Approximation of group explainers with coalition structure using Monte Carlo sampling on the product space of coalitions and features

no code implementations17 Mar 2023 Konstandinos Kotsiopoulos, Alexey Miroshnikov, Khashayar Filom, Arjun Ravi Kannan

In our work, we focus on a wide class of linear game values, as well as coalitional values, for the marginal game based on a given ML model and predictor vector.

On marginal feature attributions of tree-based models

1 code implementation16 Feb 2023 Khashayar Filom, Alexey Miroshnikov, Konstandinos Kotsiopoulos, Arjun Ravi Kannan

We exploit the symmetry to derive an explicit formula, with improved complexity and only in terms of the internal model parameters, for marginal Shapley (and Banzhaf and Owen) values of CatBoost models.

PDE constraints on smooth hierarchical functions computed by neural networks

no code implementations18 May 2020 Khashayar Filom, Konrad Paul Kording, Roozbeh Farhoodi

Our approach is a step toward formulating an algebraic description of functional spaces associated with specific neural networks, and may provide new, useful tools for constructing neural networks.

On functions computed on trees

no code implementations4 Apr 2019 Roozbeh Farhoodi, Khashayar Filom, Ilenna Simone Jones, Konrad Paul Kording

Any function can be constructed using a hierarchy of simpler functions through compositions.
