Functions

func NetVarsList added in v1.0.0 

func NetVarsList(net emer.Network, layEven bool) []string

NetVarsList returns the list of layer and prjn variables for given network. layEven ensures that the number of layer variables is an even number if true (used for display but not storage).

Types

type LayData added in v1.0.0 

type LayData struct {
	LayName string    `desc:"the layer name"`
	NUnits  int       `desc:"cached number of units"`
	Data    []float32 `desc:"the full data, Ring.Max * len(Vars) * NUnits in that order"`
