In the process of studying “Imaging Time-Series to Improve Classification and Imputation”, I had a question, that is, how to reconstruct the original time series from the obtained Gram sum/difference field (GASF/GADF)? That is, the inverse transformation of time series to image transformation. For the process of converting time series to GASF/GADF, refer to this […]

CUDA–cublas–inverse of matrix (0)
There are many ways to use CUDA to solve the inverse of a matrix. You can also write your own kernel function to implement it. I checked the CSDN Cublas’s method for solving matrix inverses, but the author’s writing is rather cumbersome, and other people who watch and learn will find it difficult to understand. […]
