Chicago ’05 ended a couple of weeks ago. This was the sixth Machine Learning Summer School, and the second one that used a wiki. (The first was Berder ’04, thanks to Gunnar Raetsch.) Wikis are relatively easy to set up, greatly aid social interaction, and should be used a lot more at summer schools and workshops. They can even be used as the meeting’s webpage, as a permanent record of its participants’ collaborations — see for example the wiki/website for last year’s NVO Summer School.
A basic wiki is a collection of editable webpages, maintained by software called a wiki engine. The engine used at both Berder and Chicago was TikiWiki — it is well documented and gets you something running fast. It uses PHP and MySQL, but doesn’t require you to know either. Tikiwiki has far more features than most wikis, as it is really a full Content Management System. (My thanks to Sebastian Stark for pointing this out.) Here are the features we found most useful:
A couple of other TikiWiki features that we didn’t get working at Chicago, but would have been nice to have, are these:
- Image Galleries. Gunnar got this working at Berder, where it was a huge success. Photographs are great icebreakers, even the ones that don’t involve dancing on tables.
- Surveys. These are easy to set up, and have option for participants to see, or not to see, the results of surveys — useful when asking people to rate lectures.
TikiWiki also has several features that we didn’t use, such as blogs and RSS feeds. It also has a couple of bugs (and features that are bad enough to be called bugs), such as permission issues and the inability to print calendars neatly. These will doubtless get cleaned up in due course.
Finally, owing to much prodding from John and some other MLSS participants, I’ve written up my experiences in using TikiWiki @ Chicago ’05 on my website, including installation instructions and a list of “Good Things to Do”. This documentation is meant to be a survival guide complementary to the existing TikiWiki documentation, which can sometimes be overwhelming.
