- Abstract: Declarative memory has been studied for its relationship with remembering
daily life experiences. Previous studies reported changes in power spectra
during encoding phase related to behavioral performance, however decoding phase
still needs to be explored. This study investigates neural oscillations changes
related to memory process. Participants were asked to perform a memory task for
encoding and decoding phase while EEG signals were recorded. Results showed
that for encoding phase, there was a significant decrease of power in low beta,
high beta bands over fronto-central area and a decrease in low beta, high beta
and gamma bands over left temporal area related to successful subsequent memory
effects. For decoding phase, only significant decreases of alpha power were
observed over fronto-central area. This finding showed relevance of beta and
alpha band for encoding and decoding phase of a memory task respectively.

Convolutional Neural Networks (CNNs) have demonstrated superiority in learning patterns, but are sensitive to label noises and may overfit noisy labels during training.
The early stopping strategy averts updating CNNs during the early training phase and is widely employed in the presence of noisy labels.
Our proposed Phase-AmplituDe DisentangLed Early Stopping (PADDLES) method is shown to be effective on both synthetic and real-world label-noise datasets.
