   Hi @joddiy,
   
   Would we be considering only 2 dimensions for the scatter_elements operation?
   For backwards operation with scatter_elements can we store the indexes we process during
the forward pass, this can help us reducing the time complexity for the operation?
   Also for implementing the advanced indexing operation, we can implement it as a suboptimal
operation for processing the index as a list of tuples and further indexing only based on
those list of tuples? This can save complexity of iterating over dimension elements multiple
times
   
   Thanks and Regards,
   Shashank Nigam
