Web30 de jul. de 2024 · In this work, we choose a TN with a hierarchical tree structure, called tree TN (TTN). Compared with MPS, TTN is more similar to the deep neural network, since both possess a hierarchical structure. (figure A1 (d)) shows a TTN formed by third-order tensors. This TTN consists of several layers. Web5 de jun. de 2014 · One of the main problems associated with surface approximation by B-splines is the adequate selection of the number and location of the knots, as well as the solution of the system of equations generated by tensor product spline surfaces. In this work, we use a hierarchical genetic algorithm (HGA) to tackle the B-spline surface …
