Judging completeness needs a full ground truth, but humans cannot reliably build one for such high-entropy queries. As a result, agents that find valid items missing from the annotated pool get marked as hallucinating. ## All works 5 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Less is More: Zero-Shot Learning from Online Textual Documents with Noise Suppression ↗](https://doi.org/10.1109/cvpr.2016.247) IEEE Computer Society Conference on Computer Vision and Pattern Recognition/Proceedings - IEEE Computer Society Conference on Computer Vision and Pattern Recognition/Proceedings · no summary yet**Ruizhi Qiao et al.*2016 · 183 citations* 2. **[HybridCR: Weakly-Supervised 3D Point Cloud Semantic Segmentation via Hybrid Contrastive Regularization ↗](https://doi.org/10.1109/cvpr52688.2022.01451) IEEE Computer Society Conference on Computer Vision and Pattern Recognition/Proceedings - IEEE Computer Society Conference on Computer Vision and Pattern Recognition/Proceedings · no summary yet**Mengtian Li et al.*2022 · 104 citations* 3. **[Comprehensive Regularization in a Bi-directional Predictive Network for Video Anomaly Detection ↗](https://doi.org/10.1609/aaai.v36i1.19898) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Cheng‐Wei Chen et al.*2022 · 74 citations* 4. **[HiChunk: Evaluating and Enhancing Retrieval Augmented Generation with Hierarchical Chunking](https://md.research.elamur.ai/free/en/papers/lu-2026-hichunk-evaluating-enhancing-retrieval-augmented/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Wensheng Lu, Keyu Chen, Zhifeng Shen, et al.*2026 · 4 citations* 5. **[Breaking the Evaluation Paradox: Evaluating High-Entropy Search with Computationally Irreducible Constraints](https://md.research.elamur.ai/free/en/papers/wu-2026-breaking-evaluation-paradox-evaluating-high/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Juntao Wu, Wei Wen, Xianting Huang, et al.*2026 · 1 citation* ## Co-authors here 3 co-authors with a page, the most papers together first. - [Xing Sun](https://md.research.elamur.ai/free/en/authors/xing-sun/) ×2 - [Ke Wang](https://md.research.elamur.ai/free/en/authors/ke-wang/) - [Keyu Chen](https://md.research.elamur.ai/free/en/authors/keyu-chen/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - IEEE Computer Society Conference on Computer Vision and Pattern Recognition/Proceedings - IEEE Computer Society Conference on Computer Vision and Pattern Recognition/Proceedings ×2 - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) - Proceedings of the AAAI Conference on Artificial Intelligence ## Cited by Papers of our library cite their works 13 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/ruizhi-qiao/cited-by/).
