Variable.backward

grain autograd Variable

computes gradients of creator variables w.r.t. the arg grad

  1. void backward(UntypedVariable* grad, size_t pos)
    struct Variable(T, size_t dim, alias Storage = HostStorage, SliceKind kind = Contiguous)
    void
    backward
    (
    UntypedVariable* grad
    ,
    size_t pos = 0
    )
