Matrix sketching算法
Web8 dec. 2024 · Recently, in statistics and machine learning, the notion of Randomization in Numerical Linear Algebra (RandNLA) has not only evolved as a vital new tool to design … WebThis paper proposes a new low-rank tensor approximation sketch algorithm that only passes through the original tensor once during calculation. This algorithm also provides a theoretical approximation guarantee, as well as computational speed comparable to existing non-streaming algorithms. Simulations as well as experiments on real weather and ...
