凸函数的圖像上任取兩點，連成的線段必在圖像上方。 二元二次多項式函數 (,) + + 的圖像，形如開口向上的碗。. 凸函数（英文：Convex function）是指函数图形上，任意兩點連成的線段， …

In mathematics, a real-valued function is called convex if the line segment between any two distinct points on the graph of the function lies above or on the graph between the two points. …

3D Convex Splatting achieves high-quality novel view synthesis and fast rendering by representing scenes with 3D smooth convexes. In contrast, the softness of Gaussian …

Let's say we have a function $f:\Bbb R^m\to\Bbb R^n$, what does it mean for $f$ to be convex? I stumbled upon this term in article on high dimensional probability theory and I couldn't find a …

2014年2月8日 · For every face, compute the equation of the plane of support and check that all vertices* yield the same sign when plugged in the plane equation. Will take time O(F.V), for F …

Geometry of Convex Functions The link between convex sets and convex functions is via the epigraph: A function is convex if and only if its epigraph is a convex set.

In the previous couple of lectures, we’ve been focusing on the theory of convex sets. In this lecture, we shift our focus to the other important player in convex optimization, namely, convex …

2019年7月27日 · 凸包 (Convex Hull)是 计算几何 中的一个经典常用的算法。 它解决的问题在于给定空间一堆离散的点，计算包含所有点的 凸多边形。 凸是指图形内任意两点的连线都不经过 …

A function f: V → R is convex if and only if for any x ∈ dom f and any v ∈ V, the function g (t) = f (x + t v) is convex (on its domain , {t ∈ R | x + t v ∈ dom f}). In other words, f is convex if and only …
