Hand-labelled corpora such as SemEval-18 and iSarcasm are clean but contain only a few thousand texts. Hashtag-harvested corpora such as Ptáček and Ghosh are large but noisy. The authors transfer knowledge from the large noisy sets to the small clean ones using adversarial… 2. **[Efficient RLHF: Reducing the Memory Usage of PPO](https://md.research.elamur.ai/free/en/papers/santacroce-2023-efficient-rlhf-reducing-memory-usage/)** *(2023 · 20 citations)* RLHF with PPO is costly. The PPO stage keeps an actor, a critic, a frozen reference policy and a frozen reward model in memory at once, so it needs more than three times the memory of supervised fine-tuning. That puts it out of reach for many teams. The Microsoft authors measure how several memory-saving variants… ## 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. **[FedVision: An Online Visual Object Detection Platform Powered by Federated Learning ↗](https://doi.org/10.1609/aaai.v34i08.7021) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Yang Liu et al.*2020 · 307 citations* 2. **[Contribution-Aware Federated Learning for Smart Healthcare ↗](https://doi.org/10.1609/aaai.v36i11.21505) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Zelei Liu et al.*2022 · 86 citations* 3. **[Crowdsensing Air Quality with Camera-Enabled Mobile Devices ↗](https://doi.org/10.1609/aaai.v31i2.19102) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Zhengxiang Pan et al.*2017 · 68 citations* 4. **[Latent-Optimized Adversarial Neural Transfer for Sarcasm Detection](https://md.research.elamur.ai/free/en/papers/guo-2021-latent-optimized-adversarial-neural-transfer/) [Conference of the North American Chapter of the Association for Computational Linguistics (NAACL)](https://md.research.elamur.ai/free/en/venues/naacl/)**Xu Guo, Boyang Li, Han Yu, et al.*2021 · 27 citations* 5.
