Based on the discussion in Section 2.1. ≤ 𝛼𝑡 exp,10ppd where 𝛼 = 60%, 70%, …, or 100%, and 𝑡 exp,10ppd is the time for the 10 ppd experiment. For the ALC, the integral in ( ) was computed with the trapezoidal rule on the log-spaced range from 2𝜋 × 10 -2 to 2𝜋 × 10 6 rad/s with 10 ppd. Moreover, we updated the vector of hyperparameters only at the 30 th iteration.
