Types

type Model

type Model struct {
	nn.BaseModel
	WPart    nn.Param `spago:"type:weights"`
	WPartRec nn.Param `spago:"type:weights"`
	BPart    nn.Param `spago:"type:biases"`

	WResRec  nn.Param `spago:"type:weights"`
	BRes     nn.Param `spago:"type:biases"`
	WCand    nn.Param `spago:"type:weights"`
	WCandRec nn.Param `spago:"type:weights"`
	BCand    nn.Param `spago:"type:biases"`
	States   []*State `spago:"scope:processor"`
}

Model contains the serializable parameters.

func New

func New(in, out int) *Model

New returns a new model with parameters initialized to zeros.

func (*Model) Forward

func (m *Model) Forward(xs ...ag.Node) []ag.Node

Forward performs the forward step for each input node and returns the result.

func (*Model) LastState

func (m *Model) LastState() *State

LastState returns the last state of the recurrent network. It returns nil if there are no states.

func (*Model) SetInitialState

func (m *Model) SetInitialState(state *State)

SetInitialState sets the initial state of the recurrent network. It panics if one or more states are already present.

type State

type State struct {
	R ag.Node
	P ag.Node
	C ag.Node
	Y ag.Node
}

State represent a state of the GRU recurrent network.
