connect: Project & Gate

In brain-r/brain: Neural Network

Description

Project or gate layers and neurons.

Usage

project(brain, from, to, name = NULL)

gate_types(gate)

gate(brain, from, to, type = NULL)

Arguments

brain	An object of class brain as returned by brain.
from, to	Name of neurons or layers to project or gate.
name	If not NULL then the projection is stored internally and can be used later on, see "gate" example.
gate	The type of gate required, see gates
type	An object of class gate as returned by gate_types or NULL.

Gates

• input: If layer C is gating connections between layer A and B, all the neurons from C gate all the input connections to B.

• output: If layer C is gating connections between layer A and B, all the neurons from C gate all the output connections from A.

• one2one: If layer C is gating connections between layer A and B, each neuron from C gates one connection from A to B. This is useful for gating self-connected layers. To use this kind of gateType, A, B and C must be the same size.

network to create a network from the connected layers.

Examples

# project
brain() %>%
  layer("input", 2) %>%
  layer("hidden", 3) %>%
  layer("output", 1) %>%
  project("input", "hidden") %>%
  project("hidden", "output")

# gate
brain() %>%
  layer("A", 5) %>%
  layer("B", 3) %>%
  project("A", "B", "connection") %>%
  layer("C", 4) %>%
  gate(
    "C",
    "connection",
    gate_types("input")
  )
