Web26 aug. 2024 · As other answers have noted, a function is said to be convex (or "convex up"; I've never seen "concave up" before, although the meaning is obvious enough in context) if the line segment connecting any two points on its graph lies entirely above (or on) the graph between those points, and concave (or "convex down" / "concave down") if the line … Webever, their suitability for link prediction in hypergraphs is un-explored – we ﬁll this gap in this paper and propose Neural Hyperlink Predictor (NHP). NHP adapts GCNs for link pre-diction in hypergraphs. We propose two variants of NHP – NHP-U and NHP-D – for link prediction over undirected and directed hypergraphs, respectively.
