I can see that PyArrow has an object called SparseCOOTensor. Is it possible to convert it into a Sparse CSR/CSC Matrix or do I need to write a custom function to do that? Looking for something similar to the SciPy library sparse matrix conversions....
matrix factorisation (NMF) over catalogues of single nucleotide variants (SNVs) and other mutation types1,2,3,4,5,6,7,8. So far, mutational signature analysis has provided more than 50 different single base substitution patterns, indicative of a range of endogenous mutational processes, as ...

Tensor analytics lays the mathematical basis for the prosperous promotion of multiway signal processing. To increase computing throughput, mainstream processors transform tensor convolutions into matrix multiplications to enhance the parallelism of computing. However, such order-reducing transformation produces...
张量是一种多线性函数,用于表示矢量、标量和其他张量之间的线性关系,其在n维空间内有n^r个分量,每个分量都是坐标的函数。张量在坐标变换时也会按照某些规则作线性变换,是一种特殊的数据结构,在MindSpore网络运算中起着重要作用。 %%capture captured_output # 实验环境已经预装了mindspore==2.2.14,如需更换mindspore版...
random((100, 5), density=0.08) # creates COO random matrix X = sparse.asarray(X, format="csc") # converts to CSC format X_X = sparse.permute_dims(X, (1, 0)) @ X # for me locally it densifies as the result is: SwizzleArray(Tensor(Dense{Int64}(Dense{Int64}(Element{0.0, ...
This PR adds a universalSparseTensorclass totorch-sparse. Due to lacking sparse matrix support in PyTorch, I decided to build my own class which allows to be easily extendable for all kind of use-cases. It builds upon the idea of providing fast conversions between COO, CSR and CSC formats...
