Detailed Description
Simulate a new warmstarted run/restart once a number of epochs are performed.
Importantly, the restarts are not performed from scratch but emulated by increasing the step size while the old step size value of as an initial parameter.

◆ CyclicalDecay()

inline 
Construct the CyclicalDecay technique a restart method, where the step size decays after each batch and peridically resets to its initial value.
 Parameters

epochRestart Initial epoch where decay is applied. multFactor Factor to increase the number of epochs before a restart. stepSize Initial step size for each restart. batchSize Size of each minibatch. numFunctions The number of separable functions (the number of predictor points).
