pyhgf.updates.vectorised.continuous.VolatilityChild

class pyhgf.updates.vectorised.continuous.VolatilityChild(state, kappa, params)

The volatility child of a continuous layer, as seen by its posterior update.

Parameters:

• state (pyhgf.typing.vectorised.LayerState) – The child layer’s state, already carrying its posterior and volatility_prediction_error.

• kappa (jax.Array) – The volatility-coupling matrix, shape (n_child, n_parent).

• params (pyhgf.typing.vectorised.LayerParams) – The child layer’s parameters (tonic_volatility is read by the eHGF and unbounded updates).
