Wiki for On-Line Prediction

This website is a wiki for research in On-line Prediction (mainly Conformal Prediction). It provides two resources:

  • Overviews of various research topics.
  • Descriptions of open questions.

There are both articles about theory and articles about experimental results (we try to separate theory and experiments, covering them in different, often cross-referenced, articles). As usual for wikis, you should not trust formal statements and formulas as much as you would for published books and papers; the main role of this wiki is to provide references, to serve as a forum for informal discussions (even speculations) and stating open questions. The full list of open questions on this site can be obtained by clicking "Open Questions" on the SideBar (to the left of this text), but more useful lists are given under various research areas (such as the "Some Topics" on the SideBar).

The wiki is hosted by a server in the Department of Computer Science at Royal Holloway, University of London. But it is not moderated. Anyone may edit pages and add new pages. If you work in the area of on-line prediction, please consider participating. Even if you do not participate, please feel free to add your name to the list of People in group "Profiles".

If equations do not display properly in your browser, please follow the instructions at Latex Support to correct this.

To edit a page, click the "Edit" button at the top of the page. An author name is required; if you use your surname, the history for the page will link the change to your personal page in the wiki. You may use latex; for example, type $(x_i,y_i)$ to produce $(x_i,y_i)$. See the sidebar on the left for further editing instructions. Whenever possible, please refer to openly accessible technical reports (e.g., arXiv reports) rather than journal papers (arXiv reports often contain information about journals in which they have been published).

Update 2026: Yuri Kalnishkan has applied some fixes. At the moment editing is only possible from Royal Holloway addresses. (This is due to some issues caused by apache security, PHP, and MathJax working together.) Please contact Yuri for the password.

In LaTeX, both $...$ and \[...\] should work. Complex formatting such as aligned works. However, double slash \\ does not work; use \cr instead.
