Sparsest cut and eigenvalue multiplicities on low degree Abelian Cayley graphs
Tommaso d'Orsi, Chris Jones, Jake Ruotolo +2
Whether or not the Sparsest Cut problem admits an efficient -approximation algorithm is a fundamental algorithmic question with connections to geometry and the Unique Games C…
Multi-View Stochastic Block Models
Vincent Cohen-Addad, Tommaso d'Orsi, Silvio Lattanzi +1
Graph clustering is a central topic in unsupervised learning with a multitude of practical applications. In recent years, multi-view graph clustering has gained a lot of attention…
A Near-Linear Time Approximation Algorithm for Beyond-Worst-Case Graph Clustering
Vincent Cohen-Addad, Tommaso d'Orsi, Aida Mousavifar
We consider the semi-random graph model of [Makarychev, Makarychev and Vijayaraghavan, STOC'12], where, given a random bipartite graph with edges and an unknown bipartition $(A…
Perturb-and-Project: Differentially Private Similarities and Marginals
Vincent Cohen-Addad, Tommaso d'Orsi, Alessandro Epasto +2
We revisit the input perturbations framework for differential privacy where noise is added to the input and the result is then projected back to the space of adm…
Private graphon estimation via sum-of-squares
Hongjie Chen, Jingqiu Ding, Tommaso d'Orsi +3
We develop the first pure node-differentially-private algorithms for learning stochastic block models and for graphon estimation with polynomial running time for any constant numbe…
Max-Cut with -Accurate Predictions
Vincent Cohen-Addad, Tommaso d'Orsi, Anupam Gupta +2
We study the approximability of the MaxCut problem in the presence of predictions. Specifically, we consider two models: in the noisy predictions model, for each vertex we are give…
