Semi-Supervised Learning via Swapped Prediction for Communication Signal Recognition

no code implementations14 Nov 2023 Weidong Wang, Hongshu Liao, Lu Gan

Deep neural networks have been widely used in communication signal recognition and achieved remarkable performance, but this superiority typically depends on using massive examples for supervised learning, whereas training a deep neural network on small datasets with few labels generally falls into overfitting, resulting in degenerated performance.
