Protected Member Functions inherited from kjb::Abstract_dynamics
void	run (unsigned int iterations)
	Implements stochastic dynamics sampling on a set of parameters. This implementation follows the algorithm described in the 1993 Neal Paper, with leapfrog discretization and stochastic transitions weighted by the stochastic alpha parameter. This function MUST be kept protected so that only classes that inherit from this class can use it. Each of this derived class will have to provide its own public interface to this method. More...
Protected Attributes inherited from kjb::Likelihood_dynamics
kjb::Vector	etas
	The size of the step to use when computing the gradient of the energy function, in a two point estimate fashion. This varies for each parameter we are sampling over. More...
std::vector< boost::function1 < void, double > >	callbacks
	We have a callback for each parameter we are sampling over. Each of them returns a void and accepts a double. Each callback should change the model according to the sampled parameter value. More...
std::vector< boost::function0 < double > >	parameter_getters
	We have a callback for each parameter we are sampling over. Each of them returns a double. Each callback should get the parameter value to initialize the sampling. More...
