CVM Operator.
We assume that input is a embedding vector with cvm_feature(show and click), which shape is [N * D] (D is 2(cvm_feature) + embedding dim, N is batch_size)
if use_cvm is True, we will log(cvm_feature), and output shape is [N * D].
if use_cvm is False, we will remove cvm_feature from input, and output shape is [N * (D - 2)].
