SpletThis work exploits the fact that the random matrix requires less precision, and develops a highly optimized matrix multiplication between FP32 and FP16 matrices -- SHGEMM (Single and Half-precision GEMM) -- on Tensor Cores, where therandom matrix is stored in FP16. Random projection can reduce the dimension of data while capturing its structure and is … Splet14. jun. 2024 · The major difference is that a matrix has only 2 indices (can also be represented as M [n] [m]) whereas tensors can have any indices ( T [i1] [i2] [i3]….) even …
