node

Represents a node in a subsystem. Each node has a unique index, its position in the network’s list of nodes.

class pyphi.node.Node(subsystem, index, label=None)

A node in a subsystem.

subsystem

Subsystem – The subsystem the node belongs to.

index

int – The node’s index in the network.

network

Network – The network the node belongs to.

label

str – An optional label for the node.

state

int – The state of this node.

get_marbl(normalize=True)

Generate a Marbl for this node TPM.

input_indices

The indices of nodes which connect to this node.

output_indices

The indices of nodes that this node connects to.

inputs

The set of nodes with connections to this node.

outputs

The set of nodes this node has connections to.

marbl

The normalized representation of this node’s Markov blanket, conditioned on the fixed state of boundary-condition nodes in the current timestep.

raw_marbl

The un-normalized representation of this node’s Markov blanket, conditioned on the fixed state of boundary-condition nodes in the current timestep.

__eq__(other)

Return whether this node equals the other object.

Two nodes are equal if they belong to the same subsystem and have the same index (their TPMs must be the same in that case, so this method doesn’t need to check TPM equality).

Labels are for display only, so two equal nodes may have different labels.
