Variables

class paddle::IParameterUpdaterHook __attribute__
class IParameterUpdaterHook
#include <ParameterUpdaterHook.h>

The parameter updater hook interface.

The Parameter Updater hooks is a group of methods invoke before ParameterUpdater::updateImpl. It can modify gradient/momentum/etc before parameter optimization.

Subclassed by paddle::StaticPruningHook

Public Functions

virtual ~IParameterUpdaterHook()
virtual void update(Parameter *para) = 0

The update hook method. Invoke before ParameterUpdater::updateImpl

virtual void init(Parameter *para) = 0

The init hook method. Invoke in ParameterUpdater::init

Public Static Functions

std::shared_ptr<IParameterUpdaterHook> create(const ParameterConfig &paramConfig, int idx)

Create A ParameterUpdaterHook.

The same parameter shared the same hooks. So it returns shared_ptr.

Parameters
  • param_config -

    The parameter config.

  • idx -

    The element index of param_config.updater_hooks() array.

Protected Functions

IParameterUpdaterHook()

Ctor.
