Item-based sampling works, leading to functioning t-SNE. Check the same for negative edge sampling and UMAP.

There is a bug concerning the sampling. The indices returned by the WeightedRandomSampler are in terms of the value list of the sparse relation matrix. This index must be converted into the proper row and column index first, and only then can the negative sampling commence.
