I have already adressed that problem and I made a DB-SCAN algorithm that 
run atop the xml results in order to find bigger clusters as i may have 
as input more than 200 files but still the parameters that i should give 
to both SOM and DB-SCAN is a problem. I think we can solve it with 
genetic programming.
After i migrated to Java 1.5 the results would be really bad. I would 
have only one cluster but it seems that JSOM 1.2 will address the problem.

Anyway i should say a big thanks to you for your great work.
You can see a sample of our work at http://195.251.235.67:8080/thesus

But the clustring and quering modules are not working for the moment

[Javasom-developer] JSom in servlet

[Tomi S. <tom...@mb...>]

Hi

I am so sorry for not noticing your message, but until now. :(

The follow error results exactly in the missing (actually not found)
instructions.dtd file. In the new 1.2 package there is an instructions.xml
file. which contains an embbedded version of the dtd inside that file so it
would not be a problem anymore as javasom verifies the xml to conform dtd.

[Javasom-developer] Servlet & JavaSOM

[Panayiotis P. <pa...@fr...>]

Hi everyone,
I am working on a project called thesus at DB-NET lab [ 
http://www.db-net.aueb.gr ] and i am looking forward to deploy JavaSOM 
inside a servlet.
I have done everything and everything compiles well but JavaSOM does not 
give my any results. I suspect the problem is the lack of 
instructions.dtd somewhere in exeecution environment. I guess it wont 
work if i copy it inside the classes of the algorithm and i think the 
default execution paht of Tomcat is C:\windows\ or smth like that.

Has anyone encountered any similar problems. By a quick inspection of 
the code i found nowhere the reading of instructions.dtd so i guess some 
of the jars needed. It is for sure needed i think cos when i removed it 
from the directory where the JavaSOM example was then the latter did not 
work.

Thanks in advance

[Javasom-developer] XML Issues

[Stuart M. C. <s.m...@du...>]

I have just been running the examples provided with the download and
loaded the instructions XML into XMLSpy which identified a couple of
issues

#1 In the instructions.dtd a spelling error in the first occurance of
neighbourhood (missing u)

#2 in the fragment below

<initialization>
		<normalization used="true"/>
		<x.dimension>14</x.dimension>
		<y.dimension>14</y.dimension>
		<lattice type="hexagonal"/>
		<neighbourhood type="linear"/>
	</initialization>


the neighbourhood type is set to linear whilst the DTD only allows
gaussian or step

Regards
Stuart
