Typedefs

using syten::STensorImpl::Autodiff::AdjointEvaluator = std::function< STensor(ComputeNode &node, Size input_number, STensorId const result_id)>
 Type of the input adjoint evaluator which can access the adjoints of all output values as well as the stored input and output tensors of the node to evaluate an output adjoint of an upstream node. More...
 
using syten::AutodiffRescale = YesNo< struct _autodiffrescale >
 Whether or not to rescale the output adjoints during autodifferentiation. More...
 
using syten::STensorImpl::Autodiff::ComputeNodePtr = std::shared_ptr< ComputeNode >
 Type of a shared pointer to a compute node. More...
 
using syten::STensorImpl::Autodiff::ComputeNodeWPtr = std::weak_ptr< ComputeNode >
 Type of a weak pointer to a compute node, used for the "downstream" direction. More...
 
using syten::STensorImpl::Autodiff::STensorId = std::uint64_t
 Randomly-generated ID of an STensor, to be used during automatic differentiation. More...
