Sparse linear algebra matrix solver doesn't work with complex numbers on a GPU (solver not available at all on the CPU) Sample Code: import torch from torch import sparse n = 10 A = torch.rand(n, n).type(torch.complex128).to_sparse_csr().cuda() b = torch.rand(n).type(torch.com...

Givenand, we define the index sets of zero components ofxand active inequality constraints at, respectively. For an arbitrary vectorx, we writefor the corresponding diagonal matrix, whose diagonal entri...

Sparsity: We never use our Wasserstein barycenter solver with more than n data distributions at a time. Full adaptivity: The support of the vector of weights ωNn,EE(x) is optimized with respect to x. Instead of relying on a unique simplex Yn as in [12, 32], our regression method may...
To apply PCA to sparse data, we can use the scikit-learn library in Python. The library provides a PCA class that we can use to fit a PCA model to the data and transform it into lower-dimensional space. In the first section of the following code, we create a dataset as we did in...
this is checked by invocations to a SAT solver. The effectiveness of this procedure hinges on the ability of the SAT solver to deal with XOR constraints, which in turn crucially depends on the length of such constraints. We study to what extent one can employ sparse, hence short, constraints...
