Mind the Data Gap: Bridging LLMs to Enterprise Data Integration

no code implementations29 Dec 2024 Moe Kayali, Fabian Wenz, Nesime Tatbul, Çağatay Demiralp

We show that, once these techniques are deployed, the performance on enterprise data becomes on par with that of public data.

BEAVER: An Enterprise Benchmark for Text-to-SQL

no code implementations3 Sep 2024 Peter Baile Chen, Fabian Wenz, Yi Zhang, Devin Yang, Justin Choi, Nesime Tatbul, Michael Cafarella, Çağatay Demiralp, Michael Stonebraker

However, how these results transfer to enterprise settings is unclear because tables in enterprise databases might differ substantially from web tables in structure and content.

Making LLMs Work for Enterprise Data Tasks

no code implementations22 Jul 2024 Çağatay Demiralp, Fabian Wenz, Peter Baile Chen, Moe Kayali, Nesime Tatbul, Michael Stonebraker

Large language models (LLMs) know little about enterprise database tables in the private data ecosystem, which substantially differ from web text in structure and content.

CascadeServe: Unlocking Model Cascades for Inference Serving

no code implementations20 Jun 2024 Ferdi Kossmann, Ziniu Wu, Alex Turk, Nesime Tatbul, Lei Cao, Samuel Madden

In the offline phase, the system pre-computes a gear plan that specifies how to serve inferences online.

Extract-Transform-Load for Video Streams

1 code implementation7 Oct 2023 Ferdinand Kossmann, Ziniu Wu, Eugenie Lai, Nesime Tatbul, Lei Cao, Tim Kraska, Samuel Madden

We find that no current system sufficiently fulfills both needs and therefore propose Skyscraper, a system tailored to V-ETL.

A Skew-Sensitive Evaluation Framework for Imbalanced Data Classification

1 code implementation12 Oct 2020 Min Du, Nesime Tatbul, Brian Rivers, Akhilesh Kumar Gupta, Lucas Hu, Wei Wang, Ryan Marcus, Shengtian Zhou, Insup Lee, Justin Gottschlich

Class distribution skews in imbalanced datasets may lead to models with prediction bias towards majority classes, making fair assessment of classifiers a challenging task.

LISA: Towards Learned DNA Sequence Search

no code implementations10 Oct 2019 Darryl Ho, Jialin Ding, Sanchit Misra, Nesime Tatbul, Vikram Nathan, Vasimuddin Md, Tim Kraska

Next-generation sequencing (NGS) technologies have enabled affordable sequencing of billions of short DNA fragments at high throughput, paving the way for population-scale genomics.

The Three Pillars of Machine Programming

no code implementations20 Mar 2018 Justin Gottschlich, Armando Solar-Lezama, Nesime Tatbul, Michael Carbin, Martin Rinard, Regina Barzilay, Saman Amarasinghe, Joshua B. Tenenbaum, Tim Mattson

In this position paper, we describe our vision of the future of machine programming through a categorical examination of three pillars of research.
