What did Smith report for cyclical learning rates on tested classification tasks?
Smith reported improved classification accuracy without tuning and often in fewer iterations on the tested datasets; the paper does not guarantee a specific loss-landscape escape mechanism.

During a triangular cyclical learning-rate cycle, how does the rate move between its bounds?
A triangular policy increases the rate during one half-cycle and decreases it during the other half.
