What is VulBERTa-MLP-Devign?
VulBERTa-MLP-Devign is a specialized deep learning model designed for detecting security vulnerabilities in source code. Based on the RoBERTa architecture, it combines a pre-trained transformer model with an MLP (Multi-Layer Perceptron) classification head, specifically optimized for analyzing C/C++ code.
Implementation Details
The model utilizes a custom tokenization pipeline that includes automatic comment removal and specialized code processing. It requires libclang for tokenization and must be initialized with trust_remote_code=True due to its custom components.
- Pre-trained on real-world code from open-source C/C++ projects
- Implements binary classification for vulnerability detection
- Achieves 64.71% accuracy and 71.02% ROC-AUC score
- Uses F32 tensor type for computations
Core Capabilities
- Automated vulnerability detection in C/C++ source code
- Deep semantic code analysis
- Binary classification of secure vs vulnerable code segments
- Support for complex code structures and patterns
Frequently Asked Questions
