Stability and aggregation of ranked gene lists (2009)
Boulesteix, Anne-Laure, Slawski, Martin
Ranked gene lists are highly instable in the sense that similar measures of differential gene expression may yield very different rankings, and that a small change of the data set usually affects the...
Feature Selection Guided by Structural Information (2009)
Slawski, Martin, Zu Castell, Wolfgang, Tutz, Gerhard
In generalized linear regression problems with an abundant number of features, lasso-type regularization which imposes an l1-constraint on the regression coefficients has become a widely established...
