Semesterwork (6th) in Component Technologies and Distributed Systems. We developed in a team of 3 students

The main topic of the lecture component technologies was software engineering. We used the eclipse IDE and the myeclipse plugin to combine the JSF Technologie with the object rational mapping (ORM) capabilities of Hibernate. Useful was Borland´s Together for Eclipse to engineer the architecture. Instead of the sql queries in the backend serverside bytecode, we setup the Hibernate data persistence to save our object via ORM into the database. The example implementation was an online-schedule-system. We used CVS for sourcemanagement thanks to www.berlios.de.

Semesterwork (6th) in simulation technics was to implement an agent for playing the GO game using a neuronal net. We had a teamsize of 3 students.
package smartness.*

My part was to implement an object-oriented neuronal-net.
It was about a feedforward net which is activated by the logistic function and trained by the backpropagation algorithm with the batch-method. The topologie, the teaching patterns as well as the weights between the neurons are persistent in propertyfiles.

A basic experiment was learning the numbers from 0-9, a second one was learning the alphabet. It was not so easy to find a net-topology to learn with.

Our player worked well because we didn´t teach him just pattern of GO, remember even if u reduce the size of the playfield to 9×9 it is still 3 to the power of 81 posibilities, which is much more than u can teach in a lifetime. The player is rating the opponent´s move. The agent reduces the problem by tracking just a small space on the field and rotating this space. Our agent won against all other agents in a contest :)
