Functions

func AddPFC

func AddPFC(nt *leabra.Network, name string, nPoolsY, nPoolsX, nNeurY, nNeurX int, pulvLay bool) (super, ct, maint, out, pulv emer.Layer)

AddPFC adds a PFC system including SuperLayer, CT with CTCtxtPrjn, MaintLayer, and OutLayer which is gated by BG. Name is set to "PFC" if empty. Other layers have appropriate suffixes. Optionally creates a TRC Pulvinar for Super. Standard Deep CTCtxtPrjn PoolOneToOne Super -> CT projection, and 1to1 projections Super -> Maint and Maint -> Out class PFCFixed are created by default. CT is placed Behind Super, then Out and Maint, and Pulvinar behind CT if created.

Types

type MaintLayer

type MaintLayer struct {
	glong.Layer
	PulseClear PulseClearParams      `desc:"parameters for the synchronous pulse of activation / inhibition that clears NMDA maintenance."`
	InterInhib interinhib.InterInhib `desc:"inhibition from output layer"`
}

///////////////////////////////////////////////////////////////////////// MaintLayer is a layer with NMDA channels that supports active maintenance in frontal cortex, via NMDA channels (in an NMDAMaintPrjn).

func AddMaintLayer

func AddMaintLayer(nt *leabra.Network, name string, nPoolsY, nPoolsX, nNeurY, nNeurX int) *MaintLayer

AddMaintLayer adds a MaintLayer using 4D shape with pools, and lateral NMDAMaint PoolOneToOne connectivity.

func (*MaintLayer) Defaults

func (ly *MaintLayer) Defaults()

func (*MaintLayer) InhibFmGeAct

func (ly *MaintLayer) InhibFmGeAct(ltime *leabra.Time)

InhibFmGeAct computes inhibition Gi from Ge and Act averages within relevant Pools

func (*MaintLayer) InterInhibMaxAct

func (ly *MaintLayer) InterInhibMaxAct(ltime *leabra.Time) float32

InterInhibMaxAct returns the AlphaMax activation for source layers

func (*MaintLayer) PulseClearNMDA

func (ly *MaintLayer) PulseClearNMDA()

PulseClearNMDA simulates a synchronous pulse of activation that clears the NMDA and puts the layer into a refractory state by activating the GABAB currents.

type Network

type Network struct {
	deep.Network
}

agate.Network has methods for configuring specialized AGate network components for Attentional & adaptive Gating of Action and Thought for Executive function.

func (*Network) AddBG

func (nt *Network) AddBG(prefix string, nPoolsY, nPoolsX, nNeurY, nNeurX int, space float32) (mtxGo, mtxNo, cin, gpeOut, gpeIn, gpeTA, stnp, stns, gpi, vthal leabra.LeabraLayer)

AddBG adds MtxGo, No, CIN, GPeOut, GPeIn, GPeTA, STNp, STNs, GPi, and VThal layers, with given optional prefix. Assumes that a 4D structure will be used, with Pools representing separable gating domains. Only Matrix has more than 1 unit per Pool by default. Appropriate PoolOneToOne connections are made between layers, using standard styles. space is the spacing between layers (2 typical)

func (*Network) AddPFC

func (nt *Network) AddPFC(name string, nPoolsY, nPoolsX, nNeurY, nNeurX int, pulvLay bool) (super, ct, maint, out, pulv emer.Layer)

AddPFC adds a PFC system including SuperLayer, CT with CTCtxtPrjn, MaintLayer, and OutLayer which is gated by BG. Name is set to "PFC" if empty. Other layers have appropriate suffixes. Optionally creates a TRC Pulvinar for Super. CT is placed Behind Super, then Out and Maint, and Pulvinar behind CT if created.

func (*Network) ConnectToMatrix

func (nt *Network) ConnectToMatrix(send, recv emer.Layer, pat prjn.Pattern) emer.Prjn

ConnectToMatrix adds a MatrixTracePrjn from given sending layer to a matrix layer
