interinhib

README

Package interinhib provides inter-layer inhibition params, which can be added to Layer types.

Note: it is better to use direct inhibitory projections -- try that first before using this!

Note: the following has not been updated from Leabra version to axon:

Call at the start of the Layer InhibFmGeAct method like this:

// InhibFmGeAct computes inhibition Gi from Ge and Act averages within relevant Pools
func (ly *Layer) InhibFmGeAct(lctxt *Context) {
	lpl := &ly.Pools[0]
	ly.Params.Inhib.Layer.Inhib(&lpl.Inhib)
	ly.InterInhib.Inhib(&ly.Layer) // does inter-layer inhibition
	ly.PoolInhibFmGeAct(ltime)
}

Overview

Package interinhib provides inter-layer inhibition params, which can be added to Layer types. Call at the start of the Layer InhibFmGeAct method like this: // InhibFmGeAct computes inhibition Gi from Ge and Act averages within relevant Pools

func (ly *Layer) InhibFmGeAct(lctxt *Context) {
	lpl := &ly.Pools[0]
	ly.Params.Inhib.Layer.Inhib(&lpl.Inhib)
	ly.InterInhib.Inhib(&ly.Layer) // does inter-layer inhibition
	ly.PoolInhibFmGeAct(ltime)
}

Types

type InterInhib

type InterInhib struct {

	// layers to receive inhibition from
	Lays emer.LayNames `desc:"layers to receive inhibition from"`

	// multiplier on Gi from other layers
	Gi float32 `desc:"multiplier on Gi from other layers"`

	// add inhibition -- otherwise Max
	Add bool `desc:"add inhibition -- otherwise Max"`
}

InterInhib specifies inhibition between layers, where the receiving layer either does a Max or Add of portion of inhibition from other layer(s).

func (*InterInhib) Defaults

func (il *InterInhib) Defaults()

func (*InterInhib) Inhib

func (il *InterInhib) Inhib(ly *axon.Layer)

Inhib updates layer inhibition based on other layer inhibition

func (*InterInhib) OtherGi

func (il *InterInhib) OtherGi(net emer.Network) float32

OtherGi returns either the Sum (for Add) or Max of other layer Gi values. These are the raw values, not multiplied by Gi factor.
