The authors have identified critical typographical errors in two equations in the paper, which are important for the reader to correctly calculate the posterior covariance matrix.
1.
Eq. (62) should be corrected asThis can be readily verified by differentiating Eq. (59) with respect to and using the fact that . Dimension analysis also provides a quick check. This equation is used for evaluating via Eq. (71).
(62)
2.
Eq. (80) should be corrected asThis can be verified by direct differentiation of Eq. (54) with respect to and , and applying Eq. (83) for derivatives involving the Rayleigh quotient. Dimension analysis also provides a quick check.
