Ranking a Set of Objects using Heterogeneous Workers: QUITE an Easy Problem

no code implementations3 Oct 2023 Alessandro Nordio, Alberto Tarable, Emilio Leonardi

We focus on the problem of ranking $N$ objects starting from a set of noisy pairwise comparisons provided by a crowd of unequal workers, each worker being characterized by a specific degree of reliability, which reflects her ability to rank pairs of objects.

Federated Learning under Heterogeneous and Correlated Client Availability

1 code implementation11 Jan 2023 Angelo Rodio, Francescomaria Faticanti, Othmane Marfoq, Giovanni Neglia, Emilio Leonardi

To this purpose, CA-Fed dynamically adapts the weight given to each client and may ignore clients with low availability and large correlation.

Content Placement in Networks of Similarity Caches

no code implementations9 Feb 2021 Michele Garetto, Emilio Leonardi, Giovanni Neglia

Similarity caching systems have recently attracted the attention of the scientific community, as they can be profitably used in many application contexts, like multimedia retrieval, advertising, object recognition, recommender systems and online content-match applications.

Ranking a set of objects: a graph based least-square approach

no code implementations26 Feb 2020 Evgenia Christoforou, Alessandro Nordio, Alberto Tarable, Emilio Leonardi

We propose a class of non-adaptive ranking algorithms that rely on a least-squares optimization criterion for the estimation of qualities.

Selecting the top-quality item through crowd scoring

no code implementations23 Dec 2015 Alessandro Nordio, Alberto Tarable, Emilio Leonardi, Marco Ajmone Marsan

We investigate crowdsourcing algorithms for finding the top-quality item within a large collection of objects with unknown intrinsic quality values.
