Explaining graph neural networks via structure-aware interaction index

N Bui, HT Nguyen, VA Nguyen, R Ying - arxiv preprint arxiv:2405.14352, 2024 - arxiv.org
The Shapley value is a prominent tool for interpreting black-box machine learning models
thanks to its strong theoretical foundation. However, for models with structured inputs, such …

The Expected Shapley value on a class of probabilistic games

S Borkotokey, S Gowala, R Kumar - arxiv preprint arxiv:2308.03489, 2023 - arxiv.org
We study a class of probabilistic cooperative games which can be treated as an extension of
the classical cooperative games with transferable utilities. The coalitions have an …

[PDF][PDF] The Network Banzhaf Value for Deterministic and Variable Network Situations

In network games, each possible network formation within a specified set of players is
assigned a level of collectively generated wealth. A variable network game merges the …

[PDF][PDF] The Network Banzhaf Value

We investigate a new allocation rule for network situations, the network Banzhaf value
based on the Banzhaf value for cooperative games. We axiomatize it in three distinct ways …
