CHORUS: Foundation Models for Unified Data Discovery and Exploration

1 code implementation16 Jun 2023 Moe Kayali, Anton Lykov, Ilias Fountalis, Nikolaos Vasiloglou, Dan Olteanu, Dan Suciu

On all three tasks, we show that a foundation-model-based approach outperforms the task-specific models and so the state of the art.

On algorithmically boosting fixed-point computations

no code implementations4 Apr 2023 Ioannis Avramopoulos, Nikolaos Vasiloglou

Secondly, we restrict attention to convergent linear maps (for computing dominant eigenvectors, for example, in the PageRank algorithm) and show that our algorithmic boosting method can set in motion {\em exponential speedups in the convergence rate}.

Multi-way Interacting Regression via Factorization Machines

1 code implementation NeurIPS 2017 Mikhail Yurochkin, XuanLong Nguyen, Nikolaos Vasiloglou

We propose a Bayesian regression method that accounts for multi-way interactions of arbitrary orders among the predictor variables.

Practical Attacks Against Graph-based Clustering

no code implementations29 Aug 2017 Yizheng Chen, Yacin Nadji, Athanasios Kountouras, Fabian Monrose, Roberto Perdisci, Manos Antonakakis, Nikolaos Vasiloglou

Graph modeling allows numerous security problems to be tackled in a general way, however, little work has been done to understand their ability to withstand adversarial attacks.

ERBlox: Combining Matching Dependencies with Machine Learning for Entity Resolution

no code implementations7 Feb 2016 Zeinab Bahmani, Leopoldo Bertossi, Nikolaos Vasiloglou

Entity resolution (ER), an important and common data cleaning problem, is about detecting data duplicate representations for the same external entities, and merging them into single representations.
