Hello there,
this PR adds a separate class for sparsity-based optimizations and for related pre-computations to estimate sparsity. It is appended to the dynamic rewrites.
For now, the sparsity optimizers replicates the sparsity-based matrix multiplication rewrites. In the future, this can be extended to complete re-creation of the computation graph.
All the best,
David
