| # CPRet-Embeddings |
|
|
| This repository provides the **problem descriptions** and their corresponding **precomputed embeddings** used by the [CPRet](https://github.com/coldchair/CPRet) retrieval server. |
|
|
| You can explore the retrieval server via the online demo at https://cpret.online/. |
|
|
| ## 📦 Files |
|
|
| * `probs_2606.jsonl` |
| A JSONL file containing natural language descriptions of competitive programming problems. |
| Each line is a JSON object with metadata such as problem title, platform/source OJ, URL, and full description. |
|
|
| * `probs_2606_embs.npy` |
| A NumPy array of dense embeddings corresponding to each problem in `probs_2606.jsonl`. |
| These embeddings are generated using the model [coldchair16/CPRetriever-Prob-Qwen3-4B-2510](https://huggingface.co/coldchair16/CPRetriever-Prob-Qwen3-4B-2510). |
|
|
| ## 🧠 Embedding Model |
|
|
| The embeddings in this repository are computed with: |
|
|
| * [coldchair16/CPRetriever-Prob-Qwen3-4B-2510](https://huggingface.co/coldchair16/CPRetriever-Prob-Qwen3-4B-2510) |
|
|
| ## 🌐 Problem Sources (OJ) |
|
|
| The current `2606` problem set includes problems from the following online judges: |

|
| ## 🗂️ Versioning & Naming Convention |
|
|
| This repository uses a **YYMM** naming convention for dataset versions: |
|
|
| - `YY` = last two digits of the year |
| - `MM` = month |
|
|
| This repository keeps the **latest version** as well as **historical versions** of problem sets and embeddings for reproducibility and backward compatibility. |
