physical system is an inverse problem or is based on application to unknown data,
the method in this chapter may be effective.
In Chap. 12, we explain a solution by deep learning, taking an example where an
evolution problem of a physical system is an inverse problem. In other words, it is
a problem to determine the evolution equation itself, when the evolution equation
is unknown and the data before and after the evolution is given. Determining a
system of equations is the most essential part of physics, and using machine learning
techniques on such an aspect can sometimes help to analyze it effectively.
