High-quality datasets, tools, and concepts for LLM fine-tuning.

Data is the most valuable asset in LLM development. While datasets can't be directly evaluated like models, high-quality datasets have the following characteristics:

• Accuracy: Samples should be factually correct, helpful to users, and well-written. Answers should also be relevant to their corresponding instructions.
• Diversity: You want to cover as many use cases as possible to ensure proper instruction-following and relevant answers. This requires a wide range of topics, contexts, lengths, writing styles, etc. sampled in a representative way.
• Complexity: The dataset should be representative of the language and tasks you expect the model to handle. It should include common language usage (everyday language), real-world scenarios (e.g., books, articles, websites, social media, conversation transcripts), and a variety of text lengths to help the model handle various input sizes.

Measuring accuracy can be easy in the case of mathematical problems using a Python interpreter, or near-impossible with open-ended, subjective questions. On the other hand, clustering datasets by topic is a good way of measuring diversity. Finally, complexity is difficult to assess without involving frontier models.

Once a model has been pre-trained on a next-token prediction task, supervised fine-tuning is used to turn it into an assistant capable of answering questions and achieving tasks. These datasets contain pairs of instructions and outputs to train LLMs to go beyond their pre-training objective. All the datasets listed here should be under permissive licensing (Apache 2.0, MIT, cc-by-4.0, etc.).

The goal of general-purpose datasets is to transform base models into versatile and capable assistants by exposing them to a wide range of high-quality data. These datasets often include a diverse mix of real-world and synthetic data, commonly generated using models like GPT-4.

LLMs often struggle with mathematical reasoning and formal logic, which has led to the creation of specialized datasets. These datasets extend beyond pure mathematics, encompassing a wide range of problems that require systematic thinking and step-by-step reasoning, ultimately enabling LLMs to tackle complex real-world challenges that involve logical deduction and quantitative analysis.

Many datasets focus on pairs of instructions and outputs, but chat models are often used in conversational settings. Conversational and role-play datasets expose LLMs to the patterns, nuances, and context-dependent nature of real conversations, allowing them to generate more natural, and engaging dialogues.

Function calling allows large language models (LLMs) to execute predefined functions with parameters inferred from user prompts, rather than generating standard text responses. This enables LLMs to seamlessly integrate with external systems, perform complex operations, and provide more accurate and contextually relevant responses.

W.I.P.

To create a high-quality dataset, focus on carefully curating a diverse set of relevant, accurate and informative examples rather than simply maximizing dataset size.

Start by aggregating available data from various sources (open-source or not) and apply filters like data deduplication and data quality. If the initial dataset is small or insufficient, consider synthetically generating additional data that mirrors its quality and style. Iteratively explore and refine the dataset by assessing model performance, identifying gaps and collecting or generate data to address those shortcomings.

• MinHash: fuzzy deduplication with hashing, sorting, and Jaccard similarity (preferred technique).
• BLOOM filters: fuzzy deduplication with hashing and fixed-size vector.
• Sentence deduplication: exact sentence matching.

• Rule-based filtering: Remove samples based on a list of unwanted words, like refusals and "As an AI assistant" (example).
• Argilla: Open-source data curation platform that allows you to filter and annotate datasets in a collaborative way.
• Using LLM-as-a-judge: Colab notebook that provides code to rate outputs with Mixtral-7x8B.

• Lilac: Tool to curate better data for LLMs, used by NousResearch, databricks, cohere, Alignment Lab AI. It can also apply filters.
• Nomic Atlas: Interact with instructed data to find insights and store embeddings.
• text-clustering: Embed, cluster, and label text datasets using Sentence Transformers, UMAP, DBSCAN, and an LLM.
• BunkaTopics: Data cleaning and topic modeling visualization.

• Distilabel: General-purpose framework that can generate and augment data (SFT, DPO) with techniques like UltraFeedback and DEITA.
• Auto Data: Lightweight library to automatically generate fine-tuning datasets with API models.
• Bonito: Library for generating synthetic instruction tuning datasets for your data without GPT (see also AutoBonito).
• Augmentoolkit: Framework to convert raw text into datasets using open-source and closed-source models.
