Continued pre-training (CPT) helps, but it rarely lifts harder skills like math reasoning, partly because low-resource corpora cover few domains. The authors build AfriqueLLM, a family of open models that use CPT over a 26B-token corpus to target 20… 3. **[Feedback Is The Key for Automated Survey Generation](https://md.research.elamur.ai/free/en/papers/xu-2026-feedback-is-key-automated-survey/)** *(2026)* LLM-based survey writers such as AutoSurvey, SurveyX and SurveyForge usually draft in one forward pass. Their output therefore often contains hallucinated claims, weak citations and loose structure. FIKSurvey adds the review-and-revise cycle that human authors rely on. A Writer LLM produces the text, and a separate… ## Co-authors here 10 co-authors with a page, the most papers together first. - [David Ifeoluwa Adelani](https://md.research.elamur.ai/free/en/authors/david-ifeoluwa-adelani/) - [Guoxiong Gao](https://md.research.elamur.ai/free/en/authors/guoxiong-gao/) - [Hao Yu](https://md.research.elamur.ai/free/en/authors/hao-yu/) - [Haocheng Ju](https://md.research.elamur.ai/free/en/authors/haocheng-ju/) - [Jiedong Jiang](https://md.research.elamur.ai/free/en/authors/jiedong-jiang/) - [Michael A.
