Bad local minima exist in the stochastic block model
Amin Coja-Oghlan, Lena Krieg, Johannes Christian Lawnik +1
We study the disassortative stochastic block model with three communities, a well-studied model of graph partitioning and Bayesian inference for which detailed predictions based on…
A Notion of Feature Importance by Decorrelation and Detection of Trends by Random Forest Regression
Yannick Gerstorfer, Lena Krieg, Max Hahn-Klimroth
In many studies, we want to determine the influence of certain features on a dependent variable. More specifically, we are interested in the strength of the influence -- i.e., is t…
The -XORSAT threshold revisited
Amin Coja-Oghlan, Mihyun Kang, Lena Krieg +1
We provide a simplified proof of the random -XORSAT satisfiability threshold theorem. As an extension we also determine the full rank threshold for sparse random matrices over f…
