摘要：扩散模型变革了文本–图像生成领域,使终端用户可以基于简单的自然语言提示生成高质量、多样化的图像艺术作品.然而,由于训练数据集庞大且未经过滤,文本–图像生成模型具有生成色情内容与暴力内容等不适当内容的能力.为更加安全地部署此类模型,提出了一种基于CLIP (contrastive languageimage pre-training)方向性损失的微调(directional CLIP loss based fine-tuning, CLIF)算法,使用方向性的CLIP损失来微调模型,以抑制其生成不适当内容的能力. CLIF消耗的计算资源很少,并且具有强制生效的特点.为评估其抑制效果,提出了CTP (categorized toxic prompts)用于评估文本–图像生成模型的不适当内容生成能力.在CTP与COCO (common objects in context)上的实验结果表明, CLIF能够在抑制文本–图像扩散模型生成不安全内容的同时不影响其一般性生成能力.

摘要：In the transmitting, beamforming, and receiving combing （TBRC） MIMO system, a codebook based feedback strategy is usually used to provide the transmitter with the beamforming vector. The adopted codebook affects the system performance considerably. Therefore, the codebook design is a key technology in the TBRC MIMO system. In this article, the unitary space vector quantization （USVQ） codebook design criterion is proposed to design optimal codebooks for various spatial correlated MIMO channels. And the unitary space K-mean （USK） codebook generating algorithm is provided to generate the USVQ codebooks. Simulations show that the capacities of the feedback based TBRC systems using USVQ codebooks are very close to those of the ideal cases.
