There is a branch of mathematics called `combinatorial geometry' which deals with properties of certain special sets of certain special elements. Often these elements are called `points' and these sets are called `lines' and special requirements (called `axioms') are introduced which must be met by these points and lines.

Discrete geometry and combinatorial geometry are branches of geometry that study combinatorial properties and constructive methods of discrete geometric objects. Most questions in discrete geometry involve finite or discrete sets of basic geometric objects, such as points, lines, planes, circles, spheres, polygons, and so forth.

To summarize, the most original of our contributions is the inference of support relations in complex indoor scenes. We incorporate geometric structure inferred from depth, object properties encoded in our structural classes, and data-driven scene priors, and our approach is robust to clutter, stacked objects, and invisible supporting surfaces.
Combinatorial geometry this is a difficult topic to define precisely without including all of discrete and computational geometry. What i mean by combinatorial geometry consists of problems in which one starts with a geometric figure (say a polytope) but then considers abstract incidence properties of it rather than its metric properties.

Frequentist inference is aimed at given procedures with frequency guarantees. Bayesian inference is about stating and manipulating subjective beliefs. In general, these are differ-ent, a lot of confusion would be avoided if we used f(c) to denote frequency probablity and b(c) to denote degree-of-belief probability.

Geometric group theory acquired a distinct identity in the late 1980s but many of its principal ideas have their roots in the end of the nineteenth century. At that time, low-dimensional topology and combinatorial group theory emerged entwined. Roughly speaking, combinatorial group theory is the study of groups defined in terms of presen-.

In probability theory and statistics, the hypergeometric distribution is a discrete probability distribution that describes the probability of successes (random draws for which the object drawn has a specified feature) in draws, without replacement, from a finite population of size that contains exactly objects with that feature, wherein each draw is either a success or a failure.

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying smoothly, the objects studied in discrete mathematics – such as integers, graphs, and statements in logic – do not vary smoothly in this way, but have distinct, separated values.
Deep learning-based object detection and instance segmentation have achieved unprecedented progress. In this paper, we propose complete-iou (ciou) loss and cluster-nms for enhancing geometric factors in both bounding box regression and non-maximum suppression (nms), leading to notable gains of average precision (ap) and average recall (ar), without the sacrifice of inference efficiency.
There are many important topics in the statistical study of likelihood inference that should belong to “likelihood geometry” but are not covered in this article.
