Small molecule retrieval from tandem mass spectrometry: what are we optimizing for?
Gaetan De Waele, Marek Wydmuch, Krzysztof DembczyÅski +2
One of the central challenges in the computational analysis of liquid chromatography-tandem mass spectrometry (LC-MS/MS) data is to identify the compounds underlying the output spe…

Consistent algorithms for multi-label classification with macro-at- metrics
Erik Schultheis, Wojciech KotÅowski, Marek Wydmuch +3
We consider the optimization of complex performance metrics in multi-label classification under the population utility framework. We mainly focus on metrics linearly decomposable i…

A General Online Algorithm for Optimizing Complex Performance Metrics
Wojciech KotÅowski, Marek Wydmuch, Erik Schultheis +2
We consider sequential maximization of performance metrics that are general functions of a confusion matrix of a classifier (such as precision, F-measure, or G-mean). Such metrics…
