Data sparsity is one of the challenges for low-resource language pairs in Neural Machine Translation (NMT). Previous works have presented different approaches data augmentation, but they mostly require additional resources and obtain low-quality dummy issue. This paper proposes a simple effective novel generating synthetic bilingual without using external as previous approaches. Moreover, some recently shown that multilingual translation or transfer learning can boost quality situations....

The translation quality of machine systems depends on the parallel corpus used for training, in particular quantity and corpus.However, building a high-quality large-scale is complex expensive, particularly specific domain corpus.Therefore, data augmentation techniques are widely translation.The input back-translation method monolingual text, which available from many sources, therefore this can be easily effectively implemented to generate synthetic data.In practice, texts collected...

Summary In this article, we exploit the huge advantages of full‐duplex (FD) transmission, nonorthogonal multiple access (NOMA) technique, unmanned aerial vehicle (UAV), and millimeter‐wave (mmWave) communications in an Internet things (IoT) sensor network. Specifically, UAV operates as a FD amplify‐and‐forward (AF) relay to aid between IoT NOMA users. Moreover, FD‐UAV (FDU) adopts both fixed variable gains. We obtain exact expressions outage probability (OP) throughput IoT‐FDU‐NOMA‐mmWave...
