Recent Progress on Correlation Clustering: From Local Algorithms to Better Approximation Algorithms and Back (Invited Talk)
No full textCorrelation clustering is a classic model for clustering problems arising in machine learning and data mining. Given a set of data elements represented as vertices of a graph and pairwise similarity represented as edges, the goal is to find a partition of the vertex set so as to minimize the total number of edges across the parts plus the total number of non-edges within the parts.
Introduced in the early 2000s [Bansal et al., 2004], correlation clustering has received a large amount of attention through the years. A natural linear programming relaxation was shown to have an integrality gap of at least 2 and at most 2.5 [Ailon et al., 2008] in 2005, and in 2015 at most 2.06 [Chawla et al., 2015].
In 2021, motivated by large-scale application new structural insights allowed to derive a simple, practical algorithm that achieved an O(1)-approximation in a variety of models (Massively Parallel, Sublinear, Streaming or Differentially-private) [Vincent Cohen{-}Addad et al., 2021; Cohen-Addad et al., 2022]. These new insights turned out to be a key building block in designing better algorithms: It serves as a pre-clustering of the input graph that enables algorithm with approximation guarantees significantly better than 2 [Vincent Cohen{-}Addad et al., 2023; Vincent Cohen{-}Addad et al., 2022]. It is a key component in the new algorithm that achieves a 1.44-approximation [Nairen Cao et al., 2024] and in the new local-search based 1.84-approximation for the Massively Parallel, Sublinear, and Streaming models [Vincent Cohen{-}Addad et al., 2024]. This talk will review the above recent development and what are the main open research directions.

O modelo geopolítico de Cohen e a geoeconomia
No full textResPublica : Revista Lusófona de Ciência Política, Segurança e Relações InternacionaisO objetivo do presente ensaio é caraterizar o pensamento geopolítico de Saul B. Cohen (com particular enfoque nos principais conceitos teóricos que este apresenta), bem como as visões mais recentes da geoeconomia, de forma a identificar eventuais pontos de contacto. Assim, na primeira parte começamos por descrever, em termos gerais, o modelo geopolítico preconizado por Cohen, desde as suas origens até ao presente. A segunda parte é dedicada à geoeconomia e às suas principais características, nomeadamente no que se refere à relação entre os fatores económicos e os fatores geopolíticos. Na terceira parte são identificados alguns dos pontos em comum entre o modelo de Cohen e a Geoeconomia, recorrendo à análise e observação de mapas e gráficos. Por fim, serão apresentadas as principais conclusões resultantes da análise efetuada.The present essay’s purpose is to describe the geopolitical thought of Saul B. Cohen (particularly focused on his theoretical concepts), as well as the most recent geoeconomic views, in order to identify possible points of coincidence. Thus, in the first part we will start by describing in broad terms the geopolitical model advocated by this author. The second part is devoted to geoeconomy and its main features, specifically regarding the link between economic and geopolitical factors. In the third part we will identify some of the main common points between Cohen’s geopolitical model and the recent geoeconomic approaches, using and analyzing charts and graphics. In the end, we will present the main conclusions from the conducted analysis
