Towards Explainable Real Estate Valuation via Evolutionary Algorithms

1 code implementation11 Oct 2021 Sebastian Angrick, Ben Bals, Niko Hastrich, Maximilian Kleissl, Jonas Schmidt, Vanja Doskoč, Maximilian Katzmann, Louise Molitor, Tobias Friedrich

Human lives are increasingly influenced by algorithms, which therefore need to meet higher standards not only in accuracy but also with respect to explainability.

Adaptive Sampling for Fast Constrained Maximization of Submodular Function

no code implementations12 Feb 2021 Francesco Quinzan, Vanja Doskoč, Andreas Göbel, Tobias Friedrich

Our algorithm is suitable to maximize a non-monotone submodular function under a $p$-system side constraint, and it achieves a $(p + O(\sqrt{p}))$-approximation for this problem, after only poly-logarithmic adaptive rounds and polynomial queries to the valuation oracle function.

Maps for Learning Indexable Classes

no code implementations15 Oct 2020 Julian Berger, Maximilian Böther, Vanja Doskoč, Jonathan Gadea Harder, Nicolas Klodt, Timo Kötzing, Winfried Lötzsch, Jannik Peters, Leon Schiller, Lars Seifert, Armin Wells, Simon Wietheger

We study learning of indexed families from positive data where a learner can freely choose a hypothesis space (with uniformly decidable membership) comprising at least the languages to be learned.

Normal Forms for (Semantically) Witness-Based Learners in Inductive Inference

no code implementations15 Oct 2020 Vanja Doskoč, Timo Kötzing

Such results are key to understanding the, yet undiscovered, mutual relation between various important learning paradigms when learning behaviourally correctly.

Mapping Monotonic Restrictions in Inductive Inference

no code implementations15 Oct 2020 Vanja Doskoč, Timo Kötzing

In particular, we show that explanatory monotone learners, although known to be strictly stronger, do (almost) preserve the pairwise relation as seen in strongly monotone learning.

Learning Languages with Decidable Hypotheses

no code implementations15 Oct 2020 Julian Berger, Maximilian Böther, Vanja Doskoč, Jonathan Gadea Harder, Nicolas Klodt, Timo Kötzing, Winfried Lötzsch, Jannik Peters, Leon Schiller, Lars Seifert, Armin Wells, Simon Wietheger

This so-called $W$-index allows for naming arbitrary computably enumerable languages, with the drawback that even the membership problem is undecidable.

timeXplain -- A Framework for Explaining the Predictions of Time Series Classifiers

1 code implementation15 Jul 2020 Felix Mujkanovic, Vanja Doskoč, Martin Schirneck, Patrick Schäfer, Tobias Friedrich

Modern time series classifiers display impressive predictive capabilities, yet their decision-making processes mostly remain black boxes to the user.
