frequency, as detailed in this paper (https://arxiv.org/abs/1506.01186).
    The amplitude of the cycle can be scaled on a per-iteration or
    per-cycle basis.
    This class has three built-in policies, as put forth in the paper.
    &#34;triangular&#34;:
        A basic triangular cycle w/ no amplitude scaling.
    &#34;triangular2&#34;:
        A basic triangular cycle that scales initial amplitude by half each cycle.
    &#34;exp_range&#34;:
        A cycle that scales initial amplitude by gamma**(cycl
