Explainable k-Means and k-Medians Clustering

no code implementations ICML 2020 Michal Moshkovitz, Sanjoy Dasgupta, Cyrus Rashtchian, Nave Frost

In terms of negative results, we show that popular top-down decision tree algorithms may lead to clusterings with arbitrarily large cost, and we prove that any explainable clustering must incur an \Omega(\log k) approximation compared to the optimal clustering.

Framework for Evaluating Faithfulness of Local Explanations

no code implementations1 Feb 2022 Sanjoy Dasgupta, Nave Frost, Michal Moshkovitz

We study the faithfulness of an explanation system to the underlying prediction model.

ExKMC: Expanding Explainable $k$-Means Clustering

2 code implementations3 Jun 2020 Nave Frost, Michal Moshkovitz, Cyrus Rashtchian

To allow flexibility, we develop a new explainable $k$-means clustering algorithm, ExKMC, that takes an additional parameter $k' \geq k$ and outputs a decision tree with $k'$ leaves.

Explainable $k$-Means and $k$-Medians Clustering

3 code implementations28 Feb 2020 Sanjoy Dasgupta, Nave Frost, Michal Moshkovitz, Cyrus Rashtchian

In terms of negative results, we show, first, that popular top-down decision tree algorithms may lead to clusterings with arbitrarily large cost, and second, that any tree-induced clustering must in general incur an $\Omega(\log k)$ approximation factor compared to the optimal clustering.
