tf_agents.bandits.policies.linalg.conjugate_gradient

Returns X such that A * X = B.

tf_agents.bandits.policies.linalg.conjugate_gradient(
    a_mat: tf_agents.typing.types.Tensor,
    b_mat: tf_agents.typing.types.Tensor,
    tol: float = 1e-10
) -> tf_agents.typing.types.Float

Implements the Conjugate Gradient method. https://en.wikipedia.org/wiki/Conjugate_gradient_method

Args
`a_mat`	a Symmetric Positive Definite matrix, represented as a `Tensor` of shape `[n, n]`.
`b_mat`	a `Tensor` of shape `[n, k]`.
`tol`	(float) desired tolerance on the residual.

Returns
`X`	`Tensor` `X` of shape `[n, k]` such that `A * X = B`.

Raises
`ValueError`	if `a_mat` is not square or `a_mat` and `b_mat` have incompatible shapes.
