Oldest Human-Made Geometric Designs Found On 60,000-Year–Old Ostrich Eggshells

“The results demonstrate that Homo sapiens during the late [Middle Stone Age] mastered precise, pre-planned patterns anchored in specific geometric affordances: orthogonality [meaning the use of right ...

Common Spatial Pattern revisited by Riemannian geometry

Abstract: This paper presents a link between the well known Common Spatial Pattern (CSP) algorithm and Riemannian geometry in the context of Brain Computer Interface (BCI). It will be shown that CSP ...
