Text-only and vision-only models such as BERT or ResNet cannot handle vision-language inputs. Multi-modal models such as ViLBERT and UNITER learn only from scarce image-text pairs and perform poorly when moved to pure language tasks. The authors (Baidu) propose… 2. **[Efficient Large Language Models: A Survey](https://md.research.elamur.ai/free/en/papers/wan-2023-efficient-large-language-models-survey/)** *(2023 · 110 citations)* Training and running LLMs with billions of parameters is costly. Using LLaMA data, the authors show that training compute rises steeply with model size while inference throughput falls. This survey maps research on cutting these costs and limits itself to techniques for billion-scale models rather than smaller… ## All works 4 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. **[UNIMO: Towards Unified-Modal Understanding and Generation via Cross-Modal Contrastive Learning](https://md.research.elamur.ai/free/en/papers/li-2021-unimo-unified-modal-understanding-generation/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Wei Li, Can Gao, Guocheng Niu, et al.*2021 · 308 citations* 2. **[Leveraging Graph to Improve Abstractive Multi-Document Summarization ↗](https://aclanthology.org/2020.acl-main.555/) Proceedings of the 58th Annual Meeting of the Association for Computational Linguistics · no summary yet**Wei Li et al.*2020 · 168 citations* 3.
