    • Methods and systems for clustering information items using nonnegative tensor factorization are disclosed. A processing device receives one or more class labels, each corresponding to an information item, a selection for a nonnegative tensor factorization model having an associated objective function and one or more parameter values, each corresponding to one of one or more penalty constraints. The processing device determines a constrained objective function based on the objective function associated with the selected nonnegative tensor factorization model, the one or more parameter values and the one or more class labels and including the one or more penalty constraints. The processing device determines clusters for the plurality of information items by evaluating the constrained objective function. Pairwise constraints may be received in addition to or instead of the class labels.
    • 公开了使用非负张度因子分解对信息项进行聚类的方法和系统。 处理装置接收每个对应于信息项的一个或多个类标签,具有相关联的目标函数和一个或多个参数值的非负张力因子分解模型的选择,每一个对应于一个或多个惩罚约束之一。 所述处理装置基于与所选择的非负张量因子分解模型相关联的目标函数,所述一个或多个参数值和所述一个或多个类别标签并且包括所述一个或多个惩罚约束来确定约束目标函数。 处理装置通过评估约束目标函数来确定多个信息项的集群。 除了类标签之外,也可以接收成对约束。

    • Techniques for image browsing, navigating and user interface operation are described herein. An image cube, having three axes representing a medical patient's body parts, imaging technology and image date, may be displayed on a visual display. Image piles of icons or thumbnail images may be positioned within the image cube, according to the three axes. By fixing the body parts axis on a specific body part, an image plane may be selected from the image cube. The selected image plane replaces the image cube in the visual display, including only image piles of the selected body part, organized according to axes indicating imaging technology and image date. An image pile may be selected from the image plane, to replace the image plane on the visual display. Image pile operations allow the user to select from the image pile a desired image(s) for display.
    • 本文描述了用于图像浏览,导航和用户界面操作的技术。 可以在视觉显示器上显示具有表示医疗病人身体部位,成像技术和图像日期的三个轴的图像立方体。 根据三个轴,图像堆叠的图标或缩略图可能位于图像立方体内。 通过将身体部位轴固定在特定身体部位上,可以从图像立方体中选择图像平面。 所选择的图像平面替换视觉显示中的图像立方体,仅包括根据指示成像技术和图像日期的轴组织的所选身体部位的图像堆。 可以从图像平面中选择图像堆,以替换可视显示器上的图像平面。 图像桩操作允许用户从图像堆中选择所需的图像以进行显示。
