Multigroup Thermal Radiation Transport with Tensor Trains
Aditya S. Deshpande, Patrick D. Mullen, Alex A. Gorodetsky +4
We investigate the application of tensor-train (TT) algorithms to multigroup thermal radiation transport (i.e., photon radiation transport). The TT framework enables simulations at…

Hierarchical Search of Tree Tensor Networks for High-Dimensional Data
Zheng Guo, Aditya Deshpande, Xinyu Wang +2
Tensor network methods provide a scalable solution to represent high-dimensional data. However, their efficacy is often limited by static, expert-defined structures that fail to ad…

Thermal Radiation Transport with Tensor Trains
Alex A. Gorodetsky, Patrick D. Mullen, Aditya Deshpande +4
We present a novel tensor network algorithm to solve the time-dependent, gray thermal radiation transport equation. The method invokes a tensor train (TT) decomposition for the spe…
