 This repository contains the implementation of a novel approach for source code similarity detection that integrates an additional output feature into the classification process to enhance model performance. The approach is based on the **GraphCodeBERT** model, which has been extended with a custom output feature layer and a concatenation mechanism to improve feature representation. The model has been trained and evaluated on the **IR-Plag dataset**, demonstrating significant improvements in precision, recall, and f-measure. The full implementation, including model architecture, training strategies, and evaluation metrics, is available in this repository.
