**Llama-3.2-1B-Code-Knowledge-Value-Eval **

This model is a fine-tuned version of meta-llama/Llama-3.2-1B on the kimsan0622/code-knowledge-eval dataset. It achieves the following results on the evaluation set:

• Loss: 1.0447
• Accuracy: 0.5227

Model Description

The model trained on the Code Knowledge Value Evaluation Dataset is designed to assess the educational and knowledge value of code snippets. It leverages patterns and contextual information from a large collection of open-source code, sourced from the bigcode/the-stack repository. By analyzing these code samples, the model can evaluate their utility in teaching coding concepts, solving problems, and improving developer education.

The model focuses on understanding the structure, syntax, and logic of various programming languages, enabling it to provide insights into the learning potential and technical depth of different code samples. The dataset used for training consists of 22,786 samples for training, 4,555 for validation, and 18,232 for testing, ensuring that the model is both robust and well-generalized across different coding contexts.

Intended Uses & Limitations

Intended Uses:

1. Automated Code Review: The model can be applied in automated systems to assess the knowledge value of code during code review processes. It can help identify areas where code could be optimized for better readability, maintainability, and educational impact.
2. Educational Feedback: For instructors and educational platforms, the model can offer feedback on the effectiveness of code samples used in teaching, helping to improve curriculum materials and select code that best conveys core programming concepts.
3. Curriculum Development: The model can aid in designing coding courses or instructional materials by suggesting code examples that have higher educational value, supporting a more effective learning experience.
4. Technical Skill Assessment: Organizations or platforms can use the model to assess the complexity and educational value of code submissions in coding challenges or exams.

Limitations:

1. Narrow Scope in Knowledge Evaluation: The model is specialized in evaluating code from an educational standpoint, focusing primarily on learning potential rather than production-level code quality (e.g., performance optimization or security).
2. Language and Domain Limitations: Since the dataset is sourced from bigcode/the-stack, it may not cover all programming languages or specialized domains. The model may perform less effectively in underrepresented languages or niche coding styles not well-represented in the dataset.
3. Not Suitable for All Educational Levels: While the model is designed to evaluate code for educational purposes, its outputs may be better suited for certain levels (e.g., beginner or intermediate coding), and its recommendations might not fully cater to advanced or highly specialized learners.
