Inferring High-Dimensional Dynamic Networks Changing with Multiple Covariates
Louis Dijkstra, Arne Godt, Ronja Foraita
High-dimensional networks play a key role in understanding complex relationships. These relationships are often dynamic in nature and can change with multiple external factors (e.g…
An Alternating Direction Method of Multipliers Algorithm for the Weighted Fused LASSO Signal Approximator
Louis Dijkstra, Moritz Hanke, Niklas Koenen +1
We present an Alternating Direction Method of Multipliers (ADMM) algorithm designed to solve the Weighted Generalized Fused LASSO Signal Approximator (wFLSA). First, we show that w…
Improving Finite Sample Performance of Causal Discovery by Exploiting Temporal Structure
Christine W Bang, Janine Witte, Ronja Foraita +1
Methods of causal discovery aim to identify causal structures in a data driven way. Existing algorithms are known to be unstable and sensitive to statistical errors, and are theref…
An Exposure Model Framework for Signal Detection based on Electronic Healthcare Data
Louis Dijkstra, Tania Schink, Ronja Foraita
Despite extensive safety assessments of drugs prior to their introduction to the market, certain adverse drug reactions (ADRs) remain undetected. The primary objective of pharmacov…
