Gaussian elimination and LU decomposition To reduce the operation count, we can just ignore the subdiagonal WebA common assumption is that nonlinear reservoirs can outperform linear reservoirs28 . Optimizing the hyperparame- ters of a reservoir computer is often done, but optimizing the connections between the RC nodes is more difficult due to the high-dimensional parameter space. The standard recipe is to use random matrices.
