研究方向简介：

1）生成式大模型理论研究：

混合模型协同方法研究：通过整合不同类型的人工智能模型(例如，预训练大模型、领域专用小横型、先验知识模块等) ，可以弥补大模型的不足。

2）生成式大模型应用研究：

文-图生图大模型用于教育领域，如教材生成：

  文-图生图大模型,应用于文创领域（刺绣、国画、唐卡、脸谱）：

3）生成式大模型数字内容安全：

生成式大模型中的数据样本保护，在扩散模型中嵌入内生水印和外置水印结合并进行联合训练，对数据进行有效的版权保护和溯源。

4）伪造视频检测：

 深度视频合成技术的滥用会给国防、军事、民生等多方面带来全新安全的挑战。基于深度生成网络和分类网络实现深度合成视频的主动和被动检测，相关成果对深度合成视频的安全管控有重要作用，是现在人工智能和AIGC安全方面研究热点问题。

5）图像视频指纹：

将数字内容版权保护视为二分类问题，基于深度学习网络提取图像视频数字内容的鲁棒性特征，实现对数字内容的的可靠保护，是人工智能在信息安全中应用的热点问题。

6）生成式信息隐藏方法：

 传统的信息隐藏会修改信息内容，无法达到可证的安全，会受到隐写分析器的威胁。而基于对抗式生成网络可以将特定的信息生成图像，并使用生成图像传递和还原秘密信息，从而实现可证安全的隐蔽通讯，是人工智能在信息安全中应用的热点问题。
