This work aims to study sparsity in widely-used tensor networks by introducing constraints, regularization, dictionary, and/or domain knowledge for better data compression, faster computation, lower memory storage, along with better interpretability by: 1) Proposing memory hierarchy and microarchitecture-aware representations and effective yet efficient data (re-)arranging; 2) Designing memory hierarchy-aware and balanced algorithm with smart page arrangement; 3) Erasing the curse of dimensionality through memoization and intelligent data allocation; 4) Exploring specialized architecture on GPU and FPGA. We will accelerate six application scenarios by leveraging the scalable and highly optimized sparse tensor network on distributed heterogeneous systems.
