Am wondering whats the use of supporting multiple output schema as shown below in the image?
I was hoping to configure two different outputs from this DROP Field transform and in the subsequent child transform be able to select specific parent output schema as input. But i don't see that option at all, could someone help me understand the need of outputschema drop down and editing capabilities in the window(refer image)?
Thank you.
I have a package with about 25 diagrams in it. I have used EA templates to make a package report that gives the name and notes for each diagram. However I want make a more specific report that can generates the report for just one diagram containing the description from each element in the diagram. Is this possible? It does not seem like diagrams have anywhere I can generate reports from.
UPDATE: I am currently trying to figure out how to do this with Document Options>Except where Query excludes Package:>Custom SQL but cannot get it. Here is my SQL statement:
SELECT t_diagram.ea_guid & t_diagram.Name AS [DesiredService-Hyperlink]
FROM t_diagram
WHERE t_diagram.Name = 'Diagram_Name'
I tried putting this in the Report's Custom SQL, that didn't work. Then I tried putting it in a fragment's Custom SQL with the following in the template itself
custom >
{DesiredService-Hyperlink}
< custom
This also did not work. I have been trying to go off of various documentation and YouTube Videos. If anyone could point me in the right direction that would be great.
Enterprise Architect document generation is based more on the model structure then on the diagrams.
The easiest approach would be to put each diagram in a different package or nested under a specific element, even if only temporary to generate the document.
I am new to WEKA and want to get the probability distribution of all instances over all classes from classify tab to a csv file for further analysis of models.
Please suggest how to go about that in WEKA GUI explorer?
I just noticed that there is a more options button in test options under the classify tab. There you can choose CSV for output predictions. If you click on CSV you can turn outputDistribution to true and name your file.Hope this helps.
If this doesn't work then its fairly easy to do this with java code.
Not completely sure what you are asking but I gather it is the output from a cross validation/% split run that you want as a csv file? If so, the best place to achieve this is in the Experimenter tab in WEKA. First, click 'New' and add your datasets in the bottom left box after clicking 'add new.' Secondly, add your algorithms in the bottom right box having clicked 'add new.' Finally, change your results destination to 'CSV file' and browse for the file location. You can configure the experiment type and number of repetitions here also. Run the experiment in the next tab and wait for completion. You will find your results in the destination csv.
I've got a question about finding the predictive value of certain attributes.
In my question it is suggested that I transform my attributes to binary classes and then apply "decision stump" to find out the predictive value of each attribute. How do I do this?
I checked out this question But that's not really what I mean.
Thanks in advance, Rope.
You can find the most predictive attributes using the methods found under the Select Attributes tab in Weka's Explorer.
Yeah, the Select Attributes tab in Weka analyzes your attributes and ranks which ones provide the most information gain. Under Attribute Evaluator, choose InfoGainAttributeEval and choose Ranker for search method. It works quite well in my experience.
Suppose Item A contains the link Item B would like to use as the source of its Droplist field. How can I achieve this? I have read the Sitecore Query documentation here and here. It appears to me that this is not achievable using Sitecore query, but I could be mistaken. Any help would be appreciated.
No this is not possible. To set the source of a droplist, you can either set the root path to an item which would make the droplist populate the sub-items or you can use Sitecore query to query for specific items based on your query. This is covered in the Data Definition Cookbook (PDF link) under 2.4.2.
