若干可解释聚类问题的计算复杂性

The computational complexity of some explainable clustering problems

PUC-Rio(里约热内卢天主教大学)

Eduardo Sany Laber

摘要:

我们在[Dasgupta et al.,ICML 2020],其中通过轴对齐的决策树实现可解释性。我们考虑了$k$ -均值、$k$ -中位数、$k$ -中心和间隔代价函数。我们证明了前三个是很难优化,而后者可以在多项式时间内优化。

英文摘要:

We study the computational complexity of some explainable clustering problems in the framework proposed by [Dasgupta et al., ICML 2020], where explainability is achieved via axis-aligned decision trees. We consider the $k$-means, $k$-medians, $k$-centers and the spacing cost functions. We prove that the first three are hard to optimize while the latter can be optimized in polynomial time.
