WebbVariational auto-encoders (VAEs) are deep generative models used for unsupervised learning, however their standard version is not topology-aware in practice since the data topology may not be taken into consideration. In this paper, we propose two different approaches with the aim to preserve the topological structure between the input space … WebbThe drawing routines in simplicial are based around the use of the simplicial.Embedding class, which specifies the embedding of a simplicial complex into a space. Various sub-classes of simplicial.Embedding provide different positionings, which the drawing sub-system then renders.
