A Benchmark for Real-world Knowledge Injection](https://md.research.elamur.ai/free/en/papers/zhang-2026-bidirectional-lms-are-better-knowledge/)** *(2026 · 4 citations)* The paper asks how well language models can absorb new facts after pre-training. Earlier knowledge-injection studies mostly relied on synthetic data drawn from noisy Wikipedia snapshots, and their questions were often poorly specified. 2. **[C-World: A Computer Use Agent Environment Creator](https://md.research.elamur.ai/free/en/papers/xi-2026-c-world-computer-use-agent/)** *(2026)* LLM agents still fall short of humans at long-horizon planning, partly because training environments are few, narrow, and costly to build by hand. 3. **[Deriving Character Logic from Storyline as Codified Decision Trees](https://md.research.elamur.ai/free/en/papers/peng-2026-deriving-character-logic-storyline-as/)** *(2026)* Role-playing (RP) agents built on LLMs usually rely on free-text character profiles. These profiles are hard to verify, cannot be executed, and tend to mix behaviors from different situations, so agents act inconsistently. The authors propose Codified Decision Trees (CDT), which learn a character's behavioral logic… ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Jingbo Shang](https://md.research.elamur.ai/free/en/authors/jingbo-shang/) ×2 - [Kun Zhou](https://md.research.elamur.ai/free/en/authors/kun-zhou/) ×2 - [Biwei Huang](https://md.research.elamur.ai/free/en/authors/biwei-huang/) - [Gaowen Liu](https://md.research.elamur.ai/free/en/authors/gaowen-liu/) - [Jayanth Srinivasa](https://md.research.elamur.ai/free/en/authors/jayanth-srinivasa/) - [Lianhui Qin](https://md.research.elamur.ai/free/en/authors/lianhui-qin/) - [Qi Liu](https://md.research.elamur.ai/free/en/authors/qi-liu/) - [Shangbin Feng](https://md.research.elamur.ai/free/en/authors/shangbin-feng/) - [Shuang Liang](https://md.research.elamur.ai/free/en/authors/shuang-liang/) - [Tianhui Zhang](https://md.research.elamur.ai/free/en/authors/tianhui-zhang/) - [Wenhao Yu](https://md.research.elamur.ai/free/en/authors/wenhao-yu/) - [Yifan Zhu](https://md.research.elamur.ai/free/en/authors/yifan-zhu/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/) ×3: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×3 ## Cited by Papers of our library cite their works 4 times (of the 149,439 papers whose bibliographies we read); [1 citing paper with a page here →](https://md.research.elamur.ai/free/en/authors/letian-peng/cited-by/).
