EpiCoder Meta Features is a dataset released by Microsoft in 2025, containing a hierarchical meta-feature classification system and corresponding frequency statistics. The related research paper is "EpiCoder: Encompassing Diversity and Complexity in Code Generation", designed to provide foundational support for controlled feature-conditioned code generation.

Dataset Composition

• epicoder_features.json: Defines a hierarchical classification system for 17 top-level code feature categories, covering dimensions such as programming language, implementation style, workflow, functionality, and resource usage.
• epicoder_features_frequency.json: Provides frequency statistics covering 1,795,310 feature nodes, including aggregated frequency, historical frequency, and average sub-feature frequency, used to capture fine-grained code features extracted from real-world code repositories.
