TransDPR: Design Pattern Recognition Using Programming Language Models

Paper in proceeding, 2023

Current Design Pattern Recognition (DPR) methods have limitations, such as the reliance on semantic information, limited recognition of novel or modified pattern versions, and other factors. We present an introductory DPR technique by using a Programming Language Model (PLM) called TransDPR, which utilizes a Facebook pre-trained model (TransCoder), which is a Cross-lingual programming Language Model (XLM) based on a transformer architecture. We leverage an n-dimensional vector representation of programs and apply logistic regression to learn design patterns (DPs). Our approach utilizes the GitHub repository to collect singleton and prototype DP programs written in C++ source code. Our results indicate that TransDPR achieves 90% accuracy and an F1-score of 0.88 on open-source projects. We evaluate the proposed model on two developed modules from Volvo Cars and invite the original developers to validate the prediction results.
