We argue that the particular choice of coordinatization should not affect a network's inference -- it should be coordinate independent.

From the BTZ black hole to JT gravity: geometrizing the island

A partial dimensional reduction of AdS$_3$ in Poincar\'e coordinates leads to an extremal 2D black hole in JT gravity coupled to a 'bath': the holographic dual of the remainder of the 3D spacetime.
