Graph and Symbol
ComputationGraph(API) is the basic computation model class.
All other computation model are based on this class.
A typical forward computation with
ComputationGraph like below:
let g = ComputationGraph() /// Add input and operators /// ... /// This only needs to be called before 1st forward g.forwardPrepare() let results = g.forward()
Below figure illustrates the forward process in
ComputationGraph forward computation, Serrano does not do any memory optimization.
ComputationGraph stores all inner results for each operator's output.
