Differentially Private Selection using Smooth Sensitivity
Iago Chaves, Victor Farias, Amanda Perez +2
Differentially private selection mechanisms offer strong privacy guarantees for queries aiming to identify the top-scoring element r from a finite set R, based on a dataset-depende…
Classification of User Reports for Detection of Faulty Computer Components using NLP Models: A Case Study
Maria de Lourdes M. Silva, André L. C. Mendonça, Eduardo R. D. Neto +4
Computer manufacturers typically offer platforms for users to report faults. However, there remains a significant gap in these platforms' ability to effectively utilize textual rep…
Differentially Private Multi-objective Selection: Pareto and Aggregation Approaches
Victor A. E. Farias, Felipe T. Brito, Cheryl Flynn +2
Differentially private selection mechanisms are fundamental building blocks for privacy-preserving data analysis. While numerous mechanisms exist for single-objective selection, ma…
b-coloring graphs with large girth
Victor Campos, Victor Farias, Ana Silva
A b-coloring of a graph is a coloring of its vertices such that every color class contains a vertex that has a neighbor in all other classes. The b-chromatic number of a graph is t…
