| Challenge: | Recent progress in large language models is driven by scaling of training compute through pre-training with nexttoken prediction (NTP) or post-training (RL) Pre-training using NTP enables models to acquire extensive knowledge and skills from general data, but it suffers from data inefficiency and catastrophic forgetting in continual learning settings. |
| Approach: | They propose to scale training compute through pre-training with next-token prediction (NTP) or post-training by scaling reinforcement learning (RL) to improve learning from general data. |
| Outcome: | Experiments on multiple benchmarks and models show that the proposed approach improves continual pre-training and provides a strong foundation for post-training on Qwen3-8B-Base. |
Distribution Shift Alignment Helps LLMs Simulate Survey Response Distributions (2026.findings-acl)

| Challenge: | Existing methods to simulate survey responses are based on zero-shot methods, but they are sensitive to prompt changes and deviate from the real-world distributions. |
| Approach: | They propose a distribution shift alignment method that aligns both the output distributions and the distribution shifts across different backgrounds to provide results closer to the true distribution than the training data. |
| Outcome: | The proposed method outperforms zero-shot methods on five public survey datasets and reduces the required real data by 53.48-69.12%. |
