Abstract: This work introduces a novel dissimilarity measure between two convex cones, based on the max-min angle between them. We demonstrate that this measure is closely related to the Pompeiu-Hausdorff distance, a well-established metric for comparing compact sets. Furthermore, we examine cone configurations where the measure admits simplified or analytic forms. For the specific case of polyhedral cones, a nonconvex cutting-plane method is deployed to compute, at least approximately, the measure between them. Our approach builds on a tailored version of Kelley's cutting-plane algorithm, which involves solving a challenging master program per iteration. When this master program is solved locally, our method yields an angle that satisfies certain necessary optimality conditions of the underlying nonconvex optimization problem yielding the dissimilarity measure between the cones. As an application of the proposed mathematical and algorithmic framework, we address the image-set classification task under limited data conditions, a task that falls within the scope of the \emph{Few-Shot Learning} paradigm. In this context, image sets belonging to the same class are modeled as polyhedral cones, and our dissimilarity measure proves useful for understanding whether two image sets belong to the same class.

Ilford Pan 100 (FF) English Alt Text: A black-and-white photo of a brick wall with a paper sign attached. The sign, written in Chinese, reads “Paint not dry. Please do not approach.” It’s placed near a doorway, with part of the interior visible, including a large container. The scene suggests a cautionary moment in a residential or public space, with the sign warning passersby to avoid contact with freshly painted surfaces. 中文替代文字： 这是一张黑白照片，展示了一面砖墙，墙上贴有一张纸质告示。告示用中文写着：“油漆未干，请勿靠近。”告示位于一扇门附近，门内可…
Ilford Pan 100 (FF) English Alt Text: A black-and-white image showing three large containers. The left container is filled with used disposable cameras, film canisters, and plastic packaging. The middle container is sealed with a lid. The right container is open and contains a liquid substance, possibly water or chemicals, with residue on its inner walls. The scene appears to document the disposal or recycling of analog photography materials. 中文替代文字： 这是一张黑白图像，展示了三个大型容器。左侧容器中装有使用过的一次性相机、胶卷罐和塑料…
Ilford Pan 100 (FF) English Alt Text: A black-and-white photo of a narrow alleyway with brick walls on both sides. The alley is paved with tiles and leads to a brightly lit exit in the distance. Several bicycles are parked along the walls, casting shadows on the ground. The lighting creates a dramatic contrast between the dark interior and the bright light at the end, emphasizing depth and texture. The scene feels quiet and urban, with a sense of solitude and anticipation. 中文替代文字： 这是一张黑白照片，展示…
Ilford Pan 100 (FF) English Alt Text: A black-and-white urban street scene. In the foreground, a large rectangular object with horizontal stripes sits on a brick-paved sidewalk. Behind it stands a tree partially obscuring a circular traffic sign. The background shows a busy street with moving vehicles, pedestrians walking and crossing, and tall buildings lining the road. The photo captures a moment of everyday city life with a mix of natural and man-made elements. 中文替代文字： 这是一张黑白城市街景照片。前景中，一个带…

Trump -- openly fearful that a Congress controlled by Democrats could investigate him, impeach him and stymie his agenda

Many of these endeavors go far beyond typical political persuasion,
