InstructCoder: Instruction Tuning Large Language Models for Code Editing

Core Concepts
Large Language Models can significantly improve code editing accuracy when fine-tuned with InstructCoder.
InstructCoder introduces a dataset for instruction finetuning to enhance code editing abilities of Large Language Models (LLMs). The dataset contains diverse code-editing tasks and scenarios sourced from GitHub commits and machine-generated data. Fine-tuning LLMs with InstructCoder results in significant improvements in code editing accuracy, outperforming models trained on raw GitHub commits. The dataset is shown to be effective in enhancing the performance of open-source models, matching advanced proprietary LLMs.
InstructCoder comprises over 114,000 instruction-input-output triplets. Code LLaMA achieves an accuracy of 57.22% after fine-tuning with InstructCoder.
"Open-source LLMs fine-tuned on InstructCoder can significantly enhance the accuracy of code edits." "In addressing this challenge, we present InstructCoder, a diverse dataset for instruction finetuning."

How can the effectiveness of machine-generated data in instruction tuning be further optimized?

Machine-generated data has proven to be effective in instruction tuning for code editing tasks. To further optimize its effectiveness, several strategies can be implemented: Diverse Prompt Design: Crafting diverse and well-structured prompts is crucial for generating high-quality machine-generated data. By designing prompts that cover a wide range of code-editing scenarios and instructions, the generated data will be more comprehensive and relevant. Quality Control Mechanisms: Implementing robust quality control mechanisms during the generation process can help filter out low-quality or irrelevant data. Techniques such as deduplication, semantic similarity checks, and human validation can ensure the generated data meets high standards. Scenario Integration: Incorporating specific scenarios into the prompt design can enhance the relevance and applicability of the generated instructions. By providing contextually rich scenarios, models are better equipped to generate accurate and meaningful instructions. Iterative Refinement: Adopting an iterative approach where initial machine-generated data is used to prompt subsequent generations allows for continuous improvement in dataset quality. This feedback loop enables refinement based on previous outputs, leading to enhanced performance over time. Data Augmentation Techniques: Leveraging techniques like back-translation, paraphrasing, or adding noise to existing prompts can diversify the training data further and improve model generalization capabilities.


機械生成データはコード編集タスクの指示調整において効果的であることが証明されています。その効果をさらに最適化するために、以下の戦略が実装されることがあります: 1.多様なプロンプト設計:多岐にわたるコード編集シナリオや指示をカバーするような多様かつ良く組み立てられたプロンプトの設計は重要です。幅広いコード編集シナリオや指示をカバーするプロンプトを設計することで、生成されるデータはより包括的で関連性が高くなります。 2.品質管理メカニズム:生成プロセス中の堅牢な品質管理メカニズムを導入することで、低品質または関連性の低いデータを取り除くことが可能です。重複排除、意味類似性チェック、人間による承認などの手法を用いることで、生成されたデータが高い基準を満たすよう保証します。 3.シナリオ統合:特定のシナリオをプロンプト設計に取り込むことは、生成された指示文書の関連性や適用可能性向上へ貢献します。文脈豊かなシナリオ提供によってモデルは正確かつ意味深い指示文書を生成する能力が向上します。 4.反復的改善:初期段階から後続世代へ影韓し新しく作成したマッヒングジェネレーティドテイダタ(MGT) を使用してフィードバックループ内では前回出力内容から修正し次第改善して行くアウチャートも採択しましょう 5. デーショント増強技術: バック・トランスレイション,パラフレージング,既存 の提示情報へ雑音追加等技術活用方法利用して 訓練テイダタ更分散化及びモデル汎化能力向上

What are potential limitations of using real-world GitHub commit data for instruction fine-tuning?

While real-world GitHub commit data provides valuable insights into actual code changes made by developers, there are several limitations associated with using this type of data for instruction fine-tuning: Noise and Irrelevance: Commit messages on GitHub may contain noise or lack detailed descriptions related to code edits, making it challenging to extract precise instructions from them. 2 . Multi-file Contexts: Real-world commits often involve changes across multiple files or complex interactions between different parts of a project which might not align well with single-task focused fine-tuning objectives. 3 . Limited Diversity: The scope of commit messages may not cover a broad spectrum of code editing tasks required for comprehensive instruction tuning. 4 . Licensing Issues: Some repositories on GitHub may have licensing restrictions that limit access or usage rights for research purposes. 5 . Quality Variability : The quality consistency among different commits varies significantly depending on individual developer practices which could impact model performance negatively 6 . Scalability Challenges : Processing large volumes of raw commit history requires significant computational resources which could hinder scalability especially when dealing with massive datasets 7 . Lack Of Ground Truth Labels : In many cases ,the ground truth labels needed for supervised learning approaches might not exist within these commits thus limiting their utility in certain types if ML applications These limitations highlight the importance o fcomplementing real-world dat sources with carefully curated machin egenerated datasets tto address gaps inherent i nusing raw commiit histories alone
