## Overview

- This paper explores using large language models (LLMs) for data preprocessing (DP), a crucial step in the data mining pipeline.
- The authors propose using instruction-tuned local LLMs (7-13B models) as universal DP task solvers, addressing data security concerns with approaches that rely on GPT APIs.
- The models, called Jellyfish, are tuned on a collection of DP datasets and deliver performance comparable to GPT-3.5/4 while maintaining strong generalizability and reasoning capabilities.

## Plain English Explanation

Before machine learning models can be trained on data, that data needs to be preprocessed and cleaned up. This is an important but often overlooked step called **data preprocessing (DP)**. The authors of this paper wanted to find a better way to do DP using **large language models (LLMs)**, which are powerful AI models trained on vast amounts of text data.

Many recent approaches to using LLMs for DP have relied on the GPT API, which raises concerns about data security and privacy. Instead, the authors propose using **instruction-tuned local LLMs**, which are trained on a specific set of DP tasks and can run on a single, low-cost GPU. This allows the DP to be done locally without sending data to a remote server.

The authors trained their **Jellyfish** models on a collection of DP datasets, using techniques like [data configuration](https://aimodels.fyi/papers/arxiv/using-large-language-models-to-enrich-documentation), [knowledge injection](https://aimodels.fyi/papers/arxiv/prompt-public-large-language-models-to-synthesize), and [reasoning data distillation](https://aimodels.fyi/papers/arxiv/genshin-general-shield-natural-language-processing-large). The Jellyfish models perform about as well as the much larger GPT-3.5 and GPT-4 models on DP tasks, while also maintaining strong performance on general [natural language processing (NLP) tasks](https://aimodels.fyi/papers/arxiv/large-language-models-expansion-spoken-language-understanding). Additionally, the Jellyfish models show enhanced [reasoning capabilities](https://aimodels.fyi/papers/arxiv/annollm-making-large-language-models-to-be) compared to GPT-3.5.

## Technical Explanation

The paper explores using **instruction-tuned local LLMs** (7-13B models) as universal data preprocessing (DP) task solvers. This is in contrast to recent approaches that rely on GPT APIs, which raise data security concerns.

The authors select a collection of datasets across four representative DP tasks and construct **instruction tuning data** using techniques like data configuration, knowledge injection, and reasoning data distillation. They then tune **Mistral-7B**, **LLaMA 3-8B**, and **OpenOrca-Platypus2-13B** models, creating the **Jellyfish-7B/8B/13B** models.

The Jellyfish models deliver performance comparable to **GPT-3.5/4** on the DP tasks while maintaining strong generalizability to unseen tasks. They also show enhanced reasoning capabilities compared to GPT-3.5. The models are available on Hugging Face, and the instruction dataset is also publicly available.

## Critical Analysis

The paper presents a promising approach to using LLMs for data preprocessing in a secure and customizable manner. The authors' focus on instruction tuning local LLMs is a thoughtful response to the data security concerns raised by approaches using GPT APIs.

One potential limitation is the scope of the DP tasks covered. While the authors select a representative set, there may be other DP tasks or domain-specific requirements that are not addressed. Further research could explore the model's performance on a wider range of DP scenarios.

Additionally, the paper does not provide detailed benchmarks or comparisons to other state-of-the-art DP methods beyond GPT-3.5/4. Comparing the Jellyfish models to traditional DP techniques or other LLM-based approaches could give a more comprehensive understanding of their strengths and weaknesses.

Overall, the research presents a compelling approach to using LLMs for data preprocessing, and the publicly available models and datasets provide a valuable resource for further exploration and development in this area.

## Conclusion

This paper introduces a novel approach to using **large language models (LLMs)** for **data preprocessing (DP)**, a crucial step in the data mining pipeline. By leveraging **instruction-tuned local LLMs**, the authors have developed the **Jellyfish** models, which deliver performance comparable to much larger GPT-3.5 and GPT-4 models while ensuring data security and enabling further customization.

The Jellyfish models' strong generalizability and enhanced reasoning capabilities demonstrate the potential of this approach to serve as universal DP task solvers. The publicly available models and datasets provide a valuable resource for researchers and practitioners looking to improve data preprocessing workflows using advanced language AI.
