 | 4) **The Capacity for Moral Self-Correction in Large Language Models** - finds strong evidence that language models trained with RLHF have the capacity for moral self-correction. The capability emerges at 22B model parameters and typically improves with scale.  | [Paper](https://arxiv.org/abs/2302.07459), [Tweet](https://twitter.com/dair_ai/status/1627671319100768260?s=20)  |
 | 6) **Language Quantized AutoEncoders: Towards Unsupervised Text-Image Alignment** - an unsupervised method for text-image alignment that leverages pretrained language models; it enables few-shot image classification with LLMs.   | [Paper](https://arxiv.org/abs/2302.00902) , [Code](https://github.com/lhao499/lqae) [Tweet](https://twitter.com/haoliuhl/status/1625273748629901312?s=20)  |
