Learning with Retrospection [article]

Xiang Deng, Zhongfei Zhang
2020 arXiv   pre-print
In this paper, we propose learning with retrospection (LWR) which makes use of the learned information in the past epochs to guide the subsequent training.  ...  LWR is a simple yet effective training framework to improve accuracies, calibration, and robustness of DNNs without introducing any additional network parameters or inference cost, only with a negligible  ...  Then we make further derivations of the standard process to show how to train DNNs with retrospection.  ...
