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, $k$-cen

We study the problem of decomposing a graph into stars so that the minimum size star in the decomposition is as large as possible. Problems of graph decomposition have been actively investigated since the 70’s. The question we consider here also co

This erratum fixes a technical problem in the paper published in Algorithmica, Volume 79, Number 3, November 2017, pp. 886–908. Theorem 1 of this paper gives upper bounds on both worst testing cost and expected testing cost of the decision tree bui

Oblivious decision trees are decision trees where every node in the same level is associated with the same attribute. These trees have been studied in the context of feature selection. In this paper, we study the problem of constructing an oblivious

Reservoir modeling is a very important task that permits the representation of a geological region of interest, so as to generate a considerable number of possible scenarios. Since its inception, many methodologies have been proposed and, in the last

Decision trees are a central structure in computer science, having applications in many areas. This thesis contributes to the understanding of this important structure by proving by proving theoretical bounds on its behavior and also providing algori

The cost of a test in a decision tree can depend on its result (value).We provide an O ( log ? ( n ) ) approximation for binary tests and value dependent costs.We provide an n approximation for multiway tests and value dependent costs. We study the p
An impurity measures $I: \mathbb {R}^{d} \mapsto \mathbb {R}^{+}$ is a function that assigns a $d$ -dimensional vector $\mathbf {v}$ to a non-negative value $I(\mathbf {v})$ so that the more homogeneous $\mathbf {v}$ , with respect to the values of i

The computation of convolutions is a fundamental problem that arises in applications from different fields as digital signal processing, image processing and string processing, among others. Here, we provide an in-depth investigation of the potential
