TransformCode: A Contrastive Learning Framework for Code Embedding via Subtree Transformation

1 code implementation10 Nov 2023 Zixiang Xian, Rubing Huang, Dave Towey, Chunrong Fang, Zhenyu Chen

Our framework has several advantages over existing methods: (1) It is flexible and adaptable, because it can easily be extended to other downstream tasks that require code representation (such as code-clone detection and classification); (2) it is efficient and scalable, because it does not require a large model or a large amount of training data, and it can support any programming language; (3) it is not limited to unsupervised learning, but can also be applied to some supervised learning tasks by incorporating task-specific labels or objectives; and (4) it can also adjust the number of encoder parameters based on computing resources.
