PLM-based World Models for Text-based Games (2022.emnlp-main)
Copied to clipboard
| Challenge: | a new study shows that pre-trained world models provide a strong base for world models . worldformer is a text-based game environment that can be used to learn world models in text-driven games. |
| Approach: | They propose to use pre-trained language models to build world models in text-based game environments. |
| Outcome: | The proposed model outperforms state-of-the-art model-free algorithms in Atari games while retaining sample efficiency. |
PROMPRINT: Prompt Fingerprinting via First-Token Response for LLM App Cloning Detection (2026.acl-long)
Copied to clipboard
| Challenge: | Large Language Model apps are increasingly regarded as intellectual property . cloned apps pose risks of copyright infringement and malicious misuse . |
| Approach: | They propose a fingerprinting approach that optimizes queries that induce the LLM to generate a specific first token associated with the given system prompt. |
| Outcome: | The proposed fingerprinting approach is robust to partial system prompt modifications and effective under injection of adversarial instructions. |
