Uncovering latent consensus in heterogeneous populations: The Mixture Linear Ordering Problem
Juan A. Aledo, Concepción DomÃnguez, Juan de Dios Jaime-Alcántara +1
The classical linear ordering problem seeks a single ranking representing a given preference matrix. While suitable for homogeneous populations, it fails when observed preferences…
An optimization-based approach to ranking aggregation with weak order outputs
Juan A. Aledo, Concepción DomÃnguez, Juan de Dios Jaime-Alcántara +1
Rank aggregation problems combine conflicting rankings of items into a single consensus ranking. In many applications, forcing all items into a strict order is too restrictive, sin…
Bayesian Network Structural Consensus via Greedy Min-Cut Analysis
Pablo Torrijos, José M. Puerta, Juan A. Aledo +1
This paper presents the Min-Cut Bayesian Network Consensus (MCBNC) algorithm, a greedy method for structural consensus of Bayesian Networks (BNs), with applications in federated le…
A consensus set for the aggregation of partial rankings: the case of the Optimal Set of Bucket Orders Problem
Juan A. Aledo, José A. Gámez, Alejandro Rosete
In rank aggregation problems (RAP), the solution is usually a consensus ranking that generalizes a set of input orderings. There are different variants that differ not only in term…
