use that
    helps me to understand the entire framework? The Programming
    Weblogic Security does give this information.
    Example question: how do I get a reference to the realm to create
    users? Should I even be doing this?
    Thanks for your help.

    If you are using WLS5.1 you much set the property
    weblogic.security.realm.debug=true
    then this information will be sent to stdout. This is set to false by
    default, as there is a lot of information, and it is a big performance
    hit.
    I think weblogic likes to avoid some of its APIs being public, which is
    annoying at times, but probably reasonable
