WebJan 24, 2024 · In this work, by applying the manifold learning method, a manifold regularization term is added to the objective function of the triple decomposition. Since … In topology, a branch of mathematics, a manifold M may be decomposed or split by writing M as a combination of smaller pieces. When doing so, one must specify both what those pieces are and how they are put together to form M. Manifold decomposition works in two directions: one can start with the smaller pieces and build up a manifold, or start with a large manifold and decompose it. The latter has proven a very useful …

WebLoop decomposition of manifolds - Ruizhi Huang, BIMSA (2024-03-07) The classification of manifolds in various categories is a classical problem in topology. It has been widely investigated by applying techniques from geometric topology in the last century. However, the known results tell us very little information about the homotopy of manifolds.
