多代理行为建模旨在了解代理之间发生的交互。我们从行为神经科学，Caltech鼠标社交交互（CALMS21）数据集中提供了一个多代理数据集。我们的数据集由社交交互的轨迹数据组成，从标准居民入侵者测定中自由行为小鼠的视频记录。为了帮助加速行为研究，CALMS21数据集提供基准，以评估三种设置中自动行为分类方法的性能：（1）用于培训由单个注释器的所有注释，（2）用于风格转移以进行学习互动在特定有限培训数据的新行为学习的行为定义和（3）的注释差异。 DataSet由600万个未标记的追踪姿势的交互小鼠组成，以及超过100万帧，具有跟踪的姿势和相应的帧级行为注释。我们的数据集的挑战是能够使用标记和未标记的跟踪数据准确地对行为进行分类，以及能够概括新设置。

Diagnostic radiologists need artificial intelligence (AI) for medical imaging, but access to medical images required for training in AI has become increasingly restrictive. To release and use medical images, we need an algorithm that can simultaneously protect privacy and preserve pathologies in medical images. To develop such an algorithm, here, we propose DP-GLOW, a hybrid of a local differential privacy (LDP) algorithm and one of the flow-based deep generative models (GLOW). By applying a GLOW model, we disentangle the pixelwise correlation of images, which makes it difficult to protect privacy with straightforward LDP algorithms for images. Specifically, we map images onto the latent vector of the GLOW model, each element of which follows an independent normal distribution, and we apply the Laplace mechanism to the latent vector. Moreover, we applied DP-GLOW to chest X-ray images to generate LDP images while preserving pathologies.
