Jitter: Random Jittering Loss Function [PDF]
2021 International Joint Conference on Neural Networks (IJCNN), 2021 Regularization plays a vital role in machine learning optimization. One novel regularization method called flooding makes the training loss fluctuate around the flooding level. It intends to make the model continue to random walk until it comes to a flat loss landscape to enhance generalization.

Binary phase detector gain in bang-bang phase-locked loops with DCO jitter [PDF]
, 2010 Bang-bang phase-locked loops (BBPLLs) are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). In the presence of jitter, the nonlinear loop is typically analyzed by linearizing the BPD and applying linear ...
