Every finite convex geometry can be embedded into a convex geometry of finitely many points in an n-dimensional space equipped with a convex hull operator, by the result of K. Kashiwabara, M.Nakamura and Y.Okamoto (2005). Allowing circles rather than points, as was suggested by G.Cz茅dli...

State representation learning (SRL) is a particular case of feature learning in which the features to learn are low dimensional, evolve through time, and are influenced by actions or interactions.

We study the properties of Schnyder’s realizers and canonical ordering trees of plane graphs. Based on these newly discovered properties, we obtain compact drawings of two styles for any plane graph G with n vertices. First we show that G has a visibili
英文: Algebra is but written geometry and geometry is but figured algebra.中文: 代数不过是书写的几何,而几何不过是图形的代数。英文: In the Mathematics Test, three subscores are based on six content areas: pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry, ...
By the way, when most people see diagrams such as figure 1, they are tempted to call it the “geometric interpretation” of a partial derivative. Technically, though, that’s not the right name, because if you don’t have a metric, you don’t have a geometry. Properly speaking, what ...
英文: Similar to a non-generic type, the compiled representation of a generic type is intermediate language (IL) instructions and metadata.中文: 和非泛型类似,泛型被编译后表示成中间代码指令和元数据。英文: Algebra is but written geometry and geometry is but figured algebra.中文: 代数不过是书写的...
Landmark-Based Registration Using Features Identified Through Differential Geometry Recognition Step Choosing a frame of the second structure (the scene) as the basis, we compute the invariant representation and retrieve, thanks to the hash table, what are the compatible model frame couples. If the ...
Three-dimensional (3D) building models with unambiguous roof plane geometry parameters, roof structure units, and linked topology are essential data for many applications related to human activities in urban environments. The task of 3D reconstruction from point clouds is still in the phase of develop...
