InnerTest

class cockpit.quantities.InnerTest(track_schedule, verbose=False)

Quantitiy Class for tracking the result of the inner product test.

Note: Inner Product test as proposed in

• Bollapragada, R., Byrd, R., & Nocedal, J., Adaptive Sampling Strategies for Stochastic Optimization (2017). https://arxiv.org/abs/1710.11258

Initialization sets the tracking schedule & creates the output dict.

Parameters

• track_schedule (callable) – Function that maps the global_step to a boolean, which determines if the quantity should be computed.

• verbose (bool, optional) – Turns on verbose mode. Defaults to False.
