Member Function Documentation

reset()

void MiniDNN::AdaGrad::reset ( )

inlinevirtual

Reset the optimizer to clear all historical information

Reimplemented from MiniDNN::Optimizer.

Definition at line 35 of file AdaGrad.h.

update()

void MiniDNN::AdaGrad::update ( ConstAlignedMapVec &  dvec, AlignedMapVec &  vec  )

inlinevirtual

Update the parameter vector using its gradient

It is assumed that the memory addresses of dvec and vec do not change during the training process. This is used to implement optimization algorithms that have "memories". See the AdaGrad algorithm for an example.

Parameters

dvec	The gradient of the parameter. Read-only
vec	On entering, the current parameter vector. On exit, the updated parameters.

Implements MiniDNN::Optimizer.
