Another way to approach the linear combination is to look at it geometrically. This is where the idea of barycentric coordinates can help. A barycentric coordinate system describes the location of a point as the weighted sum of the regular coordinates of the vertices forming a simplex. In other words, it describes a linear combination with respect to a set of points, where in -dimensional space.
Influencers have had a bad time of it at restaurants recently. There they are, just trying to record a quick video and take a few pictures of their lunch, and restaurateur Jeremy King (of the Ivy and the Wolseley in London) goes and writes an article saying they’re ruining the dining experience of “bona fide guests” – something he says staff are “desperately trying to stop”.
