Fair Committee Selection under Ordinal Preferences and Limited Cardinal Information
Ameet Gadekar, Aristides Gionis, Suhas Thejaswi +1
We study the problem of fair -committee selection under an egalitarian objective. Given agents partitioned into groups (\eg, demographic quotas), the goal is to aggregat…
Label-consistent clustering for evolving data
Ameet Gadekar, Aristides Gionis, Thibault Marette
Data analysis often involves an iterative process, where solutions must be continuously refined in response to new data. Typically, as new data becomes available, an existing solut…
Fairness-aware PageRank via Edge Reweighting
Honglian Wang, Haoyun Chen, Aristides Gionis
Link-analysis algorithms, such as PageRank, are instrumental in understanding the structural dynamics of networks by evaluating the importance of individual vertices based on their…
DSP: A Statistically-Principled Structural Polarization Measure
Giulia Preti, Matteo Riondato, Aristides Gionis +1
Social and information networks may become polarized, leading to echo chambers and political gridlock. Accurately measuring this phenomenon is a critical challenge. Existing measur…
Efficient and Adaptive Estimation of Local Triadic Coefficients
Ilie Sarpe, Aristides Gionis
Characterizing graph properties is fundamental to the analysis and to our understanding of real-world networked systems. The local clustering coefficient, and the more recently int…
Sample and Expand: Discovering Low-rank Submatrices With Quality Guarantees
Martino Ciaperoni, Aristides Gionis, Heikki Mannila
The problem of approximating a matrix by a low-rank one has been extensively studied. This problem assumes, however, that the whole matrix has a low-rank structure. This assumption…
