ASTER_4B is an independent reproduction of the ASTER framework. This model is fine-tuned based on Qwen/Qwen3-4B-Thinking-2507, strictly adhering to the experimental details and hyperparameter settings described in the original ASTER paper.
⚠️ Note: This is a reproduction project. We aim to verify the effectiveness of the ASTER method by strictly following the official paper's details.
Training Data (SFT)
The model was trained using our reproduced dataset: Aster_SFT4K.
This dataset serves as a tiny yet effective SFT set, constructed to replicate the exact data distribution and formatting used in the original ASTER experiments. You can find the dataset details here:
We evaluated the model's performance on challenging mathematical benchmarks. The evaluation was conducted under the exact generation configuration specified in the ASTER paper to ensure fair comparison.
