apeforest commented on issue #14619: [Discussion] 1.5.0 Roadmap URL: https://github.com/apache/incubator-mxnet/issues/14619#issuecomment-503645009 @mouryarishik We've already have a few operators to support higher order gradient: ``` elemwise_mul, log, log10, relu, FullyConnected, sin, cos, exp ``` However, due to the current design of NNVM, the graph data structure to model the computation graph, the support of higher order gradient in operators has to be implemented one by one (good news is that moving to NNVM 2.0 in the near future higher order gradient in operators will be supported automatically by NNVM). In the meantime before NNVM is upgraded to 2.0, we plan to support higher order gradient in a limited number of operators. It would be great if you could identify a set of operators that are used in your model and require higher order gradient support. We will prioritize implementation for those operators. Thanks for your continuous support and passion for MXNet.
