Simplicial embeddings
WebbEffective Higher-order Link Prediction and Reconstruction from Simplicial Complex Embeddings belongs to the simplicial complex K(for any σ∈Kand τ⊂σ, we also have τ∈K). This constraint makes simplicial complexes different from hypergraphs, for which there is no prescribed relation between hyper-edges. WebbUsing the Takens' embedding--a geometric representation of time-series--we construct simplicial complexes from EEG data.
