  For a given entanglement entropy of QFT, we investigate how to reconstruct
its dual geometry by applying the Ryu-Takayanagi formula and the deep learning
method. In the holographic setup, the radial direction of the dual geometry is
identified with the energy scale of the dual QFT. Therefore, the holographic
dual geometry can describe how the QFT changes along the RG flow. Intriguingly,
we show that the reconstructed geometry only from the entanglement entropy data
can give us more information about other physical properties like thermodynamic
quantities in the IR region.
