| # ReSyn — Router |
|
|
| This repository contains the pre-trained **Router** model presented in the paper [ReSyn: A Generalized Recursive Regular Expression Synthesis Framework](https://huggingface.co/papers/2603.24624). |
|
|
| ReSyn is a synthesizer-agnostic divide-and-conquer framework that decomposes complex regular expression synthesis problems into manageable sub-problems by adaptively predicting whether to split examples sequentially (Concatenation) or group them by structural similarity (Union). |
|
|
| **Router** decides *how* to decompose a synthesis problem. Given a set of positive example strings, it classifies the set into one of three actions — **Concat**, **Union**, or **No-Op** — telling the framework whether to split the examples sequentially, group them by structural similarity, or synthesize them directly without further decomposition. |

| ## Usage |
|
|
| These are custom PyTorch models that use [`PyTorchModelHubMixin`](https://huggingface.co/docs/huggingface_hub/package_reference/mixins#huggingface_hub.PyTorchModelHubMixin). The model class is defined in the [GitHub repository](https://github.com/mrseongminkim/ReSyn); clone it first so that the `ReSyn` package is importable, then: |
|
|
| ```python |
| from ReSyn.model import Router |
| |
| model = Router.from_pretrained("mrseongminkim/ReSyn-Router").eval() |
| ``` |
|
|
| See [`ReSyn/server.py`](https://github.com/mrseongminkim/ReSyn/blob/main/ReSyn/server.py) for the full input encoding / output decoding used at inference time. |
