RAG vs Fine-tuning: Pipelines, Tradeoffs, and a Case Study on Agriculture

no code implementations16 Jan 2024 Angels Balaguer, Vinamra Benara, Renato Luiz de Freitas Cunha, Roberto de M. Estevão Filho, Todd Hendry, Daniel Holstein, Jennifer Marsman, Nick Mecklenburg, Sara Malvar, Leonardo O. Nunes, Rafael Padilha, Morris Sharp, Bruno Silva, Swati Sharma, Vijay Aski, Ranveer Chandra

Our pipeline consists of multiple stages, including extracting information from PDFs, generating questions and answers, using them for fine-tuning, and leveraging GPT-4 for evaluating the results.

GPT-4 as an Agronomist Assistant? Answering Agriculture Exams Using Large Language Models

no code implementations10 Oct 2023 Bruno Silva, Leonardo Nunes, Roberto Estevão, Vijay Aski, Ranveer Chandra

Our analysis highlights GPT-4's ability to achieve a passing score on exams to earn credits for renewing agronomist certifications, answering 93% of the questions correctly and outperforming earlier general-purpose models, which achieved 88% accuracy.

Model-Parallel Fourier Neural Operators as Learned Surrogates for Large-Scale Parametric PDEs

1 code implementation4 Apr 2022 Thomas J. Grady II, Rishi Khan, Mathias Louboutin, Ziyi Yin, Philipp A. Witte, Ranveer Chandra, Russell J. Hewett, Felix J. Herrmann

Fourier neural operators (FNOs) are a recently introduced neural network architecture for learning solution operators of partial differential equations (PDEs), which have been shown to perform significantly better than comparable deep learning approaches.

FedSpace: An Efficient Federated Learning Framework at Satellites and Ground Stations

no code implementations2 Feb 2022 Jinhyun So, Kevin Hsieh, Behnaz Arzani, Shadi Noghabi, Salman Avestimehr, Ranveer Chandra

To address these challenges, we leverage Federated Learning (FL), where ground stations and satellites collaboratively train a global ML model without sharing the captured images on the satellites.
