KernelSHAP-IQ: Weighted Least-Square Optimization for Shapley Interactions

no code implementations17 May 2024 Fabian Fumagalli, Maximilian Muschalik, Patrick Kolpaczki, Eyke Hüllermeier, Barbara Hammer

As a result, we propose KernelSHAP-IQ, a direct extension of KernelSHAP for SII, and demonstrate state-of-the-art performance for feature interactions.

Approximating the Shapley Value without Marginal Contributions

no code implementations1 Feb 2023 Patrick Kolpaczki, Viktor Bengs, Maximilian Muschalik, Eyke Hüllermeier

The Shapley value, which is arguably the most popular approach for assigning a meaningful contribution value to players in a cooperative game, has recently been used intensively in explainable artificial intelligence.

Non-Stationary Dueling Bandits

no code implementations2 Feb 2022 Patrick Kolpaczki, Viktor Bengs, Eyke Hüllermeier

We propose the $\mathrm{Beat\, the\, Winner\, Reset}$ algorithm and prove a bound on its expected binary weak regret in the stationary case, which tightens the bound of current state-of-art algorithms.
