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.

Functional Collection Programming with Semi-Ring Dictionaries

no code implementations10 Mar 2021 Amir Shaikhha, Mathieu Huot, Jaclyn Smith, Dan Olteanu

We developed SDQL, a statically typed language that can express relational algebra with aggregations, linear algebra, and functional collections over data such as relations and matrices using semi-ring dictionaries.

This work is the outcome of extensive collaboration of the author with colleagues from RelationalAI, in particular Mahmoud Abo Khamis, Molham Aref, Hung Ngo, and XuanLong Nguyen, and from the FDB research project, in particular Ahmet Kara, Milos Nikolic, Maximilian Schleich, Amir Shaikhha, Jakub Zavodny, and Haozhe Zhang.

Rk-means: Fast Clustering for Relational Data

no code implementations11 Oct 2019 Ryan Curtin, Ben Moseley, Hung Q. Ngo, XuanLong Nguyen, Dan Olteanu, Maximilian Schleich

When the data matrix needs to be obtained from a relational database via a feature extraction query, the computation cost can be prohibitive, as the data matrix may be (much) larger than the total input relation size.

Declarative Statistical Modeling with Datalog

no code implementations6 Dec 2014 Vince Barany, Balder ten Cate, Benny Kimelfeld, Dan Olteanu, Zografoula Vagena

By virtue of extending Datalog, our framework offers a natural integration with the database, and has a robust declarative semantics.

10^(10^6) Worlds and Beyond: Efficient Representation and Processing of Incomplete Information

1 code implementation16 Jun 2006 Lyublena Antova, Christoph Koch, Dan Olteanu

Current systems and formalisms for representing incomplete information generally suffer from at least one of two weaknesses.
