pyhgf.typing.typing.AdjacencyLists

class pyhgf.typing.typing.AdjacencyLists(node_type, value_parents, volatility_parents, value_children, volatility_children, coupling_fn)

Indexes to a node’s value and volatility parents.

The variable node_type encode the type of state node: * 0: input node. * 1: binary state node. * 2: continuous state node. * 3: exponential family state node - univariate Gaussian distribution with unknown

mean and unknown variance.

• 4: Dirichlet Process state node.

The variable coupling_fn list the coupling functions between this nodes and the children nodes. If None is provided, a linear coupling is assumed.

Parameters:

• node_type (int) – The type of the state node (see the codes listed above).

• value_parents (tuple | None) – Indexes to the value parents of the node, or None when the node has no value parent.

• volatility_parents (tuple | None) – Indexes to the volatility parents of the node, or None when the node has no volatility parent.

• value_children (tuple | None) – Indexes to the value children of the node, or None when the node has no value child.

• volatility_children (tuple | None) – Indexes to the volatility children of the node, or None when the node has no volatility child.

• coupling_fn (tuple[Callable | None, ...]) – The coupling functions between the node and its children. If None is provided, a linear coupling is assumed.
