  It is easy for the electroencephalogram (EEG) signal to be incomplete due to
packet loss, electrode falling off, etc. This paper proposed a Cascade
Transformer architecture and a loss weighting method for the single-channel EEG
completion, which reduced the Normalized Root Mean Square Error (NRMSE) by 2.8%
and 8.5%, respectively. With the percentage of the missing points ranging from
1% to 50%, the proposed method achieved a NRMSE from 0.026 to 0.063, which
aligned with the state-of-the-art multi-channel completion solution. The
proposed work shows it's feasible to perform the EEG completion with only
single-channel EEG.
