Specialists Outperform Generalists in Ensemble Classification
Sascha Meyen, Frieder Göppert, Helen Alber +2
Consider an ensemble of individual classifiers whose accuracies are known. Upon receiving a test point, each of the classifiers outputs a predicted label and a confidence in it…
Group Decisions based on Confidence Weighted Majority Voting
Sascha Meyen, Dorothee M. B. Sigg, Ulrike von Luxburg +1
Background: It has repeatedly been reported that when making decisions under uncertainty, groups outperform individuals. In a lab setting, real groups are often replaced by simulat…
Advancing Research on Unconscious Priming: When can Scientists Claim an Indirect Task Advantage?
Sascha Meyen, Iris A. Zerweck, Catarina Amado +2
Current literature holds that many cognitive functions can be performed outside consciousness. Evidence for this view comes from unconscious priming. In a typical experiment, visua…
Unconscious lie detection as an example of a widespread fallacy in the Neurosciences
Volker H. Franz, Ulrike von Luxburg
Neuroscientists frequently use a certain statistical reasoning to establish the existence of distinct neuronal processes in the brain. We show that this reasoning is flawed and tha…
A Geometric Approach to Confidence Sets for Ratios: Fieller's Theorem, Generalizations, and Bootstrap
Ulrike von Luxburg, Volker H. Franz
We present a geometric method to determine confidence sets for the ratio E(Y)/E(X) of the means of random variables X and Y. This method reduces the problem of constructing confide…
Ratios: A short guide to confidence limits and proper use
Volker H. Franz
Researchers often calculate ratios of measured quantities. Specifying confidence limits for ratios is difficult and the appropriate methods are often unknown. Appropriate methods a…
