Hi, can you provide a demo to show how to use sparse training ? And according to Paddle's documentation , there are four kinds of input : dense_vector , sparse_binary_verctor, sparse_float_vector and integer, do you take sparse_int_vector into account ? I find paddle implement sparse matrix multiplication wihtout calling MKL library. I want to konw wherther the implementation of sparse matrix multiplication in paddle is faster than calling MKL library ?
