OuterProduct seems to be rather slow for large SparseVectors. Consider, for example,
```
let bar = SparseVector.init 5000 (fun i -> if i%100=0 then float i else 0.)
let mat1 = bar.OuterProduct(bar)…

My flag and skirt under sparse-mode are still slow.
The FPS is approximately 0.3~1 . I think my laptop is doing its best since it makes such a large noise.
Thus I wonder if there is an expected spe…

Hi,
I was wondering if you have any examples of recommendation systems using your code?
How can we build a recommendation model and predict using MatrixFactorization?

I want to calculate the inverse of a sparse matrix, how can I do this ?
for example
```py
vers_n=200000
ind_i = torch.Tensor(list(range(vers_n))).long().view(1,-1)
ind_j = torch.Tensor(list(ran…

We are working on to increase supports for sparse tensor. Currently we have [summarized current state of sparse tensor](https://github.com/pytorch/pytorch/issues/9674) and listed out [sparse ops to su…

Hi, In this code I get the error. Where the X_pool shape is (1024, 8).
query_idx, query_instances = learner.query(X_pool, n_instances=5)
Please let me know what is wrong here.
I used the Rank…

I (Stefan @Krastanov ) edited this issue to give some context. @Mulliken reported below a performance issue due to using a sparse initial state matrix in `timeevolution.master`. A large array of spars…

CSR/CSC matrices and others can be non-canonical in that they have unsorted or even duplicate indices for a particular row, as well as entries that have an explicit "0" entry in a cell.
While I expec…
