This is the central portal to the iCIS Publication Management System (PMS).
About a decade ago it was intended to be the only system for keeping track of publications by iCIS members. In particular, it was the dedicated system for creating new technical reports.
However, this system has been abandoned and is only kept available for retrieving old publications.

Apart from security updates in the underlying framework, it is not supported anymore.
If you have questions about it, please contact Engelbert Hubbers.

M.A.J. van Gerven, and T. Heskes. L1/Lp regularization of Differences. Technical report: ICIS-R08009, May, Radboud University Nijmegen, 2008.

In this paper, we introduce $L_1/L_p$ regularization of differences as a new regularization approach that can directly regularize models such as the naive Bayes classifier and (autoregressive) hidden Markov models. An algorithm is developed that selects values of the regularization parameter based on a derived stability condition. for the regularized naive Bayes classifier, we show that the method performs comparably to a filtering algorithm based on mutual information for eight datasets that have been selected from the UCI machine learning repository.
