- Abstract: Pile-up signals are frequently produced in experimental physics. They create
inaccurate physics data with high uncertainty and cause various problems.
Therefore, the correction to pile-up signals is crucially required. In this
study, we implemented a deep learning method to restore the original signals
from the pile-up signals. We showed that a deep learning model could accurately
reconstruct the original signal waveforms from the pile-up waveforms. By
substituting the pile-up signals with the original signals predicted by the
model, the energy and timing resolutions of the data are notably enhanced. The
model implementation significantly improved the quality of the particle
identification plot and particle tracks. This method is applicable to similar
problems, such as separating multiple signals or correcting pile-up signals
with other types of noises and backgrounds.

We address the problem of eavesdropping on digital video displays by analyzing the electromagnetic waves that unintentionally emanate from the cables and connectors.
Compared to the analog case (VGA), the digital case is harder due to a 10-bit encoding that results in a much larger bandwidth and non-linear mapping between the observed signal and the pixel's intensity.
The proposed solution is to recast the problem as an inverse problem and train a deep learning module to map the observed electromagnetic signal back to the displayed image.
