- The user API looks like the following:
/*! * \brief Eliminate common subexpressions among \p in_args and between them and \p output . * * \param output The output tensor. * \param input_grads The gradients of input tensors. */ std::pair<Tensor, std::vector<Tensor> > CSE(const Tensor& output, const std::vector<Tensor>& input_grads); - The tensor expression tree does not provide extra information. It is just an useful data structure for comparison purposes.
