I have always had problems with defining a term without using the term itself. Unpredictable order emerging out of chaos. While technically not the same meaning, it still confuses the issue. I was looking at several resources for entries on emergence, and of course my first choice was the entry in Wikipedia. It is a rather in-depth article, and an interesting read. In my research this summer, I was working with different machine learning algorithms that were dependent on user-generated constraints. The user would group data together by some sort of vague, unformed criteria, and the program would infer the user's intentions. The results were often quite surprising, as the user might not even be aware of how they were sorting information until the computer analyzed it. Unexpected patterns would arise. Not really sure if this qualifies as emergence, but as I was sitting in class on Monday, I kept thinking of that experience and the surprise that followed.
